More: Biscuit is a derpy, lovable Bernese Mountain Dog. At 76 pounds, she’s one of the smallest berners you’ll see but as the runt of the litter, she’s extra feisty and playful. Biscuit was only 7 months when our daughter was born and the two of them have been two peas in a pod ever since. Biscuit takes her guard dog duties very seriously and has been the absolute sweetest and most loving big sister since day 1. She means so much to our family.
