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

• Hip Dysplasia: This 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). Dogs with hip dysplasia should not be bred. If you're buying a puppy, ask the breeder for proof that the parents have been tested for hip dysplasia and are free of problems. Hip dysplasia is hereditary, but it can also be triggered by environmental factors, such as rapid growth from a high-calorie diet or injuries incurred from jumping or falling on slick floors.
• Progressive Retinal Atrophy (PRA): This is a degenerative eye disorder that eventually causes blindness from the loss of photoreceptors at the back of the eye. It is not thought to be widespread in Belgian Tervuren. PRA is detectable years before the dog shows any signs of blindness. Fortunately, dogs can use their other senses to compensate for blindness, and a blind dog can live a full and happy life. Just don't make it a habit to move the furniture around. Reputable breeders have their dogs' eyes certified annually by a veterinary ophthalmologist and do not breed dogs with this disease. The eye clearance the breeder shows you should be dated within the past year.
• Elbow Dysplasia: This 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 to control the pain.
• Epilepsy: The Belgian Tervuren can suffer from epilepsy, a disorder that causes mild or severe seizures. Epilepsy can be hereditary; it can be triggered by metabolic disorders, infectious diseases that affect the brain, tumors, exposure to poisons, or severe head injuries; or it can be of unknown cause (referred to as idiopathic epilepsy). Seizures may be exhibited by unusual behavior, such as running frantically as if being chased, staggering, or hiding. Seizures are frightening to watch, but the long-term prognosis for dogs with idiopathic epilepsy is generally very good. Epilepsy can be controlled with medication, but it cannot be cured. A dog can live a full and healthy life with the proper management of this disorder. If your Belgian Tervuren has seizures, take him to the vet right away for a diagnosis and treatment recommendations.
