Activate pet invincibility on existing save games

[mega]

I just started experimenting with pets, and even with heavy baby sitting, they easily die. Mostly, when they have a pathing error (like not finding the way to access your base) they take a big turnaround and get lost, or go into the haze territory etc (which can be interrupted by petting them, where their pathing IA, like a gps, retraces a new route, lol)

Looks like the custom game options, those I wont have access until devs add the ability to change them midgame, have the option to make pets invincible.

Is there any console related or mod related way to do that? Otherwise, for me, the pet feature is kinda useless as it is now (due to pathing errors mostly)
