The Peanut Butter Gene

I had a couple of Puppy Kongs filled with peanut butter for Rhyn, back when he was new to the house. Alas, he wasn't remotely interested. Almost two months later, 4 months old now, deep in the throes of teething, Rhyn is very interested in the frozen Kong.  I am so happy; peace and quiet and a contented puppy. I really did think he didn't care for peanut butter!
