A dog may limp due to several common reasons, including injuries (such as sprains, strains, fractures, or torn ligaments), joint problems (like arthritis, hip or elbow dysplasia), paw issues (cuts, foreign objects stuck in the paw, broken nails), infections (including Lyme disease or paw infections), overexertion, or congenital disorders. Limping can be sudden due to trauma or injury, or gradual due to chronic conditions like arthritis. Observing your dog's behavior, such as licking a paw or avoiding putting weight on a leg, can provide clues to the cause. In many cases, a veterinary examination is necessary to diagnose and treat the underlying cause properly.
