For a large breed over 10 month old, you don’t have to worry about the calcium so much because they are able to regulate their calcium uptake. Being inside the 1:1-2:1 ratio is pretty much for life and all breeds of dog. It is extremely likely that all chicken based dog foods do have glucosamine and chondroitin in them, because they are extremely likely to have chicken cartilage in them. People want to think that only the finest cuts of chicken go into their dog food, and dog food companies want to let them believe that, so they don’t advertise that they just throw in the whole chicken. They only bring up the glucosamine and chondroitin when they can make a plus out of it. It is NEVER a therapeutic amount, even in joint care foods, so if your dogs actually need it, you still need to add it in.
