It's entirly up to you, Your dog pure or not may be the best in your eyes and not in someone elses eyes (if you know what you mean)
My dog is mix and is the best dog in the world to me, may not be to you but she is to me.
See your dog may be the uglyest thing ever yet be the love of your life.
Every dog in the whole world is different, a certain owner of a breed may say, BC are the best breed ever and that their dog can do everything, so you go and get that breed and it will never do the same as their dog,
