Fenway chews everything! Last night he found a baseball in the park and decided to chew on that! He actually chewed to the inside of the ball! There wasn't much left! After that, he decided to chew on a new toy bone I gave him. This morning I looked for it but couldn't find it anywhere! I don't know if he ate the whole thing! He'd chew through a brick if I let him. And he's only 20lbs!
