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's been tested for and cleared of a particular condition.

In Rhodesian Ridgebacks, you should expect to see health clearances from the Orthopedic Foundation for Animals for hips, elbows, and thyroid and from the Canine Eye Registry Foundation (CERF) certifying that the eyes are normal.

Because some health problems don't appear until a dog reaches full maturity, health clearances aren't issued to dogs younger than 2 years old. Look for a breeder who doesn't breed her dogs until they're two or three years old. The following problems are not common in the breed, but they may occur:

• Elbow Dysplasia is a heritable condition common to large-breed dogs. It's thought to be caused by different growth rates of the three bones that make up the dog's elbow, causing joint laxity. This can lead to painful lameness. Your vet may recommend surgery to correct the problem, or medication and weight loss to control the pain.
• Hip Dysplasia is a heritable condition in which the thighbone doesn't fit snugly into the hip joint. Some dogs show pain and lameness on one or both rear legs, but you may not notice any signs of discomfort in a dog with hip dysplasia. As the dog ages, arthritis can develop. X-ray screening for hip dysplasia is done by the Orthopedic Foundation for Animals or the University of Pennsylvania Hip Improvement Program (PennHIP). Hip dysplasia is hereditary, but it can be worsened by environmental factors, such as rapid growth from a high-calorie diet or injuries incurred from jumping or falling on slick floors.
• Dermoid Sinus is a congenital skin defect in which a cyst or narrow tubelike structure occurs along the spinal area. It can penetrate the skin to varying degrees, and some reach into the muscle tissue and can be attached to the spinal cord. If the dermoid sinus becomes infected it can cause other problems. Some puppies with this defect are euthanized, but others are treated with surgery.
