What if the puppy's hind legs are not straight?

The dog's legs are not straight, which is usually caused by its lack of calcium. Dogs with calcium deficiency are generally X-legged or O-legged. Calcium is very much needed by dogs. If the dog is short of calcium, it is easy to get sick in the future, so the dog owner should give the dog some foods with high calcium content, such as laver, shrimp skin, tofu, bones and so on. When cooking, they should put less oil and salt. Eating too much is not good for their health.

There is also that calcium is difficult for dogs to absorb. You can give them some fruits and vegetables after meals, or take them to bask in the sun, which can help them absorb calcium nutrition and is good for their health.

Generally, calcium is given to dogs for a month, and you will know if there is any improvement by looking at your legs. Pay attention to control the amount of calcium supplement, and don't always give calcium to dogs, otherwise it will cause excessive calcium in dogs.
