Health;
European Great Danes are generally healthy, but like all breeds, they're prone to certain health conditions. Not all Great Danes will get any or all of these diseases, but it's important to be aware of them if you're considering this breed.
European Great Danes are generally healthy, but like all breeds, they're prone to certain health conditions. Not all Great Danes will get any or all of these diseases, but it's important to be aware of them if you're considering this breed.
- Development Issues: Growing problems can develop in puppies and young adults. These are sometimes associated with an improper diet — often a diet too high in protein, calcium, or supplements.
- Hip Dysplasia: This is an inherited 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 others don't display outward signs of discomfort. (X-ray screening is the most certain way to diagnose the problem.) Either way, arthritis can develop as the dog ages. Dogs with hip dysplasia should not be bred — so 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.
- Gastric Torsion: Also called bloat, this is a life-threatening condition that can affect large, deep-chested dogs such as Great Danes. This is especially true if they are fed one large meal a day, eat rapidly, drink large volumes of water after eating, and exercise vigorously after eating. Bloat is more common among older dogs. It occurs when the stomach is distended with gas or air and then twists (torsion). The dog is unable to belch or vomit to rid himself of the excess air in the stomach, and the normal return of blood to the heart is impeded. Blood pressure drops and the dog goes into shock. Without immediate medical attention, the dog can die. Suspect bloat if your dog has a distended abdomen and is salivating excessively and retching without throwing up. He also may be restless, depressed, lethargic, and weak, with a rapid heart rate. It's important to get your dog to the vet as soon as possible if you see these signs.
- Bone Cancer: Sometimes known as osteosarcoma, this is the most common bone tumor found in dogs. It's usually seen in middle-aged or elderly dogs, but larger breeds such as the Great Dane tend to develop tumors at younger ages. Generally affecting large and giant breeds, osteosarcoma is an aggressive bone cancer. The first sign is lameness, but the dog will need X-rays to determine if the cause is cancer. Osteosarcoma is treated aggressively, usually with the amputation of the limb and chemotherapy. With treatment, dogs can live nine months to two years or more. Luckily, dogs adapt well to life on three legs.
- Heart Disease: Heart diseases affect Great Danes; varieties include dilated cardiomyopathy, mitral valve defects, tricuspid valve dysplasia, subaortic stenosis, patent ductus arteriosus, and persistent right aortic arch. Prognosis and treatment vary depending on the specific disorder and the dog's age and general health.
- Surgery: Surgical issues are a bit different for Great Danes than for smaller dogs. For any needed surgery, find a surgeon who is experienced with giant-breed dogs. Ask for a presurgical blood test and ask them to include a clotting profile (this is not part of typical presurgical blood work). In Great Danes, 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).
