One-year-old puppy Max was adopted from Craigslist in December by Terry Hill and his girlfriend after being found homeless after Hurricane Harvey. <br /><br />The clip, filmed on May 17 in Texas, shows Max getting scared of walking through a partially open door.<br /><br />Terry says: “He's been a great dog, but sometimes we question his intelligence.<br /><br />“His heart is inversely proportional to his brain."<br /><br />Max finds it intimidating to go through doors and often finds himself trapped in a room or closet if the door is not open fully.<br /><br />Finally, after much encouragement and with the bribe of a walk, Max made it through the open door.
