My dog ​​has O-shaped legs, what kind of food should I give him?

Most of the causes of O-shaped legs in dogs are due to calcium deficiency, and the main correction method is calcium supplementation. You can appropriately add some oil-removed bone soup, egg yolks, and some soy products and other high-calcium foods to your dog's food. You can also give your dog some calcium supplements, such as pet calcium tablets and protein powder, and take your dog out frequently to exercise and bask in the sun.
