The Collie is a gentle, devoted family herder beloved for its grace, intelligence, and famously sweet temperament.
How the Collie coat is built, and what that means when you groom it.
Critical: A Collie should not be shaved.
The undercoat keeps heat out as well as in, and the outer coat shields the skin from sun and insect bites. Clipping the whole coat off removes both. It often grows back patchy, soft or a different colour, and in some animals the guard hairs never return properly. Brush the undercoat out instead of cutting it off.
Caution: A Collie coat mats easily.
Fine or long hair tangles at the base of the coat, out of sight, where the mats tighten and pull on the skin. Brushing has to reach right down to the roots in sections, not just skim the surface.
Information: A Collie drops its undercoat in heavy bursts.
The undercoat comes out in heavy bursts over a few weeks. An undercoat rake, or a bath followed by a proper blow-dry, clears it far faster than daily brushing. Clipping the coat down is not a shortcut for this.
The Collie is a large herding dog from Scotland, known for its gentle nature, intelligence, and strong devotion to family.
The Collie is a large herding breed that developed in Scotland and northern England, where it worked sheep across open hill country. It stands as one of the most recognisable working dogs, partly through its long history on farms and partly through wide exposure in film and television during the twentieth century.
Two varieties exist: the Rough Collie, with its long flowing coat, and the Smooth Collie, which carries a short dense coat. Both share the same build, head shape, and character. The breed is calm in the home, alert to its surroundings, and forms close bonds with the people it lives with.
Collies are gentle, devoted, and intelligent, with a strong reputation for being good with children. They suit owners who can give them regular activity, company, and consistent handling.

The Collie fits active households that want a sensitive, people-focused companion. It does well with families that include children, and tends to stay close to its owners rather than range far. It is less suited to homes where it would be left alone for long stretches, as it values company and can become restless without enough activity or contact.
The Collie originated as a Scottish herding dog and rose to wide popularity in the late nineteenth century, helped by royal interest and later by film.
The Collie traces back to herding dogs kept by shepherds in Scotland and the border regions of northern England. These dogs worked sheep on rough upland terrain, bred for stamina, biddability, and the instinct to gather and move livestock. The name's exact origin is uncertain, with several explanations tied to old words for the dogs or the dark-faced sheep they tended.
For much of its early history the Collie was a working farm dog with regional variation in size and coat rather than a fixed breed. That began to change in the second half of the nineteenth century, when dog showing grew and breeders started to standardise type.
Queen Victoria took an interest in Collies after seeing them on her visits to Scotland, and her patronage raised the breed's profile considerably among the wider public. From the 1860s onward the Collie moved from a purely working animal towards a recognised show and companion breed, and the long-coated Rough variety in particular gained admirers. The Kennel Club recognised both varieties, and the breed standard has remained broadly stable since.
In the twentieth century the breed reached a very wide audience through books, film, and television, cementing its image as a loyal family dog. The two coat varieties, Rough and Smooth, were established and continue to be bred alongside each other today.
The Collie is a large, graceful dog with a long wedge-shaped head, an abundant coat in the Rough variety, and several recognised colour patterns.
The Collie is a large dog of balanced, athletic build with a smooth outline and an air of alertness. The head is a long, smooth wedge that tapers towards the nose, and the muzzle is finished with a flat skull and a defined but moderate stop. The ears are carried semi-erect, with the tips folding forward when the dog is attentive. The overall impression is one of grace and refinement rather than bulk.
| Trait | Detail |
|---|---|
| Height | Roughly 56 to 66 cm at the shoulder |
| Weight | Roughly 23 to 34 kg |
| Coat | Rough variety: long and dense with a full mane and frill. Smooth variety: short, flat, and dense |
| Colours | Sable and white, tricolour, blue merle, and white |
| Eyes | Almond shaped, dark; merles may have blue or part-blue eyes |
The Rough Collie carries a long outer coat with a soft, dense undercoat, a pronounced mane around the neck, and feathering on the legs and tail. The Smooth Collie has a short, hard, flat coat with a thick undercoat and the same body type. Recognised colours include sable and white, which ranges from light gold to deep mahogany, tricolour in black with tan and white markings, blue merle with a marbled blue-grey pattern, and predominantly white dogs with coloured markings. White markings on the chest, legs, and tail tip are typical across all colours. The Kennel Club breed standard covers both varieties under a single entry.
