So exactly how much of the supplements in his kibble is my dog getting per meal?

Chaplin's Merrick's says 800mg Glucosamine and Chondroitin. Does that mean per cup? So if I give him close to 3 cups a day he's kind of getting a lot right? So I don't need to supplement it myself?

Anyone know how distribution of vitamins and supplements work in these foods?

That would be per kilo or 2.2 pounds. I don't know which food you are giving. If it is 125 grams per cup like many kibbles then you are feeding about 375 grams a day which would have about 300mg of each joint supplement. Likely not enough.

Oh yeah, it says "800mg/kg"

I didn't quite get what it meant by that haha, thanks. So yeah, he's really not getting all that much...

I think that determining how much your dog is getting using "natural" sources on food can be a bit tricky. Mostly good-guy bacteria breaks Glucosamine down, but since it happens in the bowel, absorption isn't great. Absorption is best when it occurs in the upper GI tract, rather than the lower.
The issue with relying on bones and cartilage is that so much is simply excreted, and there is no way to determine how much is being absorbed. This is because is bones are digested by bacteria in the bowel.
I would supplement..

How is the analysis of the food different from the analysis of the actual supplements? I hope they aren't just doing the same very rough estimation I did from a not particularly compelling source like this one

but have done their own analysis of the food.

"How is the analysis of the food different from the analysis of the actual supplements?"

It depends on the source they are using, however any company that has the expression in the guaranteed analysis, would have to add that, at a minimum. The question here is more two fold I think. If a manufacturer is using naturally occurring chicken cartilage, the absorption is debated, based on where digestion occurs. For kibbles that add Glucosamine and Chondroitin specifically, although this is the isolated nutraceutical, the ability to add the required level is limited. Absorption is also better when coupled with a probiotic, to ensure a healthy gut.
