friendly and gentle with family, children and other dogs
quick to learn and very tuned in to people
loyal, cheerful companion with real herding ability
The outer coat is straight and harsh to the touch, lying over a soft, thick undercoat. A generous mane and frill frame the neck and chest, and the legs and tail carry plenty of feathering, while the face and ear tips stay smooth. The body is balanced and graceful, topped by a refined, wedge-shaped head that gives the breed its gentle expression.62
Colourssable and white (light gold to rich mahogany)tricolour (black with tan and white markings)blue merle (silvery blue with black, plus white markings)white (UKC and AKC; not favoured under the FCI/UK standard)672
Personality what they are like
A kind, even-tempered dog that is happy and active outdoors and settled and calm in the house. Collies bond closely with their people, pick up new things quickly and are sensitive to tone, so they respond best to gentle, reward-based training. Their herding background can show as a tendency to round people up, and a bored collie may become chatty.6247
Daily activity how busy a day looks
Moderate to fairly high: about 45-80 minutes a day of walks, play and mental work. Many collies enjoy herding, obedience, agility and similar dog sports.475
Grooming and care the hands-on bits
The Royal Kennel Club advises daily grooming. Brush through to the undercoat, paying extra attention to the mane, behind the ears and the feathering on the legs and trousers where tangles form; expect heavier shedding at seasonal coat changes.746
Home where they are happiest
Best suited to a home with a secure garden or regular access to open space. Their weather-resistant double coat copes well with cool, wet weather; in warm conditions they need shade and water. They are people-oriented and prefer to live indoors with the family.74
Food basics what goes in the bowl
A complete, balanced diet formulated for large-breed dogs and matched to life stage (puppy, adult, senior), with portions adjusted to keep a lean, fit body condition.4
Company who they like around
Very sociable and family-focused. The breed standard describes collies as getting on well with children and other dogs; they do not like being left alone for long periods.624
The story where it all began
The Rough Collie grew out of the working sheepdogs of the Scottish Highlands, where for centuries these dogs gathered and guarded flocks. The breed standard notes that Roman-era dogs brought to Scotland probably mixed with local types, and that Rough and Smooth Collies share the same roots, differing only in coat length. Collies were first shown in 1860 at Birmingham under the heading 'Scotch Sheep-Dogs', and from about 1870 breeders began to select for looks as well as work. A sable dog called Old Cockie, born in 1868, was widely used and helped make sable and white the favoured colour. Queen Victoria fell for the collies she saw in the Highlands in the 1860s and kept them at her royal kennels, which turned the breed into a fashionable companion. British imports reached the United States from 1879, the financier J. P. Morgan became a leading fancier, and the Collie Club of America was founded on 26 August 1886, one of the oldest breed clubs anywhere. Albert Payson Terhune's 'Lad, a Dog' (1919) and the Lassie films from 1943 onward made the Rough Collie one of the best-known dogs in the world. While Border Collies took over most serious sheep work in Britain, rough collies are still used for herding in parts of Europe and the US.63758

Where the name comes from the story behind it
The breed name 'Collie' is thought to have evolved from dogs brought originally to Scotland by the Romans which then mated with native types, and the Rough Collie is the somewhat refined version of the original working collie of the Scottish shepherd.9
Famous ones stars of the breed
Lassie Famous fictional collie from the Lassie film and television series, known for rescuing people.5
I wake up and stretch, my fluffy coat catching the morning light. My human says 'Good morning, sweetheart' in that soft voice I love. I wag my tail and follow them around the house, making sure everyone is where they should be. After breakfast, we go to the park and I trot happily, keeping my family in sight. I find a stick and bring it back, proud as can be. Later, I curl up on the sofa, my head on a lap, watching the world go by. When the kids come home, I do my happy dance. At bedtime, I sleep at the foot of the bed, guarding my pack with a gentle heart.

Rough Collie tip
For a Rough Collie, choose treats that are low in fat and calories, as this breed can gain weight easily. Offer treats in small pieces and account for them in the daily calorie allowance to keep your dog lean and healthy.
Not veterinary advice. Check with your vet first if your pet has allergies, a health condition, is on a special diet or is pregnant. Treats should stay a small part of the daily food. Cut to a safe size and supervise. Terms of use
Owner questions the things everyone asks
How often should I feed my Rough Collie, and at what times?
Feed your Rough Collie at least twice a day for adults, and three to four smaller meals for puppies, at consistent times each day. Follow the food label and your vet's advice to adjust portions for a lean body condition.411
What should a Rough Collie eat, and which foods are dangerous?
A complete, balanced diet formulated for large-breed dogs is best, matched to your collie's life stage. Avoid dangerous foods like chocolate, grapes, raisins, onion, garlic, and xylitol, as these are especially harmful to dogs.412
How often should I bathe a Rough Collie?
Furry Diary's starting plan suggests bathing every 70 days, but you can bathe more often if your collie gets dirty or has skin issues. Over-bathing can strip natural oils, so aim for at least every three months as a general guide.13Pet Wiki plan
How often does a Rough Collie need brushing?
Daily brushing is recommended by the Royal Kennel Club to keep the dense double coat free of tangles, especially behind the ears and on the feathering. Furry Diary's plan suggests every three days, but daily is ideal during heavy shedding seasons.746Pet Wiki plan
How do I trim a Rough Collie's nails, and how often?
Trim nails when you hear them clicking on the floor, roughly every 28 days according to Furry Diary's plan. Cut a little at a time and stop before the quick to avoid bleeding; if unsure, ask your vet or a groomer for a demo.13Pet Wiki plan
How much exercise does a Rough Collie need?
Your Rough Collie needs about 45 to 80 minutes of exercise daily, including walks, play, and mental challenges. Furry Diary's plan suggests around 60 minutes a day, and they enjoy activities like herding and agility.475Pet Wiki plan
How do I look after a Rough Collie's teeth and ears?
Brush your collie's teeth daily if possible, at least a few times a week, using dog toothpaste. Check ears every two weeks for redness or odor, and clean only the outer ear with a vet-recommended solution, never push anything into the ear canal.13Pet Wiki plan
How long does a Rough Collie live?
Rough Collies typically live between 10 and 14 years, bringing many happy years of companionship.47
Is a Rough Collie good with children and other pets?
Yes, Rough Collies are known for their gentle, even-tempered nature and get on well with children and other dogs. They are very family-focused and thrive in a home with people and other pets.624
Can a Rough Collie be left alone?
Rough Collies are very people-oriented and do not like being left alone for long periods. They prefer company and may become anxious if left too much, so they are best suited to homes where someone is around most of the time.624
