English Setters are generally healthy, but like all breeds, they're prone to certain health conditions. Not all Setters 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 Setters, 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 (HD): 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. 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.
• Hypothyroidism: Hypothyroidism is an abnormally low level of the hormone produced by the thyroid gland. A mild sign of the disease may be infertility. More obvious signs include obesity, mental dullness, low energy levels, drooping of the eyelids, and irregular heat cycles. The dog's fur becomes coarse and brittle and begins to fall out, while the skin becomes tough and dark. Hypothyroidism can be treated with daily medication, which must continue throughout the dog's life. A dog receiving daily thyroid treatment can live a full and happy life.
• Deafness: Deafness is fairly common and can provide many challenges for both the dog and the owner. Some forms of deafness and hearing loss can be treated with medication and surgery, but usually deafness cannot be cured. Patience and time must be given to a deaf dog and there are many aids on the market, such as vibrating collars, to make life easier for you and your puppy. If your dog is diagnosed with hearing loss or total deafness, take the time to evaluate if you have the patience, time, and ability to care for the animal. Regardless of your decision, it is best to notify your breeder so he or she can take steps not to repeat that breeding.
• 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 arthritis or lameness. Your vet may recommend surgery to correct the problem or medication to control the pain. Keeping your dog at a healthy weight also relieves pressure on his joints. How elbow dysplasia will affect your dog is difficult to determine as there are varying degrees of the disease.
