We finally got the big dog we have been wanting. This is Brina, which means protector. She is a 7 week old Lab-Bull Mastiff puppy. Her father is a Yellow Lab that weighs over 110 lbs. Her mother is a Bull Mastiff weighing in around 80 lbs. Should grow to be a good size dog! Riley has loved having someone to keep him company. Sam on the other hand isn't so sure!
