My Chewy used to chew her collar off all the time. Maybe I would put them on too lose, I tried to do the 2 finger thing to make sure it was tight but not too tight. She's sneaky, and can find her way into anything, including somehow getting her mouth around her collar. Anyway, she chewed through enough that I finally got her a collar that is really thick and she could never chew through it. That seems to have done the trick.
