Colby is a big boy. Every pound of him is full of love and energy! He came in as a stray so we don't know his history. We're still unsure how he is with other dogs and cats, but we would recommend him going to a home without small children. He's shown no signs of aggression towards kids but is truly a tank who hasn't learned yet how strong he is. In his mind, he fits in your lap! We imagine a little one might be easily toppled over when he tries to play with them.
