It depends on the lameness, if the leg was injured due to falling, collision or being hit by other objects. In this case, your dog may experience pain, swelling, fractures, or dislocations. As you age, your joints may gradually wear down, leading to arthritis. Arthritis can cause pain in dogs and may lead to a limp when walking.

When a dog becomes lame, you must first closely observe its behavior. Pay attention to whether the dog shows signs of pain, such as moaning, licking wounds, etc. At the same time, observe whether the dog shows obvious lameness or abnormal gait when walking. In either case, owners should pay close attention to their dog's health and seek professional veterinary help if necessary.
