We have a 4 year old yellow Lab- On Sunday she started to develop red sores on her butt area, and by Tuesday the red sores had spread drastically – covering her belly , her legs, and certain points on her face. I also noticed that her ears and face have become very swollen since Sunday. She seems to be very, very thirsty and depressed.
Since we took her to the vet on Wednesday and got her a steroid injection things have gotten more swollen on her face and now she has open sores on her face. The vet also gave her a prescription for presidone(sp).
Any suggestions? We have considered the possibility of an allergic reaction but thought that her reaction may have been more immediate instead of progressively getting worse.
