Hello, does anyone know what causes pigs to have a wet bum? My girl of 3 years has been to the vet twice, first it was due to losing weight (which she still is) and secondnly for the wet bottom... She had a weeks dose of baytril and a weeks dose of anti inflammatory and nothing has worked. She had a scan for stones which showed nothing... Don't know what else we can do but she has urine scolds
