The protein content really depends upon your dog and your dog's activity levels and how your dog thrives on the food. Royal Canin is a pretty good food. The supplementation of sardines is good because of the Omega acids in the fish, and that is excellent for the joints. I'll give my guys salmon oil, or salmon scraps (skin) from a friend's restaurant.

It's very important to keep a CHD dog as lean and muscular as possible, as the muscling will help hold those joints together.

You might also supplement with a good Vitamin C (Ester C absorbs the best) as that is very good for the joints/soft tissue as well.

Kibbles that contain glucosomine/chondroiten don't usually contain enough of those supplements to do any good, so supplementing with that would be good as well.

Hope this helps.
