Theo's underbite just adds to his cuteness! Theo is a super sweet terrier mix who weighs in at 10.8 pounds. This little guy has the best personality and is happy to meet new friends and visit with old friends. Theo gets along fabulously with the other small dogs in his foster home. They are small dogs like him. We would love to tell Theo he gets to come to Wisconsin on February 10th. He just needs an approved adopter!
