Anyone here make homemade dogfood?

I know, this is probably a hilarious question considering just how much food pyrs eat, but here’s the thing: Wallace is both picky and also has historically been the gassiest, most nuclear-level farter and getting him onto the money-suck that is Farmer’s Dog has markedly improved matters—far fewer farts (unless he eats dumb things like cardboard) and his poops are so much better. But it’s expensive, and I think I can handle making large batches of rice/meat/frozen veg/eggs, that sort of thing, and make it cheaper than farmers dog (I think…).

I’m wondering if anyone here does this, and if you have a recipe you like, AND if you have a vitamin powder you like.
