Dog Gets Into Viciously Adorable Fight With Doorstop [VIDEO]

It's not exactly Ali-Frazier, but this fight is memorable in its own right.

In this clip, a dog goes at it with a doorstop. It looks like Fido has certainly been training hard because he goes full force, while the door doesn't put up much resistance.

We can only assume the pup retreated to a toilet for some water to hydrate between rounds.
