This dog has been treated for over a year with medicines and shampoos every few days and he is not getting better. He has to wear a muzzle to keep him from biting the sores. The owner (a family member) does not have the money for further treatment. They don't want to put him down, he is a good dog but losing quality of life. Is there anyone or a rescue that can take him and seek further treatment? He is smart and very trainable, goes on walks even without a leash.
