Second configuration for my [Panzer Vulpaphyla].
Mod order is important because it determines which actions your pet will priorities in doing.
This build is made for armor strip and a fail safe from Martyr Symbiosis so that my [Nidus] doesn't need to waste his mutation stacks.
For general endless mission gameplay run my other configuration since it provides more utility and keeps your pet alive longer so that it can give you stuff like Fetch and Primed Animal Instinct. If it dies and goes into larva (sentinel) form these two mods won't work. Here's a video of it: https://www.youtube.com/watch?v=g67GsZEvWqM&t=25s .

I used the Zarim Mutagen and Plagen Antigen when crafting my Vulpaphyla which gave me a Naramon polarity and then you get to choose another extra polarity when gilding your pet (after you're done leveling your pet to lvl30 go to son to gild it aka give it a name).
