The Bouvier des Flandres is classified by The Royal Kennel Club as a large breed, typically weighing 27–40 kg as an adult, with a median life expectancy of around 11.3 years, according to a 2024 analysis of UK veterinary records by Dogs Trust. Originally developed in Belgium and France to drive cattle and pull carts, the Bouvier is calm, loyal, and protective, with a dense, tousled double coat built to withstand harsh farm weather.
What this means for your Bouvier des Flandres
Hip dysplasia is common given the breed's size and working build, so watch for stiffness or reluctance to exercise as your Bouvier ages. Glaucoma and subaortic stenosis, a congenital heart condition, are also reported in the breed.
Like other large, deep-chested breeds, Bouviers are at increased risk of bloat (gastric dilatation-volvulus) — knowing the warning signs and seeking emergency care immediately can be lifesaving.
When is a Bouvier des Flandres considered a senior?
Under The Royal Kennel Club's size-adjusted guidance, large breeds like the Bouvier des Flandres are generally considered senior from around 5 dog years old.
