Last year one of mine got his cut. Took him to the vet they got it put back together. Had to leave it in a cast for 2 months than only light exercise for the next 6 months. You can hardly tell now, dont seem to bother him at all
My vet told me pretty much the same thing. Said he'd be in a cast 2 months also. So once he was out of the cast you just had to keep him in a pen where he couldn't run around on it?
