Somebody with more experience please help me with this. Zoey just turned 1 last week and up until a month ago was an amazingly happy energetic little bully. She got some sort of rash so we took her to the vet and figured out it was mites. So they prescribed ivermectin which i have heard can be bad for some dogs but the vet assured me it would be OK. So we started her off with small doses and worked our way up, in the last month she has seemed to become very depressed and can hardly move her back legs. We couldn't stop this dog from leaping onto the couch and running up and down the stairs and now she cant get over the 2in of metal to get in and out of her kennel. I took her to the vet and the vet says it has nothing to do with the medicine and that she has sever hip dysplasia and she need surgery as soon as possible. I don't understand how that could have happened in one month. She weighs 38lbs (she weighed 41lbs when she started taking it) and the vet has her on .73ml oral dose daily. Does this seem right to anybody that has more experience?
