Dry Kibbles

[Suki Wingy]

What protien percentage am I looking for here?
A bit more information:
Niño's 7 years old, sheds A LOT, hard to make him fat because he only eats what he wants, then runs around a lot.
I think I like Solid Gold Wolfking formula and the Timber Wolf Organic foods the best so far but I need a little help with which formula. If the page says,

A unique formula that may be used for clearing up dermatologic and other conditions caused by adverse food reactions or the buildup of toxins. This formula may also be used for the feeding of animals that require a moderate protein diet because of disease and may be used in the management of canine obesity...
Dakota Bison Canid Formula™ is fully balanced and meets the requirements of all life stages, but we do encourage the adding of meats such as muscle meats, organ meats, sweetbreads

should I maybe look for a different formula for him because he's active and sertainly doesn't need obesity management? If so, my best bet would be Nutrient Dense Lamb, Barley, and Apple Formula or Wild & Natural Dry formula, right? The page about Wild & Natural says,

...is designed for Guard, Military, Police and other Service Dogs, Wolves, Wolf Hybrids, Northern Dogs, kennels, show breeders and other dog enthusiasts who have a need for high levels of nutrients.

Why would we have a need for high levels of nutrients? Is that bad for a dog not working or campaigning?

Southwest Chicken and Herbs sounds very good for Niño, actually. Does anyone know if you can easily swich between the formulas of this brand? The site days somewhere that they reccomend mixing up your dog's diet. If so, I would think having some increased nutrients every once and a while would be a good thing.

My last question (for now) is, Does anyone happen to know of a site where you can enter the numer of pounds per bag and how many cups used per day, and it would give you the number of days the bag would last? That would be really handy.

but will probably try Innova dry next time. She's doing excellent on the CN, I've never seen her healthier.

Orangutango, if she is doing so well on the CN, why are you switching her food?

She gets bored with her food if she eats the same thing day after day and after about a month and a half she just refuses to eat. That, and I believe it's better to give a dog variety and like to rotate foods around. She can handle it easily and prefers it this way too. Feeding kibble, it is difficult to give her variety and this is the only way that I can give her some sort of variety.

Density = mass/volume
Pounds are a measure of mass.
Cups are a measure of volume.
The lbs/cup then depends on the density of a particular kibble.
You can get a ballpark estimate of "kibble density" by weighing a known number of cups of your current kibble. I'm not sure how much kibble density varies (never really considered it), but this method will at least give you some method for estimation.

I don't really have time to get involved with the food discussion right now, but I thought I'd just chime in with this to help you out. Math is your friend.
