A dog that is limping but able to run may be caused by trauma, calcium deficiency, joint problems, etc. You need to check whether the dog is injured first, and if it is injured, treat it in time. If there is no injury, then it is calcium deficiency or joint problem. It is best to take the dog to the hospital for examination to confirm the cause.
Tips:
Pay attention to supplementing calcium for dogs at ordinary times, especially during infancy, old age and lactation.
