A few months ago I had the vet out on a regular basis because my horse was ill. He was excessively drinking and had little urination. His sheath and legs filled to excessive amounts and he was of food.
A biopsy was done and it showed up inflammation in his hind gut. He is controlled by steroids but when we reduce the quantity down he starts to get runny poo again and goes off eating.
This morning his hind legs have filled up again but still on a high dose of steroids. Any idea why this keeps happening and what can we do?
I was thinking about asking my vet for a allergy test and if a investigation op would be worth while.
