Preventing injury in race horsesUp to 30% of Thoroughbred racehorses and other elite ath-letes suffer from superficial digital flexor tendon (SDFT) injuries, resulting in long periods when they cannot work. SDFT injuries also force them into early retirement. Pre-vention would be the optimum strategy. Researchers and industry gathered in 2012 at the University of Glasgow. Their focus:• Useful, practical prevention information for trainers,• Technologies that could assist in detecting the problem

earlier with a goal toward prevention, and• What the laboratory could do to aid prevention, diagno-

sis and treatment.Here’s what they discussed:one of the biggest obstacles to accomplishing the re-

search is the racing industry itself. It just is not practical to do the necessary field research in this high-pressure environment. Trainers come at this problem differently and are unlikely to standardize training regimens to “test” their effects. However, modern technologies, such as global positioning system (GpS) and portable moni-toring devices could provide accurate measurements.

Another difficulty is what potential risks should be targeted. A large contributor to the problem is the type of racing the horse does, e.g. National Hunt vs. flat rac-ing. other contributors are age, “types” of horses, and the natural pathology of the injury.

Then there are the potential risks that are hotly debat-ed. These include surface conditions at the track, faster racing speeds, the horse’s fitness and its conformation.

Quite a few complex horse and management factors interact with external conditions, for instance the SDFT core becomes warmer during galloping. core hyperther-mia of the SDFT in relationship to environmental tem-peratures and limb insulation has not been measured. Would something as simple as an ice boot help the horse?

Training and racing history could be a factor, but it is difficult to relate tendon injury risk to previous training and racing.

There could be accumulative microdamage to the tendon during racing. Training might not be intense enough to induce the adaption and remodeling needed to prevent serious injury. However, the literature does not address how intense the training should be.

This is based on an open source article with much more information, and is available here: http://onlinelibrary.wiley.com/doi/10.1111/evj.12269/abstract

A key problem in all research approaches is detecting subclinical pathology as early as possible, and time was devoted to good imaging.

Significant work is needed to link factors responsible for lesion development with measures to prevent their further progression or to reverse the pathology. These might include changing training regimens, optimal sur-face choices and how often a horse races. MeV

Geriatric horses do not necessarily do worse than ma-ture, non-geriatric horses after colic surgery, according to results presented at the annual meeting of the American Association of Equine practitioners in Nashville.

“I do not think we should be reluctant to pursue surgery for colic in the geriatric horse,” said Deanna M. gazzerro, VMD, a surgical resident at Tufts Univer-sity cummings School of Veteri-nary Medicine.

Gazzerro presented data from a retrospective study she did while at the New bolton center, Univer-sity of pennsylvania. Gazzerro and her colleagues reviewed the medi-cal records of 78 geriatric horses that were 20 years or older and compared those with the medi-cal records of 156 mature horses, which were between 4 and 15 years old looking at post operative complications after colic surgery.

“We eliminated the 16- to 19-year-olds from the study to re-

ally differentiate between geriatric and non geriatric group,” Gazzerro explained.

They reviewed the records for history, signalment, examination findings and blood work on ad-mission, intraoperative findings, surgery time, findings during surgery, type of lesion, whether the small or large intestine was in-volved and any postoperative care, such as treatments and complica-tions, as well as whether they were alive at discharge and duration of

hospitalization.“As far as postoperative com-

plications go, we pretty much looked at everything you could look at, including postoperative reflux, diarrhea, fever, problems with the incision, colic, need for second surgery, pneumonia, appe-tite and laminitis,” she said.

The most common lesion type in the geriatric horse (60% ) was the small intestinal strangulating lesion. In mature horses, about 40% had a large intestinal simple

obstruction or displacement. “The difference in the le-

sion distribution among the two groups was significant, and we found that the geriatrics had a sig-nificantly increased odds ratio of having an intestinal strangulating lesion—about six times more than mature non-geriatric horses,” she explained.

This was an important statistic, because when they looked at com-plications, the type of lesion, rath-er than the age of the horse was

the most significant risk factor.postoperative reflux is an im-

portant complication follow-ing surgery for a small intestinal strangulating lesion. Thirty-five percent of geriatric horses vs. 17% of mature horses had postop-erative reflux, so on the surface, it looked like geriatric horses fared worse from surgery. However, when they did a statistical analysis of the data, they found that a simi-lar percentage of mature horses who had a small intestinal stran-

gulating lesion had postoperative reflux, according to Gazzerro. Forty-seven percent of mature and 47% of geriatric horses with small intestinal strangulating lesions had postoperative reflux.

