Lowchen: Health

Lowchens are generally healthy, but like all breeds, they're prone to certain health conditions. Not all Lowchens will get any or all of these diseases, but it's important to be aware of them if you're considering this breed.

If you're buying a puppy, find a good breeder who will show you health clearances for both your puppy's parents. Health clearances prove that a dog has been tested for and cleared of a particular condition. In Lowchens, you should expect to see health clearances from the Orthopedic Foundation for Animals (OFA) for hip dysplasia (with a score of fair or better), elbow dysplasia, hypothyroidism, and von Willebrand's disease; from Auburn University for thrombopathia; and from the Canine Eye Registry Foundation (CERF) certifying that eyes are normal. You can confirm health clearances by checking the OFA web site (offa.org).

• Cataracts: A cataract is an opacity on the lens of the eye, which causes difficulty in seeing. The eye(s) of the dog will have a cloudy appearance. Cataracts usually occur with old age and can be treated by surgically removing the cataract.
• Progressive Retinal Atrophy (PRA): A degenerative eye disorder. Blindness caused by PRA is a slow process resulting from the loss of photoreceptors at the back of the eye. PRA is detectable years before the dog shows any signs of blindness. Reputable breeders have their dogs' eyes certified on a yearly basis.
• Patellar Luxation: Also known as "slipped stifles," this is a common problem in small dogs. It is caused when the patella, which has three parts--the femur (thigh bone), patella (knee cap), and tibia (calf)--is not properly lined up. This causes a lameness in the leg or an abnormal gait in the dog. It is a disease that is present at birth although the actual misalignment or luxation does not always occur until much later. The rubbing caused by patellar luxation can lead to arthritis, which is a degenerative joint disease. There are four grades of Patellar Luxation ranging from grade I, which is an occasional luxation causing temporary lameness in the joint, to grade IV, in which the turning of the tibia is severe and the patella cannot be realigned manually. This gives the dog a bowlegged appearance. Severe grades of patellar luxation may require surgical repair.
