Recently adopted an English Bulldog. He was fostered from April until August while he was treated for demodex mite infestation and severe anemia. He required multiple transfusions, a lot of care and treatment. His last two skin scrapings were negative and he is healing. He still has a few pustules left that we are going to have the vet check out. He was eating Purina at the shelter, we are transitioning to a lamb and rice blend it is grain free but it DOES have potatoes. I read in a couple of forums that those may cause allergies or increase yeast. His white feet, chest and neck are reddish. I'm not sure how much is due to his healing skin (he was severely consumed with mange and bald over about 60% of his body. Anyone have any clues? I can post pics later when my husband gets home. I am familiar with yeast in humans (I'm a midwife and there is no scaling, flaking or oozing, just a generalized reddness.
