Give me a P....A.....R......K!!!!!!

I went to the park yesterday! It was good as always. My old friend Sophie was there. Last time I saw her she was my size and now she towers over me like a giant! Why to some dogs get big and others stay small like me? And why aren't there more of the small ones around? Melanie says the small ones are the best cause they can sleep in the human beds, and curl up on the couch next to the humans. But sometimes I wonder if the big dogs are somehow better than the small ones. Hmmmm....deep questions to ponder on a Friday afternoon......
