ELI5: Why does all dog food taste horrible?

I consider myself a connoisseur but no matter what dog food I try it just tastes awful. I mean it says "real chicken and beef in gravy" but tastes like a turd and mud mix. Why is it not so simple?

Dogs love the taste of fat, and dry dog food is usually sprayed with a 'flavor enhancing' coating of fat that dogs apparently enjoy. To people, the only flavor it enhances is that of rancid fat.

Also, check the ingredients. Meats not suitable for human consumption are used as pet food ingredients, and that 'cellulose fiber'? It's sawdust.
