My family is thinking of getting a new dog. We want a large dog that is not very active, and great with kids. We are thinking of a Mastiff or a Great Dane. I also like Doberman Pinchers, but I know they are active. I had two Doberman Pinchers and I think they are great dog, just a little to active then what we are looking for. I was wondering if anyone has had any experience with ether a Mastiff or a Great Dane, or maybe you can recommend a large breed of dog that is not very active and is good with kids?
