You won't find the NASC seal on many pet supplements. I use a few that I trust that use "human grade" ingredients, but if I decide to add something to our dogs raw diet I usually choose to use human supplements.
Wholistic Pet Organic's is a good, reliable company for supplements.
I personally, would not use Cosequin due to some of the ingredients such as "Yellow #5 or Sodium Lauryl Sulfate" in several of their products.
A couple of raw chicken feet a few times per week should do the trick for natural Chondrotin/Glucosamine! You can order frozen chicken feet from here:

or

If you prefer a joint supplement this is a good one that I've used for my dogs and myself!

I feed sardines or salmon 3 times per week and raw eggs 3 times per week. My raw meat mix contains a percentage of raw/pulverized vegetables.
Vegetables and fruits should be pulverized in a blender to break them down for absorption/digestion, otherwise you'll probably see most of them come out whole in their stool! (you'll need to add some purified water for mixing)
An easy way is to make up a batch, put your mix in ice cube trays and freeze. You can use one or two cube's per meal, but, always begin with small amounts, taking a few day's to see how these new additions will effect their gut. If stool gets loose, go back to previous amount fed (where stool was solid) and hold at that amount for a few days until his gut gets use to it. Then increase again. This is called "bowel tolerance".
Note that green beans, need to be "blanched" or slightly cooked before pulverizing/feeding. Also, not too much higher sugar content veg & fruit's such as carrots/apples. I use dark green lettuce and other colorful vegetables.
Rotation of supplements and vegetables are key!
