Hi, my dog has, over the last year or so, developed some major issues with his skin. It started out with his paws and he would constantly be licking them until they got raw and started bleeding. Then spring came this year and he started getting these huge bumps under his fur. Recently his neck got so bad that overnight he was nibbling and scratching so much that the next morning a huge patch of fur was missing and there was dried blood everywhere. I'm afraid it will get infected, but I guess we haven't been able to take him to the vet due to some money issues as well as not having time. He is a Great Dane and he is turning two years old soon. He developed these allergies (if what I'm thinking is correct) at about a year old. My question is: what are your thoughts on what may be going on and please please please any advice??
