Thank you. We are going to continue his antibiotics as advised by the vet. I'm going to schedule allergy testing with the dermatologist in a couple of weeks. He's not very keen on the vet to begin with but having him poked at more while he's so sore probably isn't a good idea. I thought he was looking better yesterday until we gave him his bath. It's so much worse than I thought. We are doing a lot of research and think we have found some answers. Right now, priority one is just getting him healed up enough to tolerate allergy testing without going crazy and biting someone. I appreciate all of the support. I don't want to put him down...he's my big loves. Here is a photo of before and after his bath last night, which was very gentle. His fur and skin is just falling off in hunks. My husband shaved down as much as Winston would let us and hopefully, sooner rather than later, he will be all healed up so we can get to the bottom of this. Thank you all and I'll update you if anything new pops up!
