None of commercial diets has enough of it, you have to supplement it

The dose of glucosamine and chondroitin for dogs is about 25mg/kg of BW. So your 20kg dog needs about 500mg. This particular diet has:
Chondroitin Sulfate (min.)* 200 mg/kg
Glucosamine (min.)* 80 mg/kg
This is per/kg of food. So in order for your 20kg dog to get enough of those, it would have to consume about 2kg of food per day. Which would be too much (about 2,2x too much) for an 80kg saint bernard let alone a 20kg dog.
Royal canine joint mobility diet has 1900mg/kg of glucosamine, which means a 1kg of food would be adequate for a 76kg dog, and recommended feeding quantity for a dog of that body mass is about 850g/day. So the diet with the highest content of glucosamine still falls short of daily requirements. Hill's J/D has about 1200mg/kg, so even less.
In my opinion, these diets aren't worth the money. They cost more the regular ones (RC joint is about twice as much as their regular adult dog food) and don't provide enough of necessary supplements.
You're much better off feeding your dog regular diet and adding supplements.
