Dozer here! He is a 8 month old. He is so smart that he already knows sit, paw, down and crawl. He is neutered, microchipped, and current on vaccines. All he needs is a family. This picture is from the Lure course at pet value. He loves to run, likes hikes and water. He needs an active family. He gets along best with female dogs his size. He did great in the challenge!! ABSOLUTELY POSITIVELY NO YOUNG CHILDREN. TEENAGE IS FINE. IF CHILDREN VISIT HE MUST BE CRATED IMMEDIATELY.
