Our little pup has a spot on his tail that the vet said was mange. He's had two Ivermectin treatments. The last one was ten days ago. I have been google-ing till my eyes are crossed trying to find out when it will be ok to introduce the pup to the other dogs. They really want to see each other. I'm just not finding good info telling me how to know when it will be ok. He's not trying to bite or scratch and is hair has begun to grow back. So all you vets and vet techs what do you suggest. It was a mild case that we caught before he scratched or got sores on it. . If I can get him to be still enough to get a pic tonight I'll post it.
