It is very difficult to completely correct it, because it takes you a lot of energy and time, but it is much easier to ease it. First of all, calcium needs to be supplemented. I think liquid calcium is the first choice, because liquid calcium is more easily absorbed. Secondly, after feeding calcium, take it out and sun it for about an hour to help it absorb calcium. Then take it to exercise and run for about an hour every day. In view of your dog's condition, you can take him jogging first. Help its legs get active. Finally, don't feed it with foods rich in vitamin A (such as animal viscera), because taking too much vitamin A will affect and hinder the absorption of calcium. At the same time, you can feed vitamin B 12 and vitamin B 1: both of these vitamins contribute to the absorption of calcium.
If the dog is an adult, you have fed it and found no bad phenomenon, you can feed it. It is best to feed goat's milk if possible, because most animals, including wild animals, can adapt to goat's milk. When feeding calcium, you must feed it according to your weight. Don't feed it too much. If you feed it too much and don't absorb it well, your bones and joints will swell up. Personally, I think calcium supplementation is very important, but absorption is the key, so doing more exercise and sunbathing will help your dog recover soon.
