Q. My Chihuahua was jumping and suddenly started whining. Now she won't put her hind leg down, but doesn't cry when I mess with it. Will it heal on own?

A. Leg injuries are very common in small dogs, especially if they have jumped from a high place, or even stumbled and landed on the leg wrong. Leg injuries can be caused by anything from minor sprains and strains, to full blown breaks or joint tears and even arthritis or luxating patellas (knee joints that slip in and out). If the leg appears swollen, dislocated or there is visible bone or bleeding, veterinary care should be sought. Providing strict kennel rest and decreased activity for a day or two can help with minor injuries, however if the limping continues for more than a day you should make an appointment with your local veterinarian.
