I don't know if I'll be able to explain myself right...but I'm wondering if they're trying to get at the fact that canine RDAs (etc) are NOT linear...so smaller breeds who eat, for example, a "normal" kibble may not truly be getting they *should* be getting according to the guaranteed analysis on the bag.
Some companies are now designing kibbles that have, for lack of better description, a denser amount of "nutrition" in a smaller "package" (ie, smaller kibble) -- so that smaller breeds can eat the smaller volume, but still get the necessary requirements. So they may have been trying to get at the fact that perhaps smaller dogs have *not* been getting the guar. analysis and ingredient level of what is on the bag.
It's hard to explain...and I probably didn't do a good job of it...
Dogs are carnivores so their diet should consist of a good deal of protein. I like the higher protein diets for dogs, personally. But, higher protein diets are a concern for a dog who has liver, pancreas, or kidney disease. For a healthy dog though, a higher protein diet is carnivorous. At the end of the day though, you have to find your comfort level for you and your dog.
