Optimus was rescued along with a few other dogs from a junk yard area. He is about 55 pounds and is the dad of a couple of other puppies we rescued from the same area. He is a little cautious of new people and would do best in a home with older children . A lot of commotion will make him nervous. He would make a great companion for another dog. Please inquire about meeting him. Birthdate 11/18/07.
