While larger breeds of canines tend to have shorter life expectancy, the life expectancy of the Dogue is still shorter than even breeds of comparable or larger size. According to data collected by the Dogue De Bordeaux Society of America, the average lifespan of the breed is 5 to 6 years. A veterinary database in the UK showed similar figures. In the American survey, the oldest dog in the record was 12 years old. However, the acting dog who played Hooch in the 1989 film, Turner and Hooch, died at the age of 14. The Society is actively recording dogs that are 7 years old or older to celebrate the longer-lived dogs.

Because of its brachycephalic head, the Dogue can be affected by breathing problems. Some may be intolerant of heat or exercise as a result. The brachycephalic head shape can also encourage ectropion—an outward rolling of the lower eyelid which can lead to conjunctivitis (eye inflammation) and bacterial infections. Under the UK Kennel Club's Breed Watch system, the Dogue is classed as a Category 3 breed (formerly High Profile Breed), meaning it is a breed "where some dogs have visible conditions or exaggerations that can cause pain or discomfort."

Aortic stenosis is a disease of the heart valve in which the opening of the aortic valve is narrowed. Symptoms include exercise intolerance, exertional syncope (fainting from physical exertion) and sudden death. One study suggests a high predisposition in the breed. No severe cases were found in adult dogs, and most moderate to severely affected dogs died before one year of age, leading the authors to speculate that the disease is more severe in the Dogue than in other breeds.

Another heart problem in the breed is dilated cardiomyopathy, a condition in which the heart becomes weakened and enlarged and cannot pump blood efficiently. Some affected dogs may die suddenly without showing any signs of problems. Others may die from congestive heart failure after several weeks or months. Affected dogs are often euthanized at an early stage to avoid suffering.

An estimated 5% of dogs may be affected by footpad hyperkeratosis, a thickening of the footpad and sometimes nose. Lesions usually occur at the age of 6 months. X-rays submitted voluntarily to the Orthopedic Foundation for Animals shows that more than 50% of Dogues in the database are affected by hip dysplasia. Over 21% are affected by elbow dysplasia. Approximately 3% of Dogues suffer from retinal dysplasia. Patella luxation affects around 2% of Dogues.

Health

Due to their athleticism and diverse breeding background, the breed tends to be hardy, with an average lifespan of 12 to 14 years, longer than many breeds of a similar size. There are some genetic conditions to be watchful for. The breed tends to suffer from bone diseases such as hip dysplasia, degenerative myelopathy and kneecap dislocation. The breed can also suffer from skin problems, such as mange and skin allergies, because of its short coat. Other health ailments seen in the breed include thyroid and congenital heart defects.

The breed tends to have a higher than average incidence of hip dysplasia. Culling for performance has helped eliminate this problem and others such as patella problems, thyroid dysfunction and congenital heart defects. American Pit Bull Terriers with dilute coat colors have not had a higher occurrence of skin allergies as other breeds. As a breed they are more susceptible to parvovirus than others if not vaccinated, especially as puppies, so vaccination is imperative beginning at 39 days old and continuing every 2 weeks until 4 months old. Then again at 8 months. Once a year after that, as recommend for all breeds.

They are prone to Demodex Mange due to culling for performance. There are two different types of Demodex Mange, namely Localized and Generalized Demodex. Although it is not contagious it is sometimes difficult to treat due to immunodeficiency in some puppies. The localized symptoms are usually loss of hair in small patches on the head and feet of the puppies. This type will usually heal as the puppies grow and their immune systems grow stronger. The second type which is Generalized Demodex mange is a more severe form of the sickness. The symptoms are more severe and include loss of hair throughout the entire body and the skin may also be scabby and bloody. Generalized are usually hereditary due to immunodeficiency genes that are passed on from Sire and Dam to their puppies. A simple skin scraping test will allow the vet to diagnose demodex mange. The most widely used method to treat Demodex Mange is ivermectin injections or oral medications. Since Demodex Mange lives in the hair follicles of the dog, Ivermectin will kill these mites at the source (please consult your vet before taking any action.).
