Which dog breed should I get?

Any breed can compete in conformation. You don't seem to have any reason for your list. What you need to do to have is what is your lifestyle, are you experienced with dogs, what type of place do you live in, are you home or gone a lot, etc. Terriers are very stubborn. (All terrier people! I love terriers! I have one! please don't flame me I am trying to give good advice!) Are you going for looks, size? It seems like your are putting thought into your choice though. If you can write back the above information I'm sure that there are many people who can help you pick a good choice for you.
