Hurricane Irma Statement From PSEH

Posted in Equine general medicine, General, Diagnostic Techniques, News, Equine ophthalmology, Blog


Dear Peterson & Smith Family and Friends,
As we prepare for Hurricane Irma, please keep safety in mind at all times. As always, our referral hospital will be staffed to function on an emergency basis. Please make every attempt to contact us at >>> 352-237-6151 before loading up and bringing your horse to the hospital. Also, do not try to trailer your horse under unsafe conditions.

Ambulatory services will be available as the situation permits. Safety is paramount, and we will not risk the safety of our staff and potentially add to the challenges faced by first responders in our community by sending our staff into harm’s way.

We urge you to prepare yourselves and your horses for the worst-case scenario. If evacuation is an option, please consider it. The Florida Department of Agriculture has temporarily suspended the interstate movement requirements for horses evacuating due to Irma.

When stocking up on supplies, remember to also stock up on any medications or medical supplies needed for your horses. Our office will be open until 12 pm Saturday, and we hope to reopen Tuesday morning.

As Floridians, we are accustomed to preparing for hurricanes on an almost yearly basis. We always hope that our preparation efforts are for naught. However, it is always prudent to wish for the best and prepare for the worst. If you have any medical concerns about preparing your horse to weather the storm, please contact your veterinarian.
We are here for you, and together we will stand through this time.

10 year old, Haflinger, Mare 

Presented for squinting, excessive tearing and recent cloudiness of her right eye. 

Ophthalmic examination: Revealed eyelashes on the upper lid angled down, blepharospasm (closing of the eyelids), and corneal edema (cloudiness of the eye). Reflex tests revealed a positive menace. These include: vision test – a light perception test; palpebral - a sensory test, and pupillary light reflexes (PLR) - evaluating the retina, nerves and muscles. Positive results to these tests yield an improved prognosis.

Esophageal Obstruction (“Choke”) VetNotes

Posted in Equine general medicine, General, Diagnostic Techniques, Blog

Myhre VetNotes

Esophageal obstruction is when food (or bedding and other foreign material) are swallowed and get stuck in between the back of the mouth and the stomach. There are two tubes that lead out of the mouth, one for food (the esophagus) and one for air (the trachea). Most commonly this occurs at the beginning of the esophagus just behind the mouth, or just before the end of the neck. This can often be figured out just by watching your horse. Horses typically cough repeatedly and often retch, have food or saliva coming out of their nose, and frequently try to swallow. A veterinarian will attempt to pass a nasogastric tube into your horse’s nose and into their stomach. In many cases, the choke will have resolved before the veterinarian gets there, but in slightly more severe cases this will push the obstruction into the stomach and resolve the choke. In very severe cases the tube will not be able to pass beyond the obstruction. Further confirmation can be achieved using a camera to actually see the obstruction, but this depends on the situation. 

Taking A Closer Look at: Condylar Fractures in Horses

Audio Transcription from The Horse Talk Show on March 18th, 2017
 Featuring: Tim M. Lynch, DVM, Diplomate, ACVS, ACVSMR

Lou Barton: There’s a topic that’s on everyone’s mind:  Mastery, of course, one of the favorites on the derby trail, a possible contender. Certainly, Jimmy Barnes, assistant to Bob Baffert, said he was a horse to watch. We met him at the Breeder's Cup Classic last year. Lovely horse. Sadly, he had to have surgery this past Monday for a Condylar Fracture. When Jimmy texted me he said he was absolutely gutted...he didn't see it coming. I don’t think you can really see those things coming, and I know Jimmy, being the horseman that he is, if there were any signs he certainly would have noticed. So, Dr. Lynch, tell us what a condylar fracture is.

