If you love dogs then this video of a Bernese Mountain Dog playing with a four week old puppy should bring a smile to face and warm your heart. The puppy is named Gryffin, a Staffordshire Terrier/English Bulldog mix who is a rescue dog. As you can see, he enjoys playing with his big foster brother the huge Bernese Mountain Dog named Eiger. It’s always nice to see a situation in life where the bigger and stronger animal is befriending the smaller and weaker animal.
