I didn't comment to argue either. I commented to educate. Lots and lots of people don't bother reading up on these things so I offer what I learned from my research to you. For free. I'm not telling you you're a bad dog parent. I'm merely telling you Pedigree is crap food, which, of course, you didn't know.
Of course there's a perfect food. Even for humans. We just can't afford it or have the society set up for it to be sustainable or accessible. That doesn't mean that it stops being the perfect food.
Everything is a compromise on value, cost, accessibility, work, and physiology and other factors specific and unique to your dog. Lots of high priced food is crap. Lots of low priced food isn't. If you're trying to go on a compromise on value and cost, it is silly to buy high priced crap food and pretty good idea to buy low cost nutritional food. And it is not a good idea to spend money on crap food when you can spend that same amount on higher quality ones.
But, regardless of all that compromise, crap food will always remain crap food. And that goes for Ramen Noodles. But yeah, cold, freezing temps after a hurricane just blew through the house... you'll find me eating hot Ramen Noodles. I do love the taste of them.