Sport Horse Injuries Talk with Dr. Meeks

Audio Transcription from January 21st, 2017 on the Horse Talk Show
Check out more audio on
Lou Barton: We see a lot of horses competing at the highest levels such as the Nation’s Cup and the $1 Million Grand Prix, and I’m sure there are a lot of ongoing issues and concerns with injuries in these horses. So, could you start off by talking to us about the most common sports injury that you see?
Dr. Meeks: There are a wide variety of injuries that I see and it depends on the horse. In the HITs horse’s the jumpers, you see a lot of suspensory injuries that are common. Usually, the front end of the horse is affected, but we do see some hind injuries. We see horses going at high speeds, going over jumps, you tend to come down with a lot of force and put weight on their front that’s probably one of the most common injuries that I see. But we also see a lot of bone bruising, also you have the various flexor tendon injuries, muscle soreness that goes along day in and day out training. These horses are in training and have a training regiment and they do what they're supposed to do, but it does put a lot of stress on the horse. So there’s a lot going on at the same time. 

3 Breeding Options That Are Proven To Foal Your Mare

Posted in Equine general medicine, General, Diagnostic Techniques, Blog


Vet Segment from The Horse Talk Show

Audio Transcription from January 7, 2017- Dr. Phil Matthews

Lengthening the Day

I always try to simplify things for my clients and in my mind, so I put all mares in 3 categories:

1)    Maiden Mare (never had a foal)

2)    Barren Mare (not pregnant but has had a foal)

3)    Foaling Mare (who is in foal)

For our discussion today, we will leave out in Foal Mare; the other two categories are the Maiden and Barren Mare. But I think what people need to think about if they are novices in the breeding world, is that the mare is a seasonal breeder. About 80-90% stop cycling during the winter months, and that’s a function of the daylight (photoperiod) when the days become short. This triggers a hormone in the brain and the brain shuts their ovaries down. If we want to breed our mares in February and early March, we have to trick them and have to get them to think that daylight is getting longer by using artificial lights. That’s an important component in trying to get early foals.

Roarers—Recurrent laryngeal neuropathy VetNotes

Posted in Equine general medicine, Blog


              Recurrent laryngeal neuropathy, often referred to by the colloquial term of “roaring,” is an inability of a horse to fully abduct (open) the arytenoid cartilages in the larynx, thereby resulting in a hollow whistle on inspiration during exercise. The development behind the roaring disease process is not fully under-stood, but is due to damage to the recur-rent laryngeal nerve which innervates the muscle responsible for opening the arytenoids. This nerve travels from the brain, down the neck to the chest and then turns, traveling back up the neck to the larynx. The left nerve is longer than the right and makes its turn around the aorta. Typical cases thought to have a hereditary component involve the left side only.

Enteroliths in Horses

on Tuesday, 05 March 2013. Posted in Equine general medicine

Enteroliths in Horses

Often referred to as "pearls" or "gut rocks," enteroliths are a phenomeon in horses, that can cause colic. When horses ingest a particle that it can't fully digest, the horse's body forms an enterolith in an attempt to protect itself. Particles that cause enteroliths can be anything from string to pebbles. However, recently, Dr. Hughes encountered a case where a horse had a horse shoe nail embedded in an enterolith. She took the time to explain the case and enteroliths in general, in this month's vet notes. 


Equine Vaccinations - Top Priority

on Wednesday, 08 June 2011. Posted in Equine general medicine

We are being inundated with questions about the Equine Herpes Virus and Eastern Equine Encephalitis.  To help alleviate the concern we have re-issued our Vaccination Recommendations.  They can be found on our website by following this link: PSEH Vaccination Recommendations.

Eastern Equine Encephalitis – have you vaccinated?

on Wednesday, 01 June 2011. Posted in Equine general medicine

Summer is here and horses and people will have an increased risk of exposure to Eastern Equine Encephalitis Virus (EEE)

EEE is a mosquito borne virus that is endemic in the eastern United States. The virus is carried by birds primarily and spread to horses and humans through mosquito bites. The incidence of mosquitoes and therefore infection rate is increased most years during the late summer months and into the fall in central Florida.
