I don't know mate I ain't seen your dog. Pm gaz he'll tell you when his bitch broke its toe and didt put its foot down for a week. He just let it calas up and rested her for a while and she's great now. At work we just leave them to calus up if it's the second joint that's broke and keep them off the track for 3 months. If its the first joint( nail end) well have the toe taken off too the joint and rest again. Maybe go see a bone man Robert meek,tom peppercorn only charge a tenner atb mate
