A premium or super premium quality food contains all the nutrients and trace elements needed in a puppy, junior, adult or senior Black Russian Terrier. Good food has the correct ratio of all ingredients which ensures optimal growth and body structure.
The Russian Terrier is a heavy, massive dog. During the growth period, it is a good idea to supplement ingredients that support the formation of joint cartilage, i.e:
collagen
hyaluronic acid
glucosamine
chondroitin
MSM
We do not supplement calcium when using a high quality food.
