Methods to prevent joint diseases in dogs:

1. Do not let your dog do strenuous exercise, such as running on a treadmill, frequently going up and down stairs, etc. When you take your dog for exercise, you should pay attention to taking a break in time. Don't let the dog play all the time just because he is very excited.

2. Supplement your dog with enough calcium and eat more foods rich in amino acids and carotene. This can effectively enhance the dog’s bone strength, supplement the nutrients needed for bone and joints, and enhance bone elasticity.

3. Keep the dog’s living environment dry and warm, do not let the dog catch cold, and do not let the dog stay in a cold and damp place.

4. Obese dogs are also prone to joint diseases. Don’t feed your dog too many fatty foods, and control your dog’s weight.

The reasons why dogs suffer from joint diseases:

1. Age. Just like people, the older your dog gets, the more likely he or she is to develop arthritis. Years of joint wear and tear, coupled with the degradation of body functions, make the dog's joint cartilage more and more fragile, and the dog becomes prone to arthritis.

2. Reasons for weight. Excessive weight can compress bones and easily lead to joint disease in the long run.

3. Relapse of old injuries. If your dog's joints have been injured, arthritis may return in a few years.

4. Genetic reasons. If a dog has hip problems, there is a high chance that its offspring will inherit it.
