Pet Description: GRINCHY is a 5 and a half month old, 20+ lb, possible boxer/bulldog mix. He has a beautiful marbled spot on his chest and those sad boxer eyes. GRINCHY is a very happy puppy with that wonderful puppy energy. GRINCHY is learning manners with other dogs and people, that normally his momma and siblings would have taught him. He gets so excited when he sees people and doggies that he uses his mouth to get their attention. He tends to push the limits with older dogs, as they don't have the patience to teach him. GRINCHY is short, stout and strong and has learned to sit for treats and body rubs. He also goes into his "house" (crate) when told and receives a treat. This little boy is extremely food motivated and will do just about anything for a treat. He's not the fastest runner but his heart makes up for it. He chases his much larger (and faster) foster sister around the yard but can't seem to ever catch her.
