Barb I am not a quack, I have been through the mill with my rescue and he is my boy. I go to an internest, allergist and vet! I say that because max has some sludge in his bladder which will have to come out if worsens, pancreatitus and allergies. He came to me with an awful odor that I diagnosed after a lot of reading and talking on line. Anyway he has had a cyst in his ear, and staph on his belly by his penis, the recommendations where meds that didn't work, because of his pancreas I give him supplement but keep cortisone it a minimum. Buy yourself on line sovereign silver gel. I mix it with sacred franckensense and apply several times a day. It's a very soothing gel. My vet said even the silver alone would have been enough. I don't know if you can buy this in a store in Canada but you certainly can online! It's not expensive ( franckensense is and should be bought through a reputable essential oils dealer if you want to. Max also went from hyper thyroid to now hypothyroid!! Believe me I have been around the block and have learned a lot the past three years. The silver may not help Bacca but it homeopathic and can't hurt! I don't know what's going on inside him but I a have cured two skin issues on the outside. Sounds like those baths are irritating his skin more. My prayers are with you and I k ow how frustrating it is. We do because we love but spending the big money and not knowing is human if it will cure is nothing to feel guilty about!!!!
