This distinctive canine results from crossbreeding an Australian Shepherd, a Mountain Dog breed (such as a Bernese Mountain Dog), and a Poodle. The “blue merle” aspect refers to a specific coat pattern characterized by marbled patches of dark pigment on a lighter blue-gray base. This complex genetic inheritance produces a dog known for its intelligence, potential hypoallergenic qualities (inherited from the Poodle), and striking appearance. The varied genetic makeup contributes to individual variations in size, temperament, and coat characteristics.
The increasing popularity of these dogs stems from their potential as family companions. The blend of breeds often results in a trainable and affectionate animal. The intelligence derived from the Poodle and Australian Shepherd lines allows for relatively easy training, while the Mountain Dog influence can contribute to a loyal and protective nature. The blue merle coloring, while aesthetically pleasing, is also a marker for responsible breeding practices, requiring careful consideration of genetic factors to minimize potential health issues associated with the merle gene.
