If you've had your dog since puppyhood, did you find any or notice when he/she lost baby teeth?
With my old dog I never saw any of his baby teeth fall out.
Just now though my pup, Leroy just lost his first baby tooth and scared the crap out of me in the process lol. I thought he was choking on something because he was scratching at his snout very harshly... turns out he was just trying to get the tooth out lol!
