My yorkie had this surgery in May of 2010. He's done well. He had to stay overnight at the vet. The fentanyl patch they had on him for pain relief was too much so they removed it the next day. He runs and plays and is pain free. He's 95% functional in that hip although there are times that he operates on 3 feet. Those times are becoming fewer and fewer.
I was told that not doing the surgery would lead to extreme pain and he was very young at the time, only 6 months. It is expensive and there will be rehab exercise involved afterward. I don't regret having it done. Good luck.
