Just see what I learned today. Never heard of using solarcane. If you try the benadryl, try to get a capsule, not caplets. Apparently the capsules disolve quicker and they get the full dose. We gave Max 5 at a time 3 times a day for his allergies, before we got the blood work done and got him the allergy serum. They helped with the itching but never even slowed him down. Another thing to try, if they have raw spots is Listerine. Just dab it on. It will burn a little, but prevents infection and helps to dry it up. It is great for sores and hot spots. Also, the skin scraping is a great idea. Our guys get staph skin infections, from chewing themselves. The vet does a deep skin scraping to diagnose it. We also found out that Cody gets localized demodectic sp? mange. Not contagious, all dogs apparently carry the mites, so no big deal, just treat it with a cream twice a day. However, he does not scratch at the spots or chew them at all. I wouldn't think that is what is causing the itching and chew-o-rama. The foot chewing sounds to me like it could be a contact type of dermatitis. I have had dogs that suffered from athletes foot whenever the weather was changing and occasionally got the same type of rash on their backs from rolling in wet grass or when we had the lawn sprayed. Good luck and kiss those boys for me.
