The Blue Spaniel is not a purebred dog. It is a cross between the Australian Cattle Dog and the Cocker Spaniel. The best way to determine the temperament of a mixed breed is to look up all breeds in the cross and know you can get any combination of any of the characteristics found in either breed. Not all of these designer hybrid dogs being bred are 50% purebred to 50% purebred. It is very common for breeders to breed multi-generation crosses.
(Note: the Australian Cattle Dog is also called an Australian Heeler, Hall's Heeler, Queensland Heeler, Blue Heeler, Australian Cattledog and the Australischer Treibhund.)