“When we did a multivariable analysis, age was not associated with reflux, instead, we found the reflux was due more to the type of lesion than the horse’s age,” she explained. other postopera-

tive considerations attributable to the small intestinal strangulations were the need for IV lidocaine and promotility agents after surgery, a higher peak heart rate and persis-tent tachycardia.

Twenty-three percent of the geriatric horses had inappetence after surgery, which was a con-cern. “overall inappetence was

about four times greater in geriat-ric horses compared with mature horses, particularly for geriatric horses that had small intestinal le-sions.”

The researchers were unsure of the pathophysiology of the in-appetence, which could be due to some metabolic derangement, pain or ileus shock or “any num-ber of things.” However, nutri-tional support for geriatric horses

after colic surgery should be an im-

portant consider-ation when moving forward.

She recommended more sup-portive care in the postoperative period, making sure they get good pain management and keeping an eye on metabolism, specifically monitoring triglyceride levels and providing intravenous nutritional supplementation if necessary. She also suggested taking them out

and hand grazing them. In the long-term, most of the

geriatric horses did well with 68 (87%) of the geriatrics surviving to discharge vs. 144 (92%) of the mature horses.

She said in all the horses, com-plications such as post operative reflux, fever, diarrhea, colic, a sec-ond surgery and laminitis were all associated with decreased sur-vival.

because a high proportion of geriatric horses have small intes-tinal strangulating lesions, this should prompt veterinarians to have this high on their differen-tial list and to refer to a surgical facility sooner rather than later. regardless of age, small intestinal strangulation was associated with postoperative reflux, and owners should be advised of this poten-tial complication pre-operatively. When talking with owners about the horse’s options, keep in mind, “these guys don’t necessarily do worse,” Gazzerro said.

Although it was not part of the study, after her presentation, one veterinarian asked about recov-ery from anesthesia, which can

be a concern. Gazzerro said that recovery is not necessarily harder on a geriatric horse. “Unless they have a significant lameness or se-vere orthopedic problems, I don’t generally feel like we see any worse recovery compared with mature horses,” she said. “They might sleep a little longer because they like the soft mats we use in the re-covery stall.” MeV

It is often assumed that giv-ing birth is both stressful and pain-ful for the mother. This may be the case for humans but does it also apply to horses or are we trans-ferring human experiences to the animals?

Scientists at the University of Veterinary Medicine, Vienna (Vetmeduni) have investigated the stress associated with birth in horses and other domestic animals. The findings show that contrary to expectations horse mares appear to be completely relaxed when foal-ing. The results are published in the journal Theriogenology.

Equine foaling is typically quick. Labor and the active part of foaling, resulting in delivery of the foal, take 10 to 20 minutes and is considerably shorter than giving birth in humans or in cows. Is this brief period stressful for the ani-mals or are horses more relaxed than humans when giving birth? This issue has been addressed by Christina Nagel, MSc, phD, and colleagues, who closely observed 17 foalings at the brandenburg State Stud in Neustadt (Dosse), Germany, as well as recording

electrocardiograms before, during and after foaling.

The researchers also took sam-ples of saliva and blood to analyze the levels of stress hormones, such as cortisol and epinephrine. “Nor-mal foaling appears to cause just the opposite of a stress response,” Nagel said.

Surprisingly, during labor the heart rate of mares does not in-crease. on the contrary, the mares even miss some individual heart beats due to delayed stimulus con-duction in the heart. In humans, such second-degree atriventricu-lar (AV) blocks often require med-ical treatment but many healthy horses show AV blocks at rest. on physical activity, e.g. when the horse is ridden, the heart beat becomes regular and the beat fre-quency increases.

The finding of AV blocks dur-ing foaling suggests that mares are strongly influenced by the parasympathetic nervous system, which usually causes a state of rest and relaxation. Its antagonist, the sympathetic nervous system, would prepare the organism for a stress response but does not seem

to be active while the animals are giving birth.

