Ok, I know how passionate people are about their food conversations! LOL So, I hope this stays quite civil because I genuinely am puzzled by some of what I hear. So yes, I am actually going to go there and ask some questions.
It seems to me that quite a lot of people who feed premium foods are using info such as the type at the dog food analysis website. I have read their site and I have some concerns with some of their conclusions.
Now, it really doesn't matter to me what individuals decide to feed their dogs. If your dog is healthy and happy, great! There are several food threads going here. Opinions are a dime a dozen. Now on to my questions:
Corn. Ok, most of us probably agree that grain should not be the top ingredient in foods for an average dog (of course some dogs have special diets and special needs). Dog food analysis cites the inclusion of corn as a bad thing, mentioning that corn is a common food allergy. Well, true enough. But peanuts are the most common food allergy in people, followed closely by shellfish. Strawberries. Tree nuts. And yet peanuts, strawberries, and tree nuts are highly valued and healthy food sources for the vast majority of us who are not allergic. I've also seen mentioned that corn is "not digestible" yet can find quite a lot of scientific studies, actually weighing and measuring poops, that show that corn in the form found in dog foods is very digestible indeed. So, is this conclusion that corn= bad based on actual scientific studies? Or is it more of an opinion?
Grain-free. Again, studies show that grains are highly digestible by dogs. The website I mentioned states that in a "natural state" dogs didn't eat grains. Except the domestic dog as we know him never, ever existed in a natural state. I have yet to see a wild poodle! LOL. Dogs have been domesticated for around 15,000 years. During that time, every breed of dog known to man developed. Man fed dogs, man eats lots and lots of grain. I'm guessing here that, with food scarcity being a common problem up until about 50 years ago in even wealthy societies, most people did not feed their dogs lean cuts of meat and lots of tasty veggies. My guess is dogs got a lot of scraps, and considering the typical human diet those scraps included lots of grains. Remember, the modern dog is purely a creature of captivity, and would have been selectively bred to prosper on whatever food he was getting. So I guess I'm asking again, is there scientific evidence to back up the notion that dogs don't digest carbohydrates?
Finally, that ingredient listing. One of the 6 star foods listed saskatoon berries. Never heard of that, so I looked it up. It turns out it's serviceberry (juneberry). I have two bushes in my yard, and the birds go crazy for them. I'm lucky if I can get a single ripe berry. My guess is in nature, not many fall to the ground. Anywho, my dog walks by the bush frequently and doesn't show much interest (I understand John's dog does!). Seems like it's not high on his list of "natural diet." However, when we go for a walk in the woods, my dog will run a dead line from 50 yards out and find raccoon poop or whatever it is buried in the leaves and scoff it down right quick. LOL. My frantic "Leave it, leave it, LEAVE IT!!!" cries are met with faster swallowing on the part of the dog. My unscientific observation leads me to believe that animal poop is probably very high on the list of an unfed dog's favorite food groups. In small farming communities, I'm guessing cow poop and horse poop was probably quite a common snack for our pets' ancestors. But those saskatoon berries? Not so much.
I know that the antioxidants in berries are excellent for humans, but then we are descended from hunter-gatherer ancestors that likely ate lots of nuts and berries and plants. But did dogs? My dog has learned to like fruits and veggies, but it took him a few times before he figured it out. The first time he saw a piece of bread on the ground, though, he ate it in a hurry. So again, are there long-term studies that show that those particular antioxidants found in fruits help our doggie friends? Are we basing it on what we think is good for us, and assuming similar is good for the dogs? Can dogs successfully extract those nutrients from fruit? I know that dogs will naturally eat a certain amount of plant material if they are allowed to roam.
My biggest question is the big picture one: the "you would not want to eat these things" reference to some of the ingredients in traditional dog foods appeals to emotion. Of course I would not eat them. But my dog can eat poop, drink pond water, swallow worms, and several other gross things with no ill effects. My dog thinks plenty of things are lovely that I find gross. Dogs eat entrails. Dogs eat organs. Yuck and gross, in my opinion, but not the dog's.
I have tried to do research on line, but all I find to back up the claims of the foods is a circular argument where other people say "I have done a lot of research and I have found" and just keep citing back the same few web sites. I guess what I'm looking for is actual scientific studies that back up the claims of this site that quite a lot of what I consider to be high-quality foods are in fact junk.
