Houston was  abandoned by a companion to the owner and was picked up by animal control.  He is a happy, energetic dog who likes to run in the yard with other dogs. He likes taking long walks and riding in the car. He is crate trained and good in the house.  He will turn without reason and nip I have not found the button that causes this response. He will need a quiet home with an experienced owner. NO KIDS  Judy

Judy's foster update:
Houston and I have been together. He has stopped the nipping with me. I think he is a great dog and needs a strong loving owner to keep him in line.
