I agree with Aly. Each one is different. The combination of the usually sweet tempered lab and the sometimes unpredictable temperment of the Chow (or so "they" say) makes it a case of determining the personality on a pup by pup basis. I know of one lab/chow mix who boards at the kennel I work at. He is the SWEETEST boy! Definitely the lab personalitly predominates. I generally do not presume personality on a breed basis. I have found too many contradicitons to the popular assumption! Can you spend some time with the puppies?? Like Aly said, the way the pup is raised has soooooo much to do with how their personalities are ultimately determined. The pups sound precious! Can you bring Hans to the shelter so see how they get along?? Let us know!!
