I have a 5 year old Golden Retriever who used to be beautiful. Now, his sides are bare, and his tail looks like a rat tail. He's now starting to make sores on his body from chewing. My vet put him on 1.5 mg Triamcinalone twice a day, and he's been on that for over a year. He's also been taking two chlorpheniramine antihistamine pills a day, but things seem to be getting worse if anything. He was on Iams large breed dog food for the first couple years of his life, and when the allergies started, we switched him to lamb and rice to see if it was his food, but that didn't help. We've also tried Benadryl with no results. My vet says that there is not much more we can do, but I've read about the yeast pills, and other medications. The anti-itch shampoo doesn't seem to help much, and after a month or so on fish oil, his allergies were the worst they've been, so we took him off the fish oil. Any suggestions?