The level of stress hormones remains low in foaling mares and the researchers did not find an adrenaline rush at any point. Foal-ing clearly does not evoke a stress response. The need to care for the newly born foal was also not perceived as stressful: contact be-tween the mare and the foal was associated with a further state of relief and relaxation.

very differently from human mothers. They need a safe envi-ronment to give birth: all the foals in the study were born at night, when the stable was quiet.

“parturition in horses requires a state of relaxation in the mare. This is an advantage in wild horses

because mares can postpone la-bour until they perceive the envi-ronment as calm and safe. once this is the case, foaling proceeds within a very short time,” ex-plained Christine Aurich, DVM, phD, Diplomate of the European college for Animal reproduction

(EcAr), who is the head of the re-search group.

The study was conducted at the Graf Lehndorff Institute for Equine Science, a joint research unit of the Vetmeduni Vienna and the bran-denburg State Stud Farm at Neus-tadt (Dosse), Germany. MeV

The need to care for the newly born foal was also not perceived as stressful. Contact between the mare and the foal was associated with a further state of relief and relaxation.


Genotyping allows scientists to choose the embryos they want to use based on different criteria: sex, like in this experiment, the absence of known genetic disorders, or, perhaps in the future, other traits that are tied to behavior, such as emotivity or sociability.

Four Foalsfrom genotyped, cryopreserved embryos born in europe


What were the steps leading up to the birth of these foals?

Seven days after fertilization, embryos were collected from Welsh b ponies that are part of INrA’s livestock. The embryos were genotyped: scientists sam-pled some of the embryos’ cells to analyze their genomes. In this experiment, embryos were selected based on sex, the idea being to use sex-based selec-tion to test the technique’s fea-sibility. The embryos were then cryopreserved in liquid nitrogen (at -196°). Last summer, they were transferred into saddlebred mares at the Haras du pin center. After an 11-month gestation pe-riod, the foals were born in May. They were of the expected sex: two females and two males.

This is the first time that such an event has taken place in Eu-rope, and it is the product of more than 10 years of various types of embryonic research car-ried out by INrA and IFcE sci-entists.

What made it so difficult to apply this technique to horses?

Although embryo preserva-tion techniques are already well developed for bovines, small ruminant species, and even humans, preserving horse em-bryos is a complex process. For instance, horse embryos vary greatly in size: 7-day-old em-

bryos range in diameter from 200 to 700 µm. It is difficult to cryopreserve the largest em-bryos because the liquid inside them forms ice crystals when the embryos are frozen at very cold temperatures. What’s more, horse embryos are surrounded by a capsule that interferes with successful cryopreservation.

What is the significance of this event, which is the first of its kind in Europe?

There are several reasons why being able to successfully cryopreserve embryos is impor-tant. For example, it allows us to maintain breed genetic diversity,

particularly that of breeds with small population sizes, such as the Landais or the poitevin Mu-lassier. Furthermore, the factor that currently limits the use of embryo transfer is its cost: the transfer center has to maintain a team of recipient mares that are reproductively synchro-nized with the donor mares. cryopreservation means that the transfer doesn’t have to take place immediately; it can wait until a recipient mare becomes available to receive the embryo. Finally, it may now be possible to directly repopulate horse herds that have experienced losses as a result of various issues, such as disease-related problems, in-stead of having to use the indi-rect technique of crossbreeding.

Why genotype the embryos?Genotyping allows us to

choose the embryos we want to use based on different criteria: sex, like in this experiment, the absence of known genetic disor-ders, or, perhaps in the future, other traits that are tied to be-havior, such as emotivity or so-ciability. It is advantageous for the horse industry to be able to determine the traits of a future foal. We will next aim to simplify the process—to make this tech-nology more accessible and user friendly for those in the horse in-dustry. MeV

Researchers from the Institut Francais du Che-val et de l’equitation (IFCE) and the French Nation-al Institute for Agricultural Research (INRA) an-nounced that, for the first time in Europe, four foals were successfully born as the result of the transfer of genotyped and cryopreserved embryos. The goal of this work is to better understand embryonic develop-ment, control livestock reproduction and maintain breed genetic diversity. Furthermore, it is advanta-geous for the horse industry to be able to determine the traits of a future foal.

The INRA Val de Loire center at Nouzilly is where the technology to maintain embryo viability follow-ing genotyping and cryopreservation was honed, and then, last summer, the transfer of several embryos took place at the IFCE Haras du Pin Stud Farm, lo-cated in the French department of Orne. The part-nership between the two institutions has now been cemented by the birth of the healthy foals.

