The Collie is a large-sized breed. Males typically weigh between 27 and 34 kg when fully grown, while females weigh 23 to 29 kg. With an average lifespan of 12 to 14 years, the Collie is a moderately long-lived breed.
Collie dogs are confident, loyal, and often naturally protective of their families. They are intelligent and trainable, responding best to firm but fair handling. Early socialisation is important to ensure they grow into well-mannered adults. Despite their imposing size, many are gentle and affectionate with their families, including children.
Collie dogs are active and need at least 1-2 hours of vigorous daily exercise. Long walks, hiking, and off-lead running in safe areas are ideal. They have good stamina and enjoy outdoor adventures. Puppies should have controlled exercise to protect growing joints. Mental stimulation through training is also essential.
As a large breed, Collie dogs may be prone to hip and elbow dysplasia, bloat (gastric dilatation-volvulus), and joint problems. Large breeds can also be susceptible to certain cancers and heart conditions. Feeding a large-breed-specific diet during growth helps prevent skeletal issues. Regular veterinary check-ups are essential for early detection of health problems.
Collie dogs need regular grooming including weekly brushing to manage their coat and reduce shedding. Bathing can be challenging due to their size — a walk-in shower or professional groomer may be helpful. Regular nail trimming is important. Check ears regularly, especially if they are floppy, as moisture can lead to infections.
Queen Victoria fell in love with Rough Collies during her stays at Balmoral Castle in Scotland, keeping a kennel of them and showing them at Windsor. Her patronage transformed the Collie from a Scottish working dog into a fashionable companion across Britain and beyond. The breed achieved immortal cultural status through Lassie; Eric Knight's fictional female Rough Collie, first published as a short story in 1938 and adapted into films and a television series that ran for 17 years. Lassie became so embedded in popular culture that the name is now a synonym for loyal canine devotion in the English language.
