Methods to determine whether a dog’s leg is broken:

1. The shape of the leg. If your dog's legs are shortened, bent, elongated, or other abnormal shapes, it may be a leg fracture.

2. Activities. If your dog's legs flex or rotate abnormally while walking, it may be a leg fracture.

3. Injury. If you can hear the sound of bone rubbing in the injured area, and you can see bleeding, swelling and other symptoms in the injured area, your dog may have a broken leg.

4. Touch the leg bones. Feel whether there is an obvious sense of breakage or dislocation.

5. Film examination. By taking X-rays, you can visually see whether your dog has fractures.

How to deal with a broken dog’s leg:

1. Limit activities. In this case, exercise should be restricted to prevent the dog from suffering secondary injuries and aggravating the condition of the legs.

2. Hemostatic treatment. If the dog's limbs have been separated from the body, it is recommended to send the dog to the hospital promptly to stop bleeding, debridement, and suturing.

3. Postoperative care. If it is surgical treatment, the dog owner should pay attention to the dog's wound care after the operation to prevent the wound from getting infected.
