This four year old gelding was presented with swelling and difficulty peeing.  Initially we thought he had been kicked but at sedation a Loonie sized kidney/bladder stone was removed from his urethra, at the end of his penis.  This gelding may have to have his penis amputated, we are treating him conservatively and are still hopeful.

October 4, 2011 update

This four year old gelding recovered very well.  Recently he began exhibiting similar symptoms as before, the result was another huge stone removed from his penis.  His diet and water source have been changed.

  Dr. Domoslai here, I would like to update you on an interesting case.  The bucking horse finally succumbed and on post-mortem had his entire kidneys and bladder were filled with large stones (approximately one gallon of material similar to the scale in a tea kettle)

"Heat and Horses"

posted by Horse Owner Today    |   July 20, 2011 08:33

Q:  What is heat stress?

A:  Heat stress is a condition when the horse reaches a temperature above what it can normally thermo regulate i.e. by sweating breathing and otherwise cooling down.

Q:  What causes/contributes to heat stress?

A:  Heat and work and hydration status all contribute to heat stress.

Q:  Is heat stress serious? 

A:  Heat stress can be serious if the condition is not recognized and corrected.

Q:  How can I prevent heat stress? 

A:  First ensure that your horse is adequately hydrated before during and after working him.  Make sure he is on a good balanced ration with adequate salts and minerals in his diet to compensate for that loss by sweating.  Free choice salt is essential for the horse to manage his salt levels.  If conditions are severe or you want to be absolutely sure your horse is hydrated fully an electrolyte solution can be given to him prior to and after working.  Just like the Gatorade adds state proper hydration with water and electrolytes before throughout and after workout.

Q:  How is heat stress treated?

 A:  If your horse is heat stressed it is imperative to stop working him.  Cool him down as soon as possible with wet blankets or hosing him down.  Supply small frequent drinks of water but do not let him gorge on water.  I like a gallon every half hour for two hours then if he is stable allow free access to water.  Walk him slowly to prevent cramping of the muscles and get him into a cool breezy location.  If the horse is going into heat stress shock or is looking like he is not responding,  get veterinary attention as quickly as possible.

In severe heat stress an intravenous electrolyte solution may be used but usually electrolytes added to the water are sufficient.

Bowed Tendon

posted by Horse Owner Today    |   July 19, 2011 07:35

Q:   My OTTB bowed a tendon at 3. He was given two years off and was hand walked and turned out in a small field. I purchased him at 5 with no soundness issues, and the bow had healed so that it was barely noticeable.

He is now 10. We are jumping 2'9 - 3'0 and still having no lameness issues.

I use either polo wraps or woof wear brushing boots when jumping. In terms of prevention, should I be leaving his legs bare? Are boots or polos better?

Could I use boots like Eskadrons on him or should I stick to the softer ones with no shell? Thanks!



A:  With a history of bowed tendon I'd likely keep him good and wrapped whenever you are working him,  the added support might be what he needs.  The Eskadorns are great and you can get some good form fitting boots that will last a long time and hold up to all conditions.  Although it's been seven years without an flare up it certainly is safe to keep him wrapped and you have obviously being doing well with what your using so sometimes why fix something if it doesn't need fixing.




West Nile in Western Canada

posted by Horse Owner Today    |   July 4, 2011 11:25


Q:  What about West Nile this year?

A:  West Nile risk is likely a little higher than last year as we build towards the next increase ie: every 5-6 years.  If we dry up the risk will decrease but we can only monitor trends and watch what happens in south eastern Saskatchewan and Manitoba.  West Nile will hit there first if it is going to be a bad year.  So I’d say overall West Nile risk is yellow.


Equine Rabies Questions

A:  In Sask. we get rabies mostly from bats and skunks,  and it must be saliva from an infected animal to the blood of the horse ie.) the skin must be broken.

A:  Yes a vaccine approved for horses is available and is a one shot modified live vaccine.

Q:  Is there a risk involved with vaccination?  (A stallion died last year after he was vaccinated for rabies.)

A:  All vaccines can cause an anaphalxis and one should always have epinephrine on hand for this.  The vaccine is an modified live vaccine and is approved on label for horses so Id say no greater risk than any other vaccine.

A:  Horses usually get the dumb form of rabies ie depression drooling unable to swallow ie water

Q:  How common is equine rabies? In Sask.? in the southern U.S.?