The press departments of the institutions released this question and answer interview about the process.

“EQStable app users spoke and the Zo-etis Equine Team listened,” said Kate rus-so, marketing manager, U.S. cattle and Equine Marketing, Zoetis. “The EQStable app updates are a direct result of the feed-back received through the app, to offer the organization and health care information users want to provide the best possible care for their horse or herd.”

The updated EQStable app is available for free at the Apple App Store. Among the new features is a deworming ques-tionnaire to help determine their horse’s parasite risk profile and create an Indi-vidualized Deworming (ID) plan.

“The new AAEp parasite control Guidelines support that de-worming paradigms have changed from the same rotation for ev-ery horse to a strategic approach with consideration to each horse’s individual risk factors. The Individualized Deworming Question-naire was developed to assist horse owners in developing a current deworming approach,” russo said. “Each situation is different so it important to work with your veterinarian to determine the appro-priate seasonality and duration of all deworming products.

The calendar reminders don’t stop with deworming. The app

allows users to set specific dates and customize reminders health-care, events and trips.

The new version also offers a tutorial video for using the app. It’s broken down by chapters so you can find sections of the video that are most useful to you.

Users can enjoy all of the updates the app has to offer:• Deworming questionnaire: changes are within the My Stable/

Events/Deworming sections. This new questionnaire helps determine an ID plan for a horse or herd.

• Tutorial video: Simply tap the breakdown times to jump to sections of the video.

• Set specific dates for events: changes within the My Stable/Events/Shoeing and Dentistry sections. Enter specific dates and customize reminders.

• other events: changes to the My Stable/Events/other sec-tions. Add other events from different sections; previously, it was pulled from the calendar only.

“The Zoetis Equine Team hopes that version 3.0 of the EQStable app delivers all of the improvements that users were asking for,” russo said. Now owners can work with the veterinarian to develop and maintain an individualized deworming program, as well as never miss an important appointment, russo added.

Equine herpesvirus (EHV) has been reported in multiple states throughout the country.

belmont park in Nassau county, New york, in-stituted a precautionary quarantine in late June after a horse showed signs of EHV-1. An unraced 2-year-old colt was experiencing fever and neurological symptoms. There were 51 horses in that barn under quarantine.

Another quarantine was in place at Suffolk Downs in boston following the death of one horse stabled there. The horse, which was transferred to Tufts University School of Veterinary Medicine, with neurological signs, was diagnosed with equine herpes myeloencephalopathy (EHM). An-other horse came down with fever.

The Kansas Department of Agricul-ture reported that a horse in northeast Kansas had been confirmed positive with a wild type of non-neurotropic case of EHV-1. The horse had been at a large barrel-racing event in Lincoln, Neb. Another horse from Wisconsin, which was at the same barrel-racing event, had been confirmed positive with EHV-1.

At least nine horses displayed EHV signs in Min-

eHv-1 reported in several states

nesota and four of those tested positive for EHV-1. Two of the horses had to be euthanized. The others appeared to be recovering.

There were also reports from colorado, North carolina and Virginia.

Beth Davis, DVM, phD, DAcVIM, professor and section head of equine medicine and surgery at Kansas State University's Veterinary Health cen-ter, said horse owners should check their horses for symptoms, especially if they have recently been to an equine event. Veterinarians in these states should warn their clients to be vigilant.

“If a horse has been at an event where there are a large number of horses and there was a case of equine herpes myelitis, keep an eye on that horse to make sure it is doing what it normally does,” Davis said. Take its temperature twice a day to make sure it is normal because the first sign of the virus is a fever greater than 101.5° F. “The horse may then resolve that fever, but in another day or two the horse will have another fever spike,” Davis said. “Those may be the only clinical signs that the horse shows.”

Equine EHV-1 can cause respiratory and neuro-logical symptoms, abortion in mares, and neonatal foal death. EHM, the neurological form of the virus, has a high morbidity and mortality rate.

EHV-1 spreads easily through direct horse-to-horse contact, but can also be spread by fomites on physical objects, such as tack and grooming equip-ment, as well as feed and water buckets. biosecurity is essential to protect unaffected horses.

