Our dogs are amazing! They are loving companions, wonderful playmates, and prolific athletes! Just like people, some dogs just seem born to be strong! Often, those pups whose genetics have gifted with specific traits like extra scent glands, an amazing sight and incredible muscles become working dogs.
