I Cannot believe the nerve of my puppy. i feed him i walk him he jumps on me weely neely and then yesterday we are relaxing and i rest my foot on his back n he growls. My GF tries it and he tries to snap at her. i figured he is tired so i tried again today still doing the same thing growling and snapping and eventually he just walked away from me. i did a body check to make sure he is not in pain or bruised but am like at a loss. Any Ideas??
