one of the things Fritz likes to do is to chew on is empty plastic water bottles.He just can't wait for me to finish drinking them so he can have it.the other I was on the computer and had a water bottle next to me.I heard some growling and then I turned around saw him gowling and his big floppy tail wagging.So,I finished it and I gave it to him and he took it under the couch to chew away on it.It makes an awful cracking noise when he plays with it ,but he enjoys it and tires him out at night.Other times he will sit up and beg and look at me and then I give it to him and he goes to town on itThat's his water bottle story.In case anybody didn't know,fritz is a 2yr old bichon Frise.
