My Chloe was biting at her butt a few weeks ago, 3 or 4. When I looked at what she was biting at (back leg area) it was all raw, and yucky. Took her to the vet. They called it a hot spot. They took her in back to clean it up. When she came back it was about 6 inches in diameter that they had shaved and was all infected. They said her anal glands were full so they drained them, and that was likely the cause. She was uncomfortable and trying to get as far back as possible, therefore biting on her back leg/butt area. Was given antibiotics and steroids. Ok..I believe i posted about this. But today, same thing, other side. Where it is the most raw, there is no fur, it is bare. But the sore's run down her leg also. I brushed out most of the scab's and she doesn't seem to be biting anymore. But it smells really bad. She didn't do anything unusual yesterday. Could it be anal glands again?? I have been at the vet every week for the past month with one dog or the other. It is getting very expensive. Chloe isn't herself today. Laying around. Not getting up. Don't know what I should do. Should I take her back to the vet? Should I wait and see if it heals on it's own?
