I don't think they know yet. He just had the surgery a week ago so the stitches haven't been removed yet and he's still confined to a smaller crate to limit his movement. The Dr. did say something about leaving the pins where they would be easy to remove later but I think that was only if needed.
Poor guy hasn't had a good month. He was just recovering from a black widow bite on his paw that got infected and made him sick. Not 2 days after he finished his antibiotics, he managed to severely dislocate his hip and break the top off his femur.
