The most common health problems in Old English Mastiffs:

The Mastiff Club conducted a health survey that included 570 dogs. They report that half of the deceased Mastiffs in their survey died before age 7, and three-quarters died before age 10.

  • The most common cause of death in Mastiffs, by far, is cancer, especially bone cancer (osteosarcoma), and also lymphosarcoma.
  • The second major cause of deaths in Mastiffs is bloat, an emergency gastrointestinal syndrome that can kill in a matter of hours.
  • Finally, heart disease is a serious issue in Mastiffs, especially sub-aortic stenosis, cardiomyopathy, mitral valve disease, and occasionally pulmonic stenosis.

As you might expect from their size, orthopedic problems are extremely common in Mastiffs, especially hip dysplasia and elbow dysplasia. The Orthopedic Foundation of America evaluated the hip X-rays of 8230 Mastiffs and found 19% dysplastic. That's bad, and the true rate is even higher because most of the obviously bad X-rays were not sent in for official evaluation. Of 3800 elbow X-rays, 15% were dysplastic – the 14th worst rate of 82 breeds.

Other common orthopedic diseases in Mastiffs include cruciate ligament rupture, panosteitis, osteochondritis, wobbler's syndrome, and occasionally hypertrophic osteodystrophy.

Epilepsy is a serious concern in Mastiffs, especially since it's so difficult to treat in this breed. Most epileptic Mastiffs die by age three.

Urinary infections are common in Mastiffs, and a serious urinary disease called cystinuria is more common in Mastiffs than in any other breed.

The most serious eye disease in Mastiffs is progressive retinal atrophy (PRA), which can occur as early as 6 months old or as late as 3.5 years old, and which progresses slowly to complete blindness in middle age. A simple DNA test is available for PRA in Mastiffs, so you can find out at any time whether your dog has the disease, carries the disease, or is completely clear of it.

Other eye diseases in Mastiffs include cataracts, eyelid abnormalities (ectropion and entropion), eyelash abnormalities, cherry eye, persistent pupillary membranes, and retinal dysplasia.

Hypothyroidism is common in all giant breeds. According to the Michigan State University Thyroid Database, up to 15% of Mastiffs have low thyroid levels.

Skin problems include allergies (which cause itchy skin), demodectic mange, elbow hygroma, non-tumorous growths (sebaceous cysts), and chronic bacterial infections (including severe pyoderma).

Other health issues in Mastiffs include colitis (inflammatory bowel disease), myasthenia gravis, and blood-clotting disease (von Willebrand's).

Can you prevent health problems from happening to YOUR Old English Mastiff?

Yes, often you can.

  1. Some health problems are genetic, which means inherited from parents. Genetic health issues are common in Old English Mastiffs today because of unwise breeding practices. My book, Dog Quest: Find The Dog Of Your Dreams, shows you how to find an Old English Mastiff puppy who is genetically healthy.
  2. Other health problems are environmental – caused by the way you raise your dog. My best-selling dog health book, 11 Things You Must Do Right To Keep Your Dog Healthy and Happy shows you how to prevent environmental health problems by raising your Old English Mastiff puppy (or adult dog) in all the right ways.
