Registered purebred dogs and their owners have always been able to earn titles in obedience, tracking and Earthdog. NAMBR provides the mixed breed dog owner with an equal opportunity to earn titles in these disciplines through NAMBR sanctioned Obedience Trials, Tracking Tests and Earthdog Tests. This compliments activities such as a Flyball and Agility, where there is no distinction between the pure and not so pure bred.

The primary focus of NAMBR is the mixed breed dog, however NAMBR welcomes both registered and unregistered purebreds.
