Cresteds are generally healthy, but like all breeds, they're prone to certain health conditions. Not all Cresteds 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 Cresteds, 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).

• Dental Issues: These tend to crop up due to a genetic link that exists between dominant hairlessness and missing teeth. The Hairless Crested has small, peglike teeth that can slope toward the front of the mouth and cause problems; the Powderpuff has normal toy breed dentition. The Hairless often lose many teeth by the tender age of two or three. Some Hairless require canned food, while others eat kibble with no problem, as does the Powderpuff.
• Progressive Retinal Atrophy (PRA): This is a family of eye diseases that involves the gradual deterioration of the retina. Early in the disease, affected dogs become night-blind; they lose sight during the day as the disease progresses. Many affected dogs adapt well to their limited or lost vision, as long as their surroundings remain the same.
• Legg-Calve-Perthes Disease: This condition involves the hip joint. If your Crested has Legg-Perthes, the blood supply to the head of the femur (the large rear leg bone) is decreased, and the head of the femur that connects to the pelvis begins to disintegrate. The first symptoms, limping and atrophy of the leg muscle, usually occur when puppies are four to six months old. Surgery can correct the condition, usually resulting in a pain-free puppy.
• Keratoconjunctivitis Sicca: Known as "dry eye," it's exactly what the name implies: an inflammation and dry eye. It occurs when there's a deficiency in the water portion of the tear film. The eye becomes dry and the membranes are left with only oil and mucus. The symptoms can be mistaken for conjunctivitis, which also has a gooey yellow discharge. Diagnosis is done with a Schirmer Tear Test. Treatment usually consists of eyedrops and ointment.
