Hurricane Irma Statement From PSEH

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


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.

drwaston ocular

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

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.

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.

Under Tack Dynamic Respiratory Scope

on Thursday, 21 April 2011. Posted in Diagnostic Techniques

Under Tack Dynamic Respiratory Scope

Peterson & Smith now has a new dynamic respiratory endoscope to use for obtaining under tack images of a horse’s pharynx and larynx.   Unlike scoping on a treadmill this endoscope is worn on the saddle pad of the horse while it is training on the track under natural conditions.  The images are transferred to a computer for complete analysis when the exam is over, but some of the video can be viewed on a wireless monitor while the horse is training as long as the horse is not too far away.
