Boxer Booster
They are generally really good at opening doors. AND he will open the garage door if he finds the button. My boxer before Cortes, Lightning, sometimes stayed in the garage if we were going to be gone, he learned exactly where the garage door button was and would jump up and hit it with his paw and then go visit my grandparents until we got home. We had to put a shield around it where a human could just barely get their finger in there to push it, so beware if he ever spends anytime in the garage.
