Arnold the Weimaraner has terrible separation anxiety, but with the help of Frank as a support dog, he has been able to relax, and has found a best friend.
Watch how cute they are when they sleep and play.
When Arnold was just a pup, the poor dog was mauled by a larger German Shepherd. He was already an anxious dog, but became even more scared and skittish after that.
Then, when Frank came along, he was able to feel comfortable.
