Health of the Lancashire Heeler - Patella Luxation
The patella is the equivalent of the kneecap and a luxating patella is one that moves out of its normal location.
It is usually, but not always, found in small breeds. Several affected Lancashire Heelers have been reported lately, some requiring surgery. Although some cases are the result of accidents, most researchers believe it to be inherited, though the mode of inheritance is not known. Hopping or skipping are often indications of patella luxation. Some countries have an official testing scheme and the BVA is examining the possibility of introducing one in this country.
