Mine do that. They both chew things esp. sticks and leaves into tiny little pieces and chew them for a sec then spit them out on the floor. They are real good about no eating things (except cloth). You should see my house...its aways covered with tiny pieces of stick and leaves...too big for the vaccum so I have to pick them up by hand.
Ya, Petey does that - spits thing out, kappooey!
sometimes he chew things as if they're gum, like his blanket. I wish I could teach him to chew with his mouth closed because it drives me nuts!!
I've had the black Kong for 2 years. It's the only thing he hasn't made any marks in and he loves it - especially at bedtime when I put peanut butter in it.
