My pet has been scratching like crazy since Mid January. Feb 1st, we brought her to the vet, they told us that she had a puppy acne of sorts, gave us medication and sent us home. 4 Days later, our dog was whimpering so much when she itched.. and the itching was non stop. She has little crusty circle on her ears and parts of her face.. and the more she itched the worse it got. So- they gave us Ivermecin (sp) for Sarcopties Mites.. then2 weeks after that, the itching had resolved a bit, but she was now biting her paws so bad they were bleeding and open. So-- we brought her again to the ER she was placed on Celphlexin (sp) and we were told to continue w/ the Ivermecin....
