P (Problem): I have shown golden retrievers in obedience for quite a few years, and many times your columns helped me out. So when I encountered a problem with a new breed of puppy I bought, I thought of contacting you. I took this new puppy home at eight weeks old, and she is now 10 weeks old. I had the opportunity to let her, play with a littermate--a male taken from the litter when he had just reached seven weeks of age--so they had been apart for three weeks.
