Brock has had a couple of patches of scabby skin lately that the vet diagnosed as hotspots. A course of antibiotics and the first one cleared up but the second one has flared again. I'm dabbing salt water onto the spot regularly to try and fix it, but my question is, given it's on his lower jaw, is it safe to use betadine? I'm concerned he'll lick the betadine and poison himself. Anyone?
