My BC is a HUGE fan of playing with tennis balls and frisbees. I've always noticed that his canines on the top and bottom were a little "dull," but recently it seems like they are getting more and more flattened.
I know he doesn't chew on rocks and there is no fencing in our large yard, which makes me think it could be the toys. However, the frisbee is a Nylabone frisbee, BUT the tennis balls I think have, almost like an asbestos fiber in them, which may be, for all intents and purposes, "sanding" his canines down (yes, he plays with a tennis ball that much - it's like his pacifier).
My question is, at what point should I start, if at all, worrying about how much his teeth are getting flattened? Anyone have any experience with this type of problem.
Thanks in advance!
