I have acquired a female Rottweiler puppy after a three year " dogless" period following the passing of my last female Rott of my breeding at 13 years of age, which ended an almost 20 year span of having a least 1, usually more, of these glorious black beasts around the house. I thought researching and finding a suitable dog food and diet with the net would be a simple task. Not so, it's pretty much overkill on information and opinions, not to mention the multitude of kibbles, dehydrated, frozen etc. on the market now as opposed to 20 years ago.I've always had healthy dogs, no allergys, no bloat, no eating disorders, good coats, good bone and muscle tone. Luck, possibly, but maybe because 1 thing I looked for in purchasing a dog is the health of its parents, and what the longevity characteristics are of it's parents.This was also a main concern when considering breedings. In my mind a lot of disorders that are blamed on diet are genetic disorders. a healthy dog with good function of the intestinal tract Liver, pancreas etc.can get along pretty well on a much less than optimal diet.The pup I have now is on Innova puppy kibble and using the routine I have used many times before, I soften it with chicken or beef broth add add a good vitamin supplement and add an ounce or two of cooked ground chicken, or turkey or ground beef, once or twice a week she gets some egg or her favorite -sardines, with it. She is a healthy active girl, her coat is beautiful, she is at 9 mos. of age already muscular with, as her schutzhund parentage would dictate, very quick, flexible with supurb reflexes, maybe I got lucky again. I'm just happy to have a Black beast sleeping on the floor again.

I don't get what the question is?

I do not see how there would be too much protein in kibble since half or more is grain protein which the dogs have difficulty digesting and end up leaving it in the yard.

Have you looked at the Raw diet?

I think the main Question here is weather too much protein can lead to kidney and pancreas disorders.Since grain is an incomplete protein- Lacks one or more of the essential 12 amino acids- it cannot be used for tissue repair. In the human body if you drink milk , which contains complete proteins, or fish or meat, with grains, cornflakes and milk for instance, the milk has an excess of amino acids to complete the lack of acids in the grain and the grain becomes a complete protein. We have the necessary enzymes to break down grain to a usable form for this process to take place. From an above post I gather amylase, is the necessary enzyme, and if a dog lacks it, grain is useless as a protein source. A question here might be -if a dog is fed grain in a kibble, does the pancreas have the ability to adapt and manufacture amylase,I have read on vet sites that a dog fed only one source of protein will lose the pancreatic enzyme to digest other sources, I wonder if the reverse could be true

That's a bit beyond me!

Here is what I have concluded after a lot of research, and a lot of classes, about dogs being fed a grain-heavy diet on a regular basis:

Yes, the pancreas "tries" to make up for the dog's natural state (which is NOT producing amylase, etc., in amounts sufficient to process daily grain protein) by producing unnatural (to a dog) amounts of these enzymes.

This is (1) not particularly successful; that is, dogs are not equipped to derive their protein from grains; and (2) a stressor on the pancreas, to the point in some dogs of triggering pancreatic derangement (disorder) and even pre-cancerous lesions.

That's the short story, and I'm not a health professional. If you do a "search" here, you'll find that this has been discussed pretty lengthily and with citations.
