The idea is simple, equip a melee weapon on Dogmeat and his bite attacks will now deal the same damage (and effects give by mods and legendary status) as the equipped weapon. Let's say I give him a Furious Sledgehammer, for example, his regular bite attacks will now deal the same base damage of the Sledgehammer (23 + Dogmeat's Strength) and deal more damage the more he bites, if I decide to mod the Sledgehammer with a Heavy Searing Sharp Rocket it now deals the additional damage of the mod, burns and targets bleed. I just thought this would be a nice way to make Dogmeat more useful in combat, we have plenty of mods that give him functional armor (My favorite being the K9 Harness) but I haven't seem any that increase his attack, at least not by just simply bumping all dogs base damage.
