DOG

DOG is a robot made by Wrench. He is a giant, gorilla-shaped sentient machine that has the same level of intelligence as a dog. He accompanies the Hallowers as they fight the Combine, and occasionally helps fight. He is nine feet tall and weights three thousand pounds, and is a considerable force to be reckoned with.

Relationships
Wrench - DOG loves Wrench and likes to play with him. He will defend the engineer with his life because Wrench constructed DOG out of scrap metal (and named him DOG instead of DOGM, according to Jared.)

Syl - DOG likes Syl. Syl is one of the few Hallowers (besides Wrench and Mod) that throw scraps for DOG. They have a neutral relationship.

Big - DOG and Big are indifferent. They rarely interact, and when questioned about DOG, Big quoted, "He is big metal thing, and I am a big muscle thing, no?"

Pyro - Pyro and DOG have a slightly unfriendly relationship. DOG hates fire, and Pyro's weapon ''is a flamethrower. ''Pyro is known to dislike robots as well.

Jared - Jared and DOG are indifferent. Jared once stated, "Eh. Wrench's pet projects are fine by me, but it seems he could spend his time better."

Modified - Mod and DOG are best friends. Mod loves to throw scraps, play Ball or even argue for DOG to come along on missions. DOG loves Mod as much as Wrench, and perhaps even more.
