Many people consider the long-lived French bulldog to be a much healthier breed of dog than its compact counterparts, but there are still some hazards that need to be taken into account when looking at life expectancy. According to online sources, French bulldogs do not live as long as other breeds, but they should have a good 15 years or more in their life. They are older dogs which means they are less likely to get injured in fights or accidents and can enjoy a more laid-back lifestyle. Many of these dogs tend to have breathing problems, heart conditions, and skin allergies. They are also some of the most likely to suffer from cataracts, which can cause blindness as dog's age. According to the Merck Veterinary Manual, French bulldogs are also prone to developing cancerous tumors like mast cell cancer and hemangiosarcoma. It's not clear how many years after a dog has been diagnosed with cancer it could be expected to live with treatment. The American Kennel Club states that the average life expectancy of a French bulldog is 10 to 13 years. The oldest living dog is currently 24 years old. The oldest living cat is 34 years old.
