I do agree with you guys, reps are never to be trusted.. but you can't always deem everyone as liars. What I go on mostly is the product. I tried switching Roz to orijin and acaina(sp?) on two separate occasions. Gave it a full two months to let her system adjust.. non formed stools the entire time! I just know her system processes TOTW perfectly, she has plenty of energy, and her coat and health are wonderful. She is 4 and doesn't have a speck of tartar... but perhaps that is more attributed to the antlers and sun cured raw hides that I get her. Also, when my flat coat was still around, he had terrriibbllee food allergies. Everything I tried just gave him massive hot spots all over his body. Then I found orijin. I switched him to that and it cleared up his skin, but his poops were always terrible. Probably too much protein for my Sr. dog. I was recommended to try TOTW. When I switched to it, none of the skin issues came back and his poops were finally, dare I say, perfect!
So on experience I recommend TOTW.
I think a lot of times when dogs have problems on high end, high protein foods, it's because they are actually getting way too much. It's easy to overfeed, because foods like Orijen are often at least 100 calories more per cup that other foods. Not saying that's what happened her, but that's pretty common.
Also, senior dogs actually need higher protein levels than younger dogs, because their bodies begin losing the ability to absorb as much from their food. I'm always puzzled by "senior dog foods" that are low protein, because that is not what their bodies need!
That said, every dog is an individual and what's works best for your dog is what's best for them.
You say that like there's something wrong with table food! For dogs being fed kibble, a handful of good table scraps on top of each meal was found to be one means to reduce the risk of bloat. Table food is only a bad idea if the person whose table it is eats a lousy diet (processed, starchy, sugary, etc.)... other than that, it is probably the healthiest part of what goes in your dog's dish.
I also think adding in "people food" is great for dogs. With Shanoa, we did have to introduce new foods slowly and in small portions because she had a bit of a sensitive stomach. But she regularly gets things added to her bowl: raw eggs, sardines, cottage cheese, yogurt, either raw or cooked meat...she loves it and it's good for her. It's not every meal, and not all that stuff at once, but human foods that are appropriate (i.e. not dangerous or poisonous) for dogs are great to feed. Just remember to reduce the amount of kibble you feed, or you'll end up with a fat dog.
