Q: I am fostering a dog from the local shelter with a skin infection. Her name is Dakota Johnson, and she looks like an American hairless terrier crossed with fossilized stone. Circular, crusty, sometimes oozing spots are all over her body. And some areas have what look like little pimples. The first two weeks of oral antibiotics, topical antibacterials, and anti-fungal treatment didn’t help. The next two weeks of allergy meds and steroids seemed to be be clearing up the situation. She was scratching less and became interested in eating, and her skin was seeming to heal. But on the third week of giving the steroids every other day things went downhill. New spots have formed, some of them sticky, and a weird smell she had is back. The shelter had a biopsy done and said she had allergies but gave no indication of what she is allergic to. Is there a blood or skin test to find out?
