Hi, I just wanted to tell you how beautiful those puppies are! The boy on the far left really catches my eye and the litle girl is so small. I have a litter that is 9 1/2 weeks and you will be surprised how much they change in the next couple of weeks. As for showing, I'm not sure anyone can tell you just from looking at a pic but just guess. There are a lot of factors that go into a good show dog including temperament and how the dog carries itself. Personality is a plus!
That said, I hope someone can help you. You might want to post this under the "showing" or "breeder talk" headings. You will probably get more of the answers you want there. Good luck and enjoy that puppy breath!
