My daughters horse apparently got into or ate something in his field today and broke out in huge hives and now he is loosing hair on the hives! The vet was called and gave him a horsey benadryl (sp?) to soothe the itching and a cool hosing along with some bute for discomfort. What on earth would cause this??
He has had hives off and on for the last 2-3 weeks--kind of like a contact dermatitis type thing because they didn't cause any discomfort and usually went away very quickly.
We went into his field and took down wild rose bushes and some other brush but any other ideas?? And why the hair loss??
