I understand how concerned you are. It is hard for me to tell, they all look so different at times. How do you feel about the breeder? Do they seem honest, and are they willing to talk to you? I know what you mean about your husband being upset if the puppy isn't full blooded because of the cost. The main thing to me is how you will feel if your puppy turns out to be mixed after he is a puppy no longer, but a grown dog. I read everything I could get my hands on about yorkies before I bought Sawyer. I wanted a yorkie, period. I love their personality, their look, everything about the breed excites me. Yes there are different looks, different personality traits; but they are all different versions of a Yorkie. If you are looking for a little fellow to love, this is one cute guy; but if you have your heart set on a purebreed yorkie, check him out until you feel secure. Too many darling puppies wind up being unwanted adult dogs, and tension between you and your husband, and disappointment in the look of you grown dog can definetly c ause your feelings to change. I think he is a beautiful puppy, but it is still early enough in the game for you to be sure he is what you not only love now, but in the future also. Good luck what ever you decide.
