Are you looking to purchase one of these breeds? You have so many different kinds, with different needs. My personal favorite isn't on that list. I love Shar-pei's, but I can not afford all the surgery they need for their wrinkles, and they are highly prone to skin problems. I had a lab/shar pei mix who was wonderful, I only had him a few years, but he was 16yr when we put him down. I think you need to decide what you want in a dog, how much time you have to devote, and how much extra money you have for grooming or health problems. that would be a good start.
