I've only found dogs useful in Fallout 3 where Dogmeat is my companion through the wastes. Let me explain this:
Fallout 1: Went to Junktown where I was asked to "get rid" of a dog terrorizing some poor man. Hunting rifle away and no dog problem. Obviously this was Dogmeat.
Fallout 2: Found the Pariah DOg which gave me the Jinx perk. Not son funny there either. Let us say that it is extremly annoying, trying to kill Frank Horrigan with guns that explodes all the time.
