Yarn Chewer?

We have a new addition to our family: Marco the Westie. He is the cutest, sweetest puppy you'll ever see! He's 10 weeks old and totally has us wrapped around his little paw:

"Bamboo knitting needles? I thought they were chewy toys!"

A friend wondered if he would fit in my knitting bag. I said that he probably would, but I didn't think the contents would fair well as he is in the chewing stage. The horror of chewed yarn!
