The reasons why the dog’s leg suddenly became lame and did not fall to the ground without any trauma may be the following:

< p>Pretending to be lame. Some dogs become lame in order to gain sympathy or achieve certain goals. If the purpose is achieved or the owner observes the dog carefully, it will slowly return to normal.

Calcium deficiency. Dogs who eat a single diet for a long time, have insufficient calcium intake in the body, and exercise a lot, are prone to calcium deficiency, and one of the symptoms of calcium deficiency is limping.

Joint problems. Long-term improper breeding, such as allowing dogs to frequently go up and down stairs, excessive exercise, living in humid environments for a long time, being overweight, etc. These reasons often cause dogs to develop arthritis.

If the dog’s lameness persists, it is recommended to take the dog to the pet hospital for examination and treatment as soon as possible.
