A companion dog is a dog that does not work, providing only companionship as a pet, rather than usefulness by doing specific tasks. The American Dirus dog breed is bred specifically and solely as a companion dog breed and nothing more. In order to accomplish this, we have strict criteria for inherited temperament traits in the dogs that go on to give their genes to the ones still to come. Any dog can be a companion dog simply by not having a job, but not any dog breed has what it takes in its genetic foundation to possess the ideal traits needed to be the best companion dog. The American Dirus dog breed is the first large companion dog breed in the world!