Incubation is between 2 and 10 days. respiratory shedding of the virus generally occurs for 7-10 days but may persist longer in infected horses. For this reason, the isolation period recommendation for con-firmed positive EHM cases is 21 days. clinical signs of EHM in horses may include nasal discharge, incoordi-nation, hindquarter weakness, recumbency, lethargy, urinary incontinence, and diminished tail tone. The prognosis for EHM positive horses depends on the severity of signs and the period of recumbency. Em-ploying supportive treatment with intravenous fluids, anti-inflammatory drugs, antiviral drugs, and other

lessons learned from eHM in va Virginia was fortunate with the recent case of EHM in April, according to

richard Wilkes, DVM, State Veterinarian with the Virginia Department of Agriculture and Consumer Services (VDACS).

A horse in Fauquier was diagnosed with EHM and euthanized on April 10, but no other horses showed signed of illness at that farm or from a steeplechase event in which the horse participated prior to becoming ill. This was due both to good luck as well as a good response.

“We owe a debt of gratitude to the farm’s stable manager,” said Wilkes. “He recognized immediately that something was wrong with the horse because it was not eating and had a fever. He called the veterinarian as soon as the horse began to have neurological signs, and the veterinarian quickly submitted samples to the VDACS laboratory to be tested for EHM. Due to the positive test result and the severity of the clinical signs, the owner chose to euthanize the affected horse the same day the diagnosis was reported by the lab, which minimized the chances of further spread of the virus. This particular farm already practiced excellent biosecurity but stepped that up.”

Wilkes suggested veterinarians provide this advice for owners, trainers and others around the stable.

• Practice biosecurity routinely. Do not share tack among horses and minimize direct contact among assembled horses whenever possible. People can spread the disease, too, if their hands, clothing, shoes or vehicles are contaminated, so wear coveralls, boot covers or use disinfectant baths if feasible. Isolate and closely monitor horses that are returning from a show, trail ride or competition for a minimum of 14 days.

• Be aware. Horse exhibitors and event goers should monitor their horses for early signs of infection by taking their temperature twice a day while at shows and report an elevated temperature to their veterinarian. Look for neurologic signs indicative of EHM - wobbly gait, hind-end weakness and dribbling of urine - and call your vet early if you are concerned. Don’t wait. You know your horse and if you are concerned, call the vet now.

In many states, EHM is a reportable disease, so veterinarians should report suspected cases to the state veterinarian.

supportive measures may be beneficial, since there is no specific treatment for EHM, according to proMed-Mail, an e-mail infectious disease alert service.

currently, no EHV-1 equine vaccine has a label claim for protection against the neurological strain of the virus. MeV

The days of closing the stall door and walking away are gone. Horses are thinking animals, and thinking animals must be

engaged. Engagement keeps them happier and makes them better patients.

Help a horse stay engaged during times of restricted activity with an active box rest regime. It takes effort to put all of these ideas to action but the end results will be a happier, healthier horse that can return back to work faster and stronger.

Always keep the original injury in mind as well as the restrictions that might be necessary for healing which requires working closely with the veterinarians when designing engagement activities, but many of the tips here can be modified to accommodate the horse’s needs.

Happy Feet. Start with deep bedding to help

reduce bed sores for those that spend increased time down off their feet. The increased bedding will also pro-vide some dryness which can help avoid thrush when also combined with twice a day cleaning.

room witH a view? overlooking nearby

paddocks with a window, a view of the arena or even

the farrier stall? It’s reality TV for horses and may help keep them entertained for hours.

Food For tHougHt. reduce calorie/energy

rich pelleted feeds with a basic ration balancer will keep hot heads a bit more level and help prevent unnecessary weight gain.

. rock out Feed time. Use several large rocks

in the grain bin to slow down the consumption of grain or pellet feeds. This will make reduced rations go a bit further while working them around the bucket to get every last piece.

making tHe best oF meals. Nibble hay

bags have smaller holes than traditional hay nets or bags. This makes a tougher task of chow down hay ra-tions in the blink of an eye. For the truly talented speedy eaters, try a double nibble bag.

