Doobie the Jack Russell Terrier / Pekingese mix at 1 year old—"Doobie is an extremely loyal and friendly dog with a distinctive personality. His worst trait is that he gets too excited. He overwhelmingly smothers a person with love when you connect with him, which can be over bearing. He is a lovable dog. "
The Peke-A-Jack is not a purebred dog. It is a cross between the Pekingese and the Jack Russell Terrier. 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.
