Our 9 y.o. English Bulldog, Max, is experiencing a very itchy face only on the right side. He will scratch daily and it sometimes becomes raw. We have moved to Colorado, but have not established a veterinarian here yet. With COVID-19, I do not want to take him out to the vet unless it is the only way to treat this. Is there something I can get online? I have seen great reviews for Coat Defense which, according to reviews, is used successfully for itchy skin on horses, dogs, and cats. Do you have any experience with that product or is there something else that could address both the itchiness and the root of the problem that you might suggest?
