For all its beauty, the Collie is a worker: that sentence closes the FCI standard’s brief history. Most people think of mane, ruff and gentle eyes. Beneath the coat is a Scottish sheepdog wanting to think and work alongside you.

Origins
According to the standard, Collies probably descend from dogs the Romans brought to Scotland, which mixed with local types. The Rough Collie is a refined version of Scottish shepherds’ working collie, deliberately bred for at least a hundred years. The Smooth Collie (Collie Smooth, FCI No. 296) is the same dog apart from coat length, but has a separate standard. This entry covers the rough variety.
Temperament
Friendly without nervousness or aggression, cheerful and active, good with children and other dogs: that is the standard’s description. Sensitive and attached to family, a Collie withdraws in response to loud harshness.
Exercise and activity
One to two hours’ exercise daily is needed, above all with mental tasks: obedience, tricks, herding practice or mantrailing. Less restless than the Border Collie, but not a dog to lie decoratively in the garden.
Grooming
The dense double coat needs thorough weekly brushing down to the skin, much more often during shedding. Behind the ears and around hind-leg feathering are critical spots. Clipping is not a solution.
Health
Know two concerns. First, MDR1: Washington State University says around 70 percent of US Collies carry the variant, with similar frequencies in France and Australia. Affected dogs may respond to common medicines with tremors, blindness or even death. Only a genetic test gives certainty; record the result in the vaccination booklet. Second, Collie Eye Anomaly (CEA), a congenital developmental defect at the back of the eye: 13 of 16 Rough Collies in a small Italian sample were homozygous for the responsible variant (Marelli et al. 2022). A test exists for this too. Collies reached a median of 13.3 years in the UK analysis, versus 12.0 for crossbreeds, although this combines rough and smooth varieties (McMillan et al. 2024). Read more about MDR1 in the Australian Shepherd entry.
Who is a Collie right for?
Families and active people seeking a friendly companion who enjoys children, likes working together and has grooming firmly in the schedule.
Who should look elsewhere?
People wanting a low-maintenance dog, very loud, hectic households and anyone treating a sensitive dog harshly.
Video: what a Collie really needs
The video shows the Rough Collie as a quiet observer who reads moods and needs calm, structure and trust more than action.
