What are the reasons for a dog's hind leg suddenly going lame?

When a dog's hind leg becomes lame, it may be due to joint problems, injuries, or calcium deficiency. First, check if there are any obvious injuries or punctures on the dog's paws and legs. Then, stroke and press from the dog's waist to its legs, observing for any signs of abnormal pain or resistance. If there is obvious resistance or visible injuries, it's necessary to go to a professional pet hospital for inspection and wound treatment. If the hind leg lameness is caused by a muscle strain, allow the dog to rest slowly. You can also perform some physiotherapy techniques, such as heat therapy and massage.

Arthritis issues:

If the dog shows obvious resistance and the painful area is significantly swollen, and the dog often licks the joint area, it may have arthritis. It is recommended to take the dog to a professional pet hospital for related examinations and active treatment. You can also arrange for some joint-friendly food in the dog's daily diet.

Injury issues:

When a dog suddenly goes lame while walking or playing with other dogs, the first thing to check is whether the dog's paws have been punctured by a sharp object. If there are visible injuries, it's necessary to promptly clean and disinfect the wounds. In cases of severe wounds or large wounds, it's still recommended to go to a professional pet hospital for debridement to avoid infection and inflammation.

Calcium deficiency:

Dogs may also experience sudden lameness due to calcium deficiency and nutritional imbalance. If the dog's body does not absorb enough calcium, it can lead to lameness. Therefore, owners should pay more attention to their dog's calcium intake and arrange for foods or supplements rich in calcium to help the dog acquire calcium.
