Just because a dog eats more protein or if even a human eats more protein we don't get MORE energy, we just get FAT
Dogs utilize protein and carbohydrates differently than humans. From http://www.thepetcenter.com/imtop/protein.html
Extra carbohydrate intake, above the immediate needs of the dog (which occurs often with grain-based diets) prompts internal enzyme factors to store that extra carbohydrate (sugar) as fat.
Give that same dog extra protein and it is excreted through the kidneys and NOT stored as fat. Knowing this, what do you think would make a better "weight loss diet" for a dog. . . one with grain as the main ingredient or one with a protein-rich meat source as the main ingredient?
My point is that a dog will use protein and fat for energy (resting energy, not just for activity) first, and unless the dog is highly active, will store carbohydrates as fat.
And, as mentioned, small breeds have a faster metabolism than larger breeds. From Yahoo pets, provided by Purina:
Researchers have established that small dogs possess a dramatically different metabolism as compared to large breed dogs, due to physiologic effects of body mass. For example, studies have shown that a Great Dane weighing 100 pounds needs to consume about 23 calories per pound of body weight every day to maintain condition, whereas a 6-pound Pomeranian must take in 47 calories per pound of weight every day - more than twice as much.
This is why you will see "small" breed formulas from many dog food companies such as Purina, Royal Canin, Solid Gold, Artemis, etc... Notice that most have protein/fat levels at and around 28/18.
I do realize that different dogs have different needs, and it is not a one size fits all, but it has been my experience that smaller breeds do much better on a higher protein, low carb diet---good skin and coat, bright eyes, and a more focused energy.
