We want you to meet two big kids! These are Megan and Will Mendez' girls, Annabel and Missy. Missy is a Bullmastiff puppy who was born on December 18, 2006. She is shown here at her first Puppy Plan appointment on June 19, 2007 when she weighed in at 41.1 pounds. Annabel calls Missy her best friend, and we know that is true. Bullmastiffs are known for their devotion to their owners!
