The Belgian Shepherd Dog (Malinois) is classified by The Royal Kennel Club as a large breed, typically weighing 20–30 kg as an adult, with a median life expectancy of around 12.0 years, according to a 2024 analysis of UK veterinary records by Dogs Trust. The short-coated, fawn variety of the Belgian Shepherd, the Malinois is prized worldwide for its intelligence, drive, and trainability in police, military, and protection work.

What this means for your Belgian Shepherd Dog (Malinois)

Hip and elbow dysplasia are both reported in the breed given its athletic, working build, so watch for stiffness or reluctance to exercise as your Malinois ages. Progressive retinal atrophy and epilepsy are also seen occasionally.

As one of the most driven working breeds, Malinois can struggle with sudden drops in activity — a gradual, vet-guided reduction in exercise intensity helps ease the transition into the senior years.

When is a Belgian Shepherd Dog (Malinois) considered a senior?

Under The Royal Kennel Club's size-adjusted guidance, large breeds like the Belgian Shepherd Dog (Malinois) are generally considered senior from around 5 dog years old.
