I live in Florida. Over the last several weeks, I've been getting a ton of customers with itchy dogs. I'm seeing hot spots and flakey skin on dogs that (I know) the customer takes well care of. Even my dogs are itchy, and I keep them well maintained (grooming, flea/tick prevention, etc.). It's been suggested that it's all the pollen in the air, but I don't know what to do about it. On my dogs, I've tried oatmeal and aloe, dandruff, and medicated shampoos, conditoners and sprays, but none of them work for more than a couple of days. Any suggestions?
