My name is Gizmo!

We are in need of rehoming our 1 1/2 year old dog. We are not sure what breed he is. We believe he is a Greyhound mix. He is super high energy and is very affectionate. He knows a few simple commands like sit and down but he is still learning other commands. He listens to men more than women. He likes to run until his heart is content, dig, and play with toys and sticks. He is not great around small children He is okay around smaller dogs but he does chase cats and birds. He needs a larger place to run and get his energy out. He needs a large back yard or someone who will go out and take him for long walks or to the dog park.
