I see several chow mixes go in and out of the shelter. Of all the lab/chow mixes I've seen, each one was different. If raised properly, I'm sure they'll make wonderful dogs. Chows are one of those breeds that require a little more training than some other breeds. It all comes down to the personality they are born with and the way they are raised. I fell in love with a 6 yr old chow who was the biggest sweetheart in the world. I have also met a 3 yr old chow who spent all three of her years on a chain in a yard and that led to some pretty aggressive behavior. We were able to redeem her though because underneath the agressiveness she turned out to be a big softie. I guess my point is dogs are like humans, each with different personalities. The breed can alert you to be aware of certain things but when it comes right down to it, you just have to spend time with the individual to figure out his/her exact temperment.
