William is a 2-3 yr old collie mix. This guy is the bomb! So mild mannered. He is loose and wiggly. He will sit next to his person without being called. He is HIGH energy. He will need a nice fenced in yard to run and play with his person. He pulls on a leash but with some basic obedience, this could easily be resolved. He is food motivated. He knows the "sit" command. He is INTENSELY interested in cats in a shelter environment. We recommend older children due to his energy level.
