My name is Matilda but my family calls me Mattie.  I am an English Mastiff and I was born on May 9, 2007.  I live in Boulder, Colorado.  My mommy just bought another Hale Pet Door since I am getting so big.  I love the freedom it gives me to play in my yard and chase the cat.  SMILE. Guilty doggie pleasure.  I just love the snow here in Colorado and my mommy is glad that the pet door doesn't let the cold in the house.
