And it’d make sense compared to actual robots (which are glitchy as all hell both IRL and in lore, and that was before the Cataclysm struck).
I have a pretty good idea of how to make this work (though coding it is out of my reach, most likely). You have a tamed dog in a Pet Carrier and an Autodoc nearby, and then you can make additions to the animal through the use the Autodoc like a crafting recipe.
Perhaps, however, new code should be written to allow bionics to work on dogs and other animals. I don’t know how to apply modifications to a creature like that…
I for one would love a dog that can regenerate and survive attacks from zombies.
