Bud, my chow passed late last year. the pitbull is going to be a good replacement for him as a watch dog. but she has a lot of puppy left in her, so time will calm her down a good bit. i am mixed about chows dogs. I don't think i want another one. I have considered getting another male great dane down the road and breeding him to a pitbull for the puppies. I have seen some pitbull great dane mixes and it can be a very impressive dog. if you have ever seen the monster sized pit's, they breed in great dane and some kind of mastiff to add size, then back breed to pits again to add weight back in. my dane has impressed me in his later years. he is sooo much stronger than the pitbull. he got in a fight last year and i could not restrain him. i am not big, but weigh 180 pounds on a 6 foot 2 frame. he is way stronger than i am.
