Rescue Dog is Very Smart

This dog was rescued and later adopted by me at age 2. He is 4.5 years old in this video and he can sit, shake and do other tricks. He has been DNA tested and is American Pit bull with a small amount of German Shepherd and Chow Chow. He loves to go ch or long walks and his favorite toy is by far a simple green tennis ball. He also loves peanut butter snacks but we don't let him have very often only once in a while as a special treat.
