The Bulldog (also known as the English Bulldog) is classified by The Royal Kennel Club within the medium ageing band, typically weighing 18–25 kg as an adult despite its short legs. It has one of the shorter median life expectancies of any breed, at around 9.8 years, according to a 2024 analysis of UK veterinary records by Dogs Trust — a reflection of the breed's distinctive, heavily brachycephalic (flat-faced) build.
What this means for your Bulldog
The Bulldog's flat face makes brachycephalic airway obstruction syndrome the breed's defining health concern — laboured breathing, snoring, and heat intolerance are common, and this tends to become more pronounced with age and weight gain. Keeping your Bulldog at a healthy weight and avoiding exercise or exposure to heat during the warmest parts of the day matters throughout life, but especially as they get older.
The breed's facial and body skin folds need regular cleaning to prevent dermatitis, and hip dysplasia is also common given the breed's stocky, heavy-boned build. Because of the flat face, Bulldogs are also considered a higher anaesthetic risk than most breeds, which vets typically factor into planning any procedure.
When is a Bulldog considered a senior?
Under The Royal Kennel Club's size-adjusted guidance, medium breeds like the Bulldog are generally considered senior from around 7 dog years old — though given the breed's shorter typical lifespan, many owners and vets treat this as a fairly firm milestone for stepping up veterinary attention.
