Annoying Dog

The Annoying Dog has the same look exept the Dog has no mouth (JK) it does have a mouth but it’s closed so much cause the Dog is scared of all the monsters death from Frisk. And later in the game the Dog actually becomes Tistor‘s pet but you can kill the dog. (It’s not a pretty sight) So yeah.

Aperience
The Dog is simple. And looks the same from Undertale 1 but without a mouth. The Dog is extremely fast and gets skinnier over time, this is why you have to feed the dog. With Canned Dog Food.
