Tubular

Thankfully, Arthur's not a neurotic chewer. Even as a puppy, he didn't chomp on sofa legs or chair legs (or any legs, for that matter) although he did have a very brief obsession with the mail. What he likes are cardboard tubes. I will give him the occasional toilet paper roll or paper towel roll and he will gnaw it into pulpy mush. And when by some miracle he gets his lips around a wrapping paper tube, well, it's the happiest day of his life.

Sometimes he'll grab the long tube in the center and try to run through doorways. Smack.
