The dog and boy in this video are scratching each other’s back. This is one of those amusing moments I’m glad someone caught on camera. I’m guessing that the dog was not intentionally scratching the boy’s back, it’s just a reflex when his tummy is scratched. But the boy’s position is such that he is right in the way of the dog’s scratching leg. On camera, it does look like they are doing some team scratching.
Enjoy this amusing moment.
