Help Branch Get Hip Surgery

Gwen's beloved pup Branch was recently trying to flex on our neighbors dog, as they would often faceoff in each other's respective backyards, barking at a fencepost. We found out today he has arthritis in both hind legs, and this may have led to this result. Anywho, he somehow popped his leg out of the hip socket which requires surgery. If you could help, we would certainly appreciate it.
