About a week ago she started limping and having trouble getting up/laying down. We were keeping an eye on her and she seemed to be getting better, but just to make sure it wasn't anything serious, I took her to the vet on Friday. Turns out she had a sprained ACL, which will heal on it's own with minimal exercise, but I also had them do x-rays on her hips and they didn't look so great. The vet noticed she was already showing signs of possible hip dysplesia. She couldn't say if it will get worse, or when, she just pointed out the signs. The only thing we can do right now is give her glucosamine supplements and keep getting her x-rayed once a year. Poor girl though - she's not even a year old. No weight pulling for her.
