The Bearded Collie is classified by The Royal Kennel Club as a medium breed, typically weighing 18–27 kg as an adult, with a median life expectancy of around 13.9 years, according to a 2024 analysis of UK veterinary records by Dogs Trust. Bred to drive sheep and cattle across the Scottish Highlands, the "Beardie" is bouncy, sociable, and famously vocal, hidden underneath a long, shaggy double coat that needs regular grooming.

What this means for your Bearded Collie

Hip dysplasia and hypothyroidism are both reported in the breed, so a slowing gait or unexplained weight gain are worth a vet check as your Beardie ages. Bearded Collies are also one of the breeds more prone to autoimmune conditions such as Addison's disease, which can present with vague, fluctuating symptoms.

Progressive retinal atrophy is seen occasionally, so annual eye checks are worthwhile once your Beardie reaches middle age.

When is a Bearded Collie considered a senior?

Under The Royal Kennel Club's size-adjusted guidance, medium breeds like the Bearded Collie are generally considered senior from around 7 dog years old.
