Gail Mackie of Scotland really loves her dog, Millie, and here's one reason why -- the bullmastiff insists on helping carry the groceries from the car into the house.
Video posted on YouTube shows Millie take the handles of the bags in her mouth and then trot inside.
Mackie's other two dogs aren't as helpful. They're seen in the video, sans shopping bags, walking into the house next to Millie.
And Millie doesn't give up after one bag. She keeps going until the work is done. Even the heavy ones don't stop her!
