This dynamic duo, affectionately dubbed the Cheese Pups on Instagram, is obviously not very comfortable with the presence of a new, weird-looking, smelly ornament that has appeared in their home!

At first, they openly try to intimidate the Christmas tree. They give it their best shot to provoke any reaction from the tree, and when that fails, the brothers move a bit closer to get a whiff of that wonderful pine smell. Still utterly confused, they finally get into a mini brawl with each other.
