How can I be sure that my dog is over sarcoptic mange if there are false negatives? General Dog Discussions
My new puppy tested positive the first time they did an ear scraping. He's been treated for it and his fur has grown back where he lost it and he isn't scratching all the time any more. The vet tested him again and the results were negative. He does scratch sometimes and I know all dogs do but I'm paranoid about it now.
