It would be no different than upgrading a robot or giving new weapons and armor to a humanoid companion.

Just cyberdogize him
And that there is a robot that at best has only a dog brain left of its former organic dogginess.
Heh, what I was mainly getting at was that they've done it in a previous game so "we have the technology!". Just convert the armour to a more power armour type and away you go with a tanked up Dogmeat.
Probably can make him like Rex,a cyber dog Police Enforcement or Military.
