The vet said that he will likely develop some calcification or scar tissue around it that will be permament. He did show some other arthritis on the same side of his foot, but in the higher joint. No idea what he's doing that is putting more wear on the inside edge of his foot.

I took Dazzle to the vet for a swelling on his toe. It didn't seem to be bothering him in the least (no licking it or limping) even after hard exercise. But it felt hard so I wanted to get it checked. X-rays revealed a small sliver of bone (or maybe arthritis build up) had broken off. It is floating next to the side of his foot and is surrounded by the swelling. I was really surprized at that since even when the vet was moving it around he didn't really react. Since it doesn't seem to be bothering him, he was ok'd for Agility practice and classes.
