Most people have terrible perceptions of what it means to be fine. I think most people EXPECT dogs to have smelly and greasy coats. Apparently you think dogs on crappy foods have nice shiny coats, but that has NOT been my experience. Again, this is why I said we need to agree to disagree on this because it looks like OUR perceptions of FINE are different.
Like I said, our Dalmatian Lilly looked fine. She lived to be 10 with no health issues except for renal failure at the very end. I LOVED her, but I HATED petting her because of the greasy film on her coat. I thought that was just how dogs WERE, because I had only known dogs fed crappy foods.
Most people think their dogs are fine on crappy kibbles because dogs are supposed to smell and need to be bathed frequently. They're supposed to fart and have gross poops. They're supposed to shed constantly (obviously some dogs just DO shed a lot). They're supposed to have bad breath. They're dogs.
I think food is a big deal. If you don't think it's important, that is your prerogative.
Their coats felt greasy, they smelled, they felt different than my dogs, they had disgusting frequent poops... and these are hundreds of dogs over the course of a few months.
These dogs were considered fine by the vet too
I'm happy you think that dogs on low quality kibble are just fine, but again, I am in total disagreement with that.
