Out of these dogs listed what one should i get and why?

Entirely depends on what you want in a dog. How much exercise will you provide daily (a fenced yard is no substitute for exercise out of it)? Ho wmuch grooming are you willing to do? What activities do you want the dog to be able to participate in with you? What is your experience level with dogs? What sort of personality do you prefer? How much shedding can you tolerate? Hiow much time and effort are you willing to invest in training? Do you have other pets and what kinds? Are there children in your home? And so on. A number of the breeds on your list are wonderful with the right owners in the right home, but aren't suitable for the majority of pet homes.