Quality time. Take time to work on basic

ground manners or even learn a few tricks. Spending extra quality time will both strengthen the bond be-tween horse and rider and keep idle minds active.

continue a diligent grooming rou-

tine. Sitting idol in a stall can result in increased dust particles building up in the hair coat. Daily brushing will help reduce the dusts and circulate the healthy oils in the coat.

consider companions. Since horses are herd animals, the stress of being separated could cre-ate new problems like gastric ulcers or developing stall vices. consider having other horses take turns being a buddy for the day. If a buddy horse is not an option, consider other species

toys For tots. A quick trip down the little

tots toy section of your local toy store will reveal a va-riety of stimulating musical toys that have large buttons that are easily pushed by a muzzle and made of heavy plastics that can withstand the torment of a horse when mounted up in a stall.

mind benders. Jolly ball®, Amazing Graze®,

and Uncle Jimmy’s Hangin ball® are just a few of the toys designed specifically with equid entertainment in mind. or just hand an empty 2 L pop bottle or milk jug on a twine with a few rocks for some homemade maracas that are fun to crush and shake!

stretcH & strengtHening exercis-

es. Stretching is a great way to help maintain flexibil-ity, strength and mobilization of joints not affected

by injury. There are a variety of lateral stretches that can help maintain and even strengthen the muscles in the head, neck and core of the horse without caus-ing excessive movement of limbs. Manual manipula-tion of limbs including subtle flexions, protraction, abduction and more can help maintain strength and muscle tone.

spa day. Staying on top of the strain that sup-portive limbs can endure will go a long way in the crea-ture comfort. While deep penetrating muscle massage should be reserved for the professional, even a horse owner can help provide relief with some superficial in-formal massage. Massage helps promote circulation to surrounding tissues and provide tension relief. MeV

Expanding its capacity to offer emergency and specialty care for horses, Cornell Ruffian Equine Specialists (CRES) has hired three new equine veterinarians. As surgeons and emergency clinicians they will help build the new referral and emergency care practice, which opened in spring 2014 near the Belmont Racetrack backstretch in Elmont, NY as an extension of the Cornell University Hospital for Animals.

caring for horses eases symptoms of dementiaIn the first study of its kind, researchers have de-

termined that spending time with horses eases symp-toms of dementia due to Alzheimer disease.

A collaboration between The ohio State University, an equine therapy center and an adult daycare center found that people with Alzheimer were able to safely groom, feed and walk horses under supervision, and the experience buoyed their mood and made them less likely to resist care or become upset later in the day.

The small pilot study, which appears in the journal Anthrozoös, suggested that equine therapy, a treat-ment used today for children and teens who have emotional and developmental dis-orders, could work for adults, too.

Holly Dabelko-schoeny, as-sociate professor of social work at ohio State, said that equine ther-apy could supplement more com-mon forms of animal therapy in-volving dogs or cats and provide a unique way to ease the symptoms of dementia without drugs.

"We wanted to test whether people with dementia could have positive interactions with horses, and we found that they can — ab-solutely," Dabelko-Schoeny said. "The experience immediately lift-ed their mood, and we saw a con-nection to fewer incidents of nega-tive behavior."

In addition to memory loss, people with Alzheimer's often experience personality changes, she explained. They can become depressed, withdrawn — even ag-gressive. As researchers look for a way to prevent or treat the disease, today's therapies are becoming more focused on how to ease the emo-tional burden for patients and their families.

At the adult daycare center, a National church residences center for Senior Health in downtown columbus, clients normally partake in crafts, exercise and other activities to manage their dementia. For this study, 16 of the center's clients volunteered to break with their regular routine.

once a week, eight of the clients would remain at the center and pursue other activities while the other eight took a bus trip to the Field of Dreams Equine Education center in blacklick, ohio. There, they vis-ited with horses under the supervision of National church residences caretakers, as well as faculty and students from the college of Social Work and the col-lege of Veterinary Medicine at ohio State.

The clients visited the farm once a week for a month, so that every participant had four total visits. They groomed and bathed the horses, walked them, and fed them buckets of grass.

The four horses were chosen for their gentle dis-positions and calmness when facing new people and new situations.

The researchers saw obvious signs that the clients enjoyed their time on the farm: they smiled, laughed and talked to the horses. Even those who normally act-ed withdrawn became fully engaged in the experience. There was a clear improvement in dementia-related be-havior among the clients who visited the farm. MeV

In addition to memory loss, people with Alzheimer's often experience personality changes. They can become depressed, withdrawn — even aggressive. in the first study of its kind, researchers have determined that spending time with horses eases symptoms of Alzheimer's dementia.
