This is Cinnamon, she is a Bichon Frise / Shih-Tzu cross (Zuchon, commonly called a Shichon).
Shichons are not a purebred dog. It is a cross between the Bichon Frise and the Shih Tzu. 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. This hybrid cross is recognized by the American Canine Hybrid Club as the Zuchon. It is also commonly called a Shichon by many hybrid breeders. 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.
