Life span: On average, St. Bernards live to be about 8 to 10 years old.
Inherited Health Issues: There have been many health conditions associated with the St. Bernard that either occur at an increased frequency within the breed or have a genetic association. Many of these conditions are related to the giant size of these dogs, leading to a variety of orthopedic problems. These conditions may include, but are not limited to, the following: Dilated cardiomyopathy, Callus dermatitis, Pyotraumatic folliculitis, Primary hypoparathyroidism, Gastric dilatation-volvulus, Cranial cruciate ligament rupture, Elbow dysplasia, Hip dysplasia, Osteosarcoma, Panosteitis, Osteochondritis dissecans, Congenital deafness, Idiopathic epilepsy, Cataracts, Dermoids, Ectropion, Entropion, Eversion of the cartilage of the third eyelid, Macroblepharon, Multiple ocular defects with microphthalmia, Prolapse of the gland of the third eyelid and Pyometra.
Preventive Care: Many of the common health problems found in the St. Bernard are related to the giant size of these dogs. Their huge size places additional strain on the joints, which can lead to problems both in young, growing dogs, and mature, adult dogs. It is important to strike a balance between sufficient amounts of exercise, while not overdoing things in growing St. Bernards. Maintaining a healthy body weight is of the utmost importance for these giants. Omega 3 fish oil supplements may also be beneficial for decreasing inflammation within the joints.
St. Bernards are more predisposed to developing a pyometra than other breeds, which is a serious uterine infection. Fortunately, this condition can be avoided by spaying female dogs.
As a deep-chested giant breed, St. Bernards are susceptible to developing gastric dilatation-volvulus (GDV), which is commonly known as bloat. With this condition, the stomach fills with air and/or food, and then flips on itself, preventing the contents of the stomach from emptying. This is a serious and life-threatening condition. A surgical procedure called a gastropexy can be performed to attach the stomach to the body wall, preventing it from twisting. Avoid exercise or any strenuous activity for at least 1-2 hours before or after meals. Feeding two smaller meals per day rather than one large meal can also be beneficial in decreasing the risk of a GDV.
