We just got home from the vet. They were closing, so I don't have the write up of the technical terms, but after x-rays, she has shallow hip sockets, with the left being worse, and her knee caps are slipping, also with the left being worse. She has some muscle atrophy because she's been overcompensating on her right. We're going to do pain medication to see if that helps her balance out; they said it's possible muscle tone will straighten out her kneecaps, but she'll probably need surgery. It sounds like hips will be a problem at some point, but she's too young for them to know how badly. The breeder has already offered a replacement puppy pending their own vet's review, and I know it's a costly choice, but I don't think we'd have it in us. So we're going to do meds for a week, consult with an ortho specialist, follow up with our vet on her next shot date in 2 weeks, and go from there.
