The Chow Shepherd is not a purebred dog. It is a cross between the Chow Chow 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.
"Louie's parents were purebred German Shepherd and Chow Chow. He looks like a little shepherd, the only Chow Chow I see is black spots on his tongue. Louie is 1 year 8 monthes in this picture and weighs 60 lbs and is very slender and tall. Since the day I brought him home, when he was 9 weeks old, he has been go go go. He loves to play, chase things and run. He is very obedient though, which is a plus. I take him to the dog park a few times every week to socialize him. He is very good around other dogs and people. His guarding instincts are also good. He will bark if anyone is around the house/knocking at the door. He is a little bit timid around new people but warms up pretty quick. He is good around other dogs/people. He knows many tricks and obeys them 90% of the time. When I leave the house I don't have to put him in a cage, he never got into the trash or chewed on anything he's not suppose to."
