My 44 LB. mutt is a chewer. I put a padded mat in his crate and he pulled it out and chewed it up. He did that 4 or 5 times to some really nice, brand new mats. Started closing the crate when he wasn't in there because he only chewed the mat after pulling it out of the crate. He didn't like that. I guess I was locking him out of his room. So now there's no mat in there and he goes in and out he pleases.
And look at those EARS ! ! !
