Tyson the German Shepherd / Maltese mix—"Tyson was a Christmas accident; the mother "fluffy" (Maltese) evidentally was in heat and visited family that had a German Shepherd and woila! He is my favorite dog in the whole world!! He is as smart as a German Shepherd and small like a Maltese."
The Sheptese is not a purebred dog. It is a cross between the Maltese and the German Shepherd. 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.
