I agree. My Vet says the Purina products are the best out of the less expensive brands. My dogs LOVE that Purina One.
It’s also really easy to cook for your dogs, which I also do. Rice, veggies, hamburger (any lean meat, really) cooked down in chicken stock makes a great kibble topping. My dogs love cooked carrots for some reason; gravy or not, LOL!
Homemade dog biscuits are easy to make, too. I have a recipe for making them in the bread machine. Super-easy.
My cats get Iams because it really cuts down on the fur balls and to not put too fine of a point on it, they poop out less because it has no filler. It’s worth the price for that fact alone! I HATE cleaning the catbox but it goes with the territory with indoor cats. *SHRUG*
The Costco brand dog and cat foods are pretty good, I think. First ingredient is chicken, not chicken meal. Good prices, too.
