If you look very closely, you can see a tiny, but very determined dog. We would like you to meet Choco, Sarah Rivera's new baby. Choco is a Chihuahua puppy who was born on January 25, 2007. He is shown here with Sarah and Shannon  on March 30, 2007 at his first Puppy Plan appointment. He weighed in at a whopping 1.6 pounds on this day! Sarah tells us that this cute puppy may be tiny, but he sure THINKS he is a BIG dog!!  What a cutie!
