Rough Collie

The Rough Collie is a large herding dog from Scotland, recognized by its long double coat, narrow wedge-shaped head, and expressive almond eyes. The breed reached wide public attention through the Lassie films and television series, which fixed its image as a devoted family companion.

Adult dogs typically stand between 22 and 26 inches at the shoulder and weigh roughly 50 to 75 pounds. Despite the size, the temperament is soft. Rough Collies tend to be calm indoors, attentive to family members, and sensitive to tone of voice and household mood.

The breed keeps the working intelligence of its herding background. Collies learn quickly, watch their people closely, and often respond to subtle cues. That same sensitivity means harsh handling tends to backfire.

Who the breed suits

The Rough Collie fits households that can give daily company, moderate exercise, and regular grooming. The breed does well with children and tends to stay close to its people. Owners who travel often or leave a dog alone for long stretches may find the breed's attachment difficult to meet.

The Rough Collie traces back to herding dogs used in the Scottish Highlands and northern England. These working dogs managed sheep across rough, open country, and breeders valued stamina, biddability, and a coat that handled wet, cold weather.

The breed gained royal attention in the 1860s, when Queen Victoria saw Collies during a visit to Balmoral in Scotland and kept several at Windsor. Royal interest raised the breed's profile and helped move it from farm work toward the show ring and companion homes.

The first dog shows of the late 19th century shaped the modern type. Breeders refined the long, narrow head and the heavy double coat, and the Collie was among the breeds recorded in early kennel club registers in Britain and the United States.

During the 20th century the Lassie books, films, and television series carried the breed to a global audience. The fictional dog established the Rough Collie's reputation as a loyal, intelligent rescuer and drove a long period of high demand.

The Rough Collie has a lean, balanced frame built for movement rather than bulk. The head is long and refined, narrowing to the nose in a smooth wedge, and the ears are semi-erect with tips that fold forward. The almond eyes set the breed's gentle, watchful expression.

Coat and colors

The double coat is the breed's most recognized feature. A coarse, straight outer coat lies over a soft, dense undercoat, with a heavy mane and frill around the neck and chest. Recognized colors are sable and white, tricolor (black, white, and tan), blue merle, and predominantly white with colored markings. The coat sheds year round and blows heavily during seasonal molts.

The Rough Collie is gentle and devoted. The breed forms strong attachments to its household and prefers to stay near its people. With children the temperament is patient and tolerant, which is part of the breed's long-standing reputation as a family dog.

With strangers, Collies are usually reserved rather than hostile. Many bark to announce visitors, then settle once the household accepts the newcomer. The breed generally coexists well with other dogs and household pets, helped by a herding background that favors managing rather than confronting.

The breed is sensitive. Rough Collies read tone and mood closely, and they respond poorly to shouting or rough correction. Some lines are vocal, and the herding instinct can show as following or gentle gathering of children and other animals.

Grooming

• Brush the coat two to three times a week, and more often during seasonal shedding.
• Work through the dense areas behind the ears, under the legs, and around the frill, where mats form.
• Bathe every six to eight weeks or as needed.
• Trim nails monthly and check ears weekly for debris.
• Avoid shaving the double coat, which can damage regrowth and reduce insulation.

Exercise

• Provide 45 to 60 minutes of activity daily, split across walks and play.
• Include mental work such as scent games, training, or herding-style activities.
• Use secure spaces, since the herding drive can prompt chasing.
• Adjust intensity in heat, as the heavy coat raises overheating risk.

Environment

The Rough Collie adapts to house or apartment living when given daily exercise and company, though more space suits the size. The breed tolerates cold well thanks to the double coat but needs shade and water in warm weather. The breed does best with regular human contact and can struggle with long hours alone.

The Rough Collie needs a complete, balanced diet formulated for large breeds. Choose a food with a named protein source and feed amounts based on the dog's weight, age, and activity. Because the heavy coat can hide weight gain, check body condition by feel rather than appearance.

Treats and supplements

Keep treats to about 10 percent of daily calories. Many owners support coat and joint health with omega-3 fatty acids, though supplements should be added only with veterinary guidance. Provide fresh water at all times, especially after exercise in warm weather.

The Rough Collie is generally a sound breed with a lifespan of 12 to 14 years. Responsible breeding and screening reduce the most common inherited problems. The breed carries a well-documented drug sensitivity tied to the MDR1 gene, which affects how some dogs process certain medications.

Preventive care

• Schedule annual veterinary checkups and keep vaccinations current.
• Test or confirm MDR1 status and share results with your veterinarian.
• Arrange periodic eye examinations.
• Maintain a lean body weight to protect the joints.
• Keep parasite prevention up to date.

The Rough Collie is intelligent and eager to cooperate, which makes training straightforward for most owners. The breed picks up commands quickly and enjoys having a job. Because Collies are sensitive, harsh corrections tend to cause withdrawal rather than progress, so calm and consistent handling works better.

Basics

1. Start socialization early, exposing the puppy to people, sounds, and other animals.
2. Teach foundation cues such as sit, stay, come, and leash manners.
3. Add structured mental work, including scent games and trick training.
4. Channel the herding instinct into approved games to reduce chasing.
5. Address barking early with clear, consistent responses.

Rough Collies reach physical maturity between one and two years of age, and responsible breeders wait until a dog is fully grown and health-screened before breeding. Gestation lasts about 63 days, and litters commonly range from six to eight puppies.

Before breeding, dams and sires should be tested for inherited conditions, including MDR1 status and eye disorders, so that affected genes are not passed on. Early handling and socialization of the puppies set the foundation for the breed's gentle adult temperament. Puppies usually go to new homes at around eight weeks, once weaned and started on vaccinations.
