Depending on your playstyle, this might be less important to you. Ranged companions have the benefit of attacking much sooner, so they'll do more damage overtime. He does not have a Companion Perk (passive) that other Companions can have unlocked.The perk 'Attack Dog' gives Dogmeat the ability to pin enemies to the ground, effectively taking them out of the for a short period.Can be used to 'Search for Items', which can be useful for finding missed and hidden loot.Doesn't count as a companion against the Lone Wolf perk, so you can get several good bonuses that other companions will negate.
Less useful if you are a melee character, but still nice to have a distraction.
