Ok, here is where I run into problems. hahaha, I love researching diet, whether it be for people or dogs.

This food, Acana, states that carbs aren't important because dogs are adapted to produce energy from meat sources, and aren't really adapted to assimilate starches (carbs), so their extreme formula is low carb (15 or 16%).

But, Momentum, another high performance dog food, states this on their site:

"Momentum uses oatmeal and rice as its primary carbohydrate sources. Oatmeal and rice are both highly digestible and a good source of energy and nutritional balance.

Why include carbohydrates in the diet if fat is the important energy source?

Although fats are a very concentrated energy source, carbohydrates are an important energy source, too. Rice is a highly digestible, easily available energy source and oatmeal is used because of its impact on regulating blood glucose. Blood glucose is the primary energy source for many bodily functions, and there are less blood glucose fluctuations after a meal containing oatmeal than with other carbohydrate sources. Steady blood glucose levels are what we want, hence the oatmeal and rice."

I know, when it comes down to it, I'm just going to go with my gut and what I feel like will benefit Finn. Plus, I will probably switch the kibble every four or five months anyway. but, it's still interesting to read up on the different sites and food out there. I'm trying to learn, hahaha.
