No. These cheap junk foods don’t actually have any meat in them. They have decomposing slaughter house garbage, soy beans, and garbage swept up off grain milling plants. Sometimes they have fun textured plant-based products imported from China that LOOK like chunks of meat but who knows what they actually are.
Dry Old Roy has zero meat in it. It’s corn and soybeans plus some carcinogenic dyes and preservatives. It’s considered one of the most unhealthy dog foods out there. Oh, and note it does pass the AAFCO standards, which someone mentioned above. They don’t mean anything in regards to quality or healthfulness.
Noting the other replies to your question, I would guess that there can be local regional things your dog should not eat or water which it should not drink.
Maybe bad in one area and not a bad thing in another area? So ask your local vet.
with locally-caught fish, in addition to parasites, there is also the possibility of pollution. There are quite a few localities where they warn people to not eat the fish they catch, or to only eat so many per month.
You (specific) are right that within AAFCO standards, there is a range of quality. That said, the specific is that better foods will have feeding trials and other pet foods will have statements of feed analysis. Information about nutritional adequacy statements. Statement type 1 only mentions “meet nutrient profile”, while statement type 2 mentions the feeding trials. Not all pet foods have the second, as it is more expensive and time consuming.
You (general) can still have a range in quality in these, as again, there is a standard and some may be better than others, but the opposite (foods that do not pass AAFCO standards are better in quality) is not true.
Oh, and I want to point out that slaughterhouse garbage would include the non-muscle parts of the animals, meaning the organs (lungs, spleen, liver, kidneys, bones, GI) that we do not generally consume. And which we’ve just mentioned before ARE needed (because in the wild, they don’t only eat the flank steak or sirloin steak or rump). Even raw food diets and grain-free diets will have them. Again, though, what can vary is the source of them (human-grade vs animal-grade, but in the end, if rendered, it is of little consequence), and the exact proportion (lots of filler with fewer byproducts and muscle is not good, but the opposite is).
