What a pretty puppy! May we present Cosmo, Sonia Perez and Brandon Harrell's newest best friend. Cosmo is an Australian Shepherd puppy who was born on January 3, 2009. He is shown here at his Puppy Plan appointment on March 11 when he weighed in at 13.2 happy pounds! Sonia tells us that he is named after Cosmo on Seinfeld - he seems to be a picky eater!
