We have one for cats, let's start one for dogs.

My pup, whenever we give her a Denta-Stick, always carries it in her mouth and whimpers for a while before dropping it on the floor and leaving it there for several hours, and then goes back to chew on it.

Snoopy came up with the idea that lino would be tasty and so he chewed his way through half of it and when you consider that it had only been down for a month. It was of course the very expensive "Cusion Floor" but the daft look on his face was his "Get out of jail free" card and we soon forgave him and blamed each other instead.

We have two Miniature Schnauzers. One of them likes to lie on a little beanbag in the lounge. The other one walks up to it, stands on it, and then rubs his face/nose in it to move it around. We thought he was simply getting confortable before lying on it, but he did this for a few minutes, and then walked off with his beard all over the place! He's done this countless times since, and seems to really enjoy it. He gets into it so much that sometimes he really goes for it and bangs his head on the nearby wall!
