French Mastiff Breed Information

French Mastiff   

The French Mastiff, or Dogue de Bordeaux, has a life expectancy of 10 to 12 years.


The true origins of the French Mastiff are unknown. The French Mastiff is believed to have descended from the now-extinct Molossus breed. Numerous dogs developed all over Europe from the Molossus, including one in France. The large French dog was used to fight large animals and later, to protect property and people.

In 1863, one of the large French dogs took home the title at the first Paris Dog Show. The dog was from the Bordeaux area of France and, as a result, the French Mastiff became known, officially, as the Dogue de Bordeaux.  


The French Mastiff weighs 90 to 160 pounds and measures 23 to 27 inches.

Grooming Needs

The French Mastiff has a short, thin coat that just needs to be brushed once a week and bathed when dirty. Like all dogs, the French Mastiff needs basic grooming. Brush their teeth, clean their ears and trim their nails on a regular basis.  


The French Mastiff is courageous and loving.


The French Mastiff looks imposing and intimidating, and is a natural watch dog and guard dog. However, the French Mastiff is not aggressive and likes people. They are steady and even tempered, only springing into action when necessary. The French Mastiff is not one to start a fight, but also not one to back down if provoked.

As is true of many guard dogs, the French Mastiff grows quite attached to their family and has infinite loyalty to them. The French Mastiff is sweet and affectionate with their family and makes an ideal companion. They especially adore children and are very patient with them.

The French Mastiff has an independent steak and can be arrogant. However, the French Mastiff is highly intelligent and wants to please their owner; therefore they can be trained. They respond best to patience, consistency and positive reinforcement. The French Mastiff is quite sensitive and will shut down if treated harshly.

As part of their training, the French Mastiff also needs early socialization. They can be aggressive toward other dogs, especially those of the same sex if not properly socialized.  

Activity Level

The French Mastiff is large, but athletic. The French Mastiff should have a daily walk in addition to regular time outside in a secure area to run and play.
