2 different horses...2 different problems... one senior has a runny eye..leaks with or without a fly mask and he isn't allergic to anything...seems to be just the one eye...what could be causing this?
2nd senior has a chronic reoccuring runny nose..white kinda discharge..coughs alot. He is allergic to alot of things..including his own dander but there is a vet comming out friday afternoon for another horse and I am considering splitting the field call but I love the opinions of COTHers! He is very old..almost 30..and is ridden 2x a week. riding often times clears up the discharge (gets it running more) and I do often times give him Air Power in the am and again before excercise. (Its smells just like an old man's methol cough drop ) sinus infection? cold? poor old guy his appetite is fine and he rides fine...just so much snot!
The runny eyed horse rocks a fly mask darn near 24/7. Its only the left eye... and its not a whole lot but it def looks like he has been crying when you take it off and it leave a faint crust under the lower palpebral sulcus.
I've had/have horses with both of your horses' problems. The nasal discharge/cough is maybe IAD (inflammatory airway disease), which is sort of a precurser to heaves. The horse that has this is 16, and the IAD was discovered after a CBC showed increased white blood cells, an endoscopy was done, lung x-ray, and bronchial alveolar lavage. He was put on a course of antibiotics for a couple of weeks, then a tapering dose of prednisolone. i have to keep him on shavings, wet his grain, wet his hay, keep him outside as much as possible, etc. as dust seems to aggrevate his condition. He's doing well -
My other horse, the one with the runny eye - well, I never did figure that one out. He, too, looked like he'd been crying I had the vet look at his eyes every time he'd come out. This horse was in his late teens when it started...and it never got worse, but also never got better (this horse has since died). So no help on this one
My older gelding presented with on/off eye crusties. Some days it was gone entirely, other days he'd come in from turnout all goopy. He had a blocked tear duct, the vet flushed it and it's good as new. Very simple and inexpensive treatment. Worth having the vet out for an eye exam to check that.
