Ok so one of the horses in my care has a charming foot abcess which burst out through the heel yesterday. I called my vet and she told me to clean it, apply a poultice (animalintex) and give him a shot of long acting penicillin, all of which I did. He is slightly improved this morning. Changing the poultice every 12 hrs according to instructions on the packet. I've since been told by a few people that antibiotics shouldnt be given for foot abcesses. Not knowing any better I went with what the vet told me. So what are your thoughts?
