Julene, Just a thought, but when we first got Holly at 4 mo of age, she was "antsy" at night,...I honestly thought there might have been spiders in the carpet or something else biting her, she was so jumpy. Our vet thought she had juvenile acne because of sores that sound similar to what you see,...on her butt and between her rear legs. Cream didn't help.
Turned out a friend suggested we check her earflaps,....see if they were crusted around the edges,..and they were! Our vet was doubtful about our suggested diagnosis when we called back, but on skin scraping got a mange mite! She had scarcoptic mange and in fact, brought it with her from the breeder, as we were told other pups there were treated for it, when we called to inquire! It is contagious so you never know! Something to consider if things don't clear up with the treatment you've been advised to try. Patti (in Brockville with Holly the new "couch potato girl", Buddy the Aussie (only my front legs, see mom?) and Frosty the crazy ice storm cat (If I wrap my body around the dogs head does it count???)
