The Rough Collie β the breed forever associated with "Lassie" β is a large, long-coated Scottish herding dog famous for its elegant appearance, gentle temperament, and remarkable intelligence. Once a working sheepdog in the Scottish Highlands, the modern Collie has become a beloved family companion that retains the breed's defining qualities: devoted attachment, sensitivity, sharp herding intelligence, and a gentle dignified manner. A Smooth Collie variant (same dog, short coat) is a separate breed in many registries.
"Collie" is the old Scottish word for "useful," applied broadly to working sheepdogs of the Scottish Highlands. The modern Rough Collie was developed in the 1800s by selecting larger, more refined herding dogs and crossing in Borzoi for elegance and a longer head. Queen Victoria fell in love with the breed during a visit to Balmoral in 1860; her enthusiasm transformed the Collie from working dog to fashionable companion almost overnight.
The fictional Lassie β created by Eric Knight in his 1940 novel and immortalised in the 1943 film β turned the Rough Collie into an international family-dog icon. Through the 1950s and 60s the breed was among the most popular dogs in the United States. Modern numbers have declined but quality has improved as the breed shifted from mass production back to dedicated breeders.
The AKC recognised the Collie in 1885.
Large, elegant, well-balanced. Males stand 61β66 cm (24β26 in) and weigh 27β34 kg (60β75 lb); females are smaller. The build is athletic but refined β never coarse.
Key features:
Gentle, sensitive, and devoted. The Collie is one of the most family-oriented large breeds β affectionate with its own people, friendly with strangers when introduced calmly, and famously gentle with children. The breed bonds intensely and dislikes being left alone for long.
Collies are intelligent and biddable. The breed retains herding drive β many will gently herd children and pets β but it is rarely intense or problematic.
Vocalisation is moderate. Collies alarm-bark but are not chronic barkers. Most are quiet at home.
The Rough coat is significant work. Brush 2β3 times weekly with a slicker, pin brush, and metal comb, paying attention to feathering, the mane, and the breeches. Daily during the twice-yearly heavy shed.
Smooth Collies need only weekly brushing.
Bathe every 6β8 weeks. Never shave the double coat β it regulates temperature in both heat and cold. Trim hair between paw pads.
Clean ears weekly. Trim nails every 3 weeks. Brush teeth several times weekly.
Moderate to high. Adults need 60β90 minutes of daily exercise β walks, off-leash running in safe areas, training, and play. The breed enjoys agility, herding, obedience, rally, tracking, and scent work.
Collies are athletic but not extreme. They do not need the industrial-scale work that Border Collies or Malinois demand.
Average lifespan is 12β14 years.
Common concerns:
Double-merle puppies have high rates of congenital deafness and blindness. Avoid merle Γ merle breeding.
Adults typically eat 2Β½β3Β½ cups of quality food per day in two meals. The breed maintains lean condition naturally when exercised.
Avoid heavy exercise within an hour of meals (bloat risk). Many Collies are sensitive to dietary changes; transition foods slowly.
Pros
Cons
Not suited for chaotic households, full-time-office homes without coverage, owners unwilling to manage shedding, or those wanting a high-drive working partner.

Do they need a lot of exercise? Moderate β 60β90 minutes daily. Athletic but not extreme. Adaptable to suburban family life.
