Well we should have named him Billy because he eats everything (fly swatter, shoes, shoe laces, hats, and ANYTHING else in sight. He is a very hyper dog and is almost a year old. We love him to death though and he is VERY smart. He can get off any chain, leash or collar. He often looks like he's smiling at us. He really loves my kids. He walks around all day whining off and on until they get home.
