I know there must be a thread about this somewhere already, but I just can't find it. lol

What is it about a high protein diet that has some people worried? If there are no kidney/liver issues, it is recommended a dog get lots of protein compared to lots of carbs. Their digestive system is not meant to handle carbs such as grains, flours and corn. They become fillers that can cause painful gas, over eating, skin and hair problems and maybe allergies. They wont' cause kidney problems. I just read that senior dogs do much better on no-grain foods.
What I did discover this past week, though, is that the fear of a high protein diet is that the ash content will be too high. If that's the case, it CAN be harmful. Ash is high depending on what type of protein is used. If they grind up too much bone, there will be a higher level of phosphorous and calcium and THAT in turn, can increase ash levels. If there is no bone used, such as in Orijen, then the ash levels are very low so there are no problems.
No, I don't work for Orijen! lol I just happened to read this in the past few days and I thought how much it makes sense.
Carbs, on the other hand, just don't give any nutritional benefit to dogs; puppy, seniors or otherwise. Some isn't a huge problem, but too much and it turns into sugar which then turns into fat. Sure, some can do fine on grains their whole lives. It's different for different dogs, breeds and age groups. I think it's individual, but I do prefer a higher protein diet. 30-40%.
I am looking into the food "Horizon". Does anyone here use it, or know of it? I'm wondering if I should try it out as it is made in Sask. and of great quality, just that they don't use all fresh ingdts. as Orijen does. Most companies don't use fresh, and use frozen which is still fine.
I found this: "Kirk's Veterinary Therapy XIII, Small Animal Practice, page 861, written by Finco, Brown, Barsanti and Bartges "...restriction of protein intake does not alter the development of renal lesions nor does it preserve renal function. Considering these (research) findings, the authors do not recommend reduction of dietary protein in dogs with renal disease or reduced renal function in order to achieve renoprotective effects." They do recommend, though, that once a Blood Urea Nitrogen (BUN) level reaches 75, which is very elevated, that some restriction of protein intake be considered for beneficial effects unrelated to kidney function dynamics. These authors point out that Phosphorus blood levels can play a major role in the health status of dogs with compromised kidney function."
I'd like to hear what others think.
