Tiny puppy hears huge Newfoundland knocking at the door

Rambo, the adorable Cavalier King Charles puppy is a new member of the family.

He has only been with them for a few days, but is happily settling in.

His new family includes a huge Newfoundland dog and Rambo already loves him.

While Rambo is playing fetch outside, Samson, his Newfie brother, barks and shakes the door with his giant paw.

Rambo takes notice and quickly shows mom he would rather play with his brother than play fetch.

Be prepared for a shocking sight when the door opens, Samson looks just huge in comparison to his puppy brother Rambo.

These two mismatches are sure to be best buds.