The Collie is gentle, devoted, and intelligent, friendly with family and children, and usually reserved rather than aggressive with strangers.
The Collie has a calm, affectionate temperament and stays closely attached to its family. It is sensitive to the moods of the people around it and responds best to gentle, consistent handling. Harsh correction tends to make the breed anxious rather than cooperative.
With children the Collie is patient and watchful, which accounts for much of its long-standing reputation as a family dog. With strangers it is typically polite but reserved, and may bark to announce visitors before settling once it understands there is no threat. The herding background shows in a tendency to keep track of family members and, in some dogs, to circle or gently shepherd moving children or other pets.
With other animals the Collie usually lives peacefully, particularly when raised alongside them. Its herding instinct can prompt chasing of fast-moving animals, so early socialisation helps shape good behaviour. The breed can be vocal, and some individuals bark readily, which is worth managing from a young age.

The Collie needs regular coat care, daily exercise, and close contact with its family, with the Rough variety requiring more grooming than the Smooth.
The Collie adapts to house or flat life as long as it receives enough daily exercise and company, though it does best with access to a secure garden. It is a people-oriented breed that wants to be near its family rather than kept apart. The thick coat handles cool British weather well; attention is needed in warm conditions to prevent overheating, with shade, water, and exercise scheduled for the cooler parts of the day.
The Collie does well on a complete, balanced diet sized to its large frame and activity level, fed in measured meals to keep a healthy weight.
The Collie should eat a complete and balanced diet formulated for its life stage and size. Adults of this large breed need food that supports steady energy without excess calories, as the breed is moderately active rather than particularly high-energy. Measure portions rather than free-feeding, and adjust amounts to keep the dog lean, with a visible waist and easily felt ribs. Fresh water should be available at all times.
| Life stage | Amount per day | Meals |
|---|---|---|
| Puppy (2 to 6 months) | Per puppy-food label, by weight | 3 to 4 |
| Junior (6 to 12 months) | Per label, adjusted to growth | 2 to 3 |
| Adult | Roughly 250 to 350 g of quality dry food (adjust by brand) | 2 |
| Senior | Reduced to match lower activity | 2 |
Keep treats to about ten percent of daily calories to protect the dog's weight, and use small pieces for training rewards. Most Collies on a complete diet need no supplements, but a vet may suggest joint or coat support for individual dogs. Introduce any diet change gradually over several days to avoid digestive upset.
The Collie typically lives 12 to 14 years and is generally healthy, with a few breed-linked conditions affecting the eyes, hips, and drug sensitivity to watch for.
The Collie is generally a sound, long-lived breed with a typical lifespan of 12 to 14 years. Responsible breeding and routine veterinary care help reduce the breed-linked conditions described below. Buyers benefit from choosing KC-registered breeders who screen their stock for eye and genetic disorders under the Kennel Club's health-testing schemes.
| Condition | Signs | Note |
|---|---|---|
| Collie eye anomaly | Often none visible; detected on eye exam | Inherited; screen puppies early |
| Progressive retinal atrophy | Night vision loss, later full vision loss | Inherited; DNA tests available |
| MDR1 drug sensitivity | Adverse reaction to some common drugs | Genetic test guides safe dosing |
| Hip dysplasia | Stiffness, limping, trouble rising | Screen breeding dogs |
| Bloat (gastric torsion) | Swollen abdomen, retching, distress | Emergency; act immediately |
The Collie is highly intelligent and eager to please, which makes it quick to learn when trained with patient, reward-based methods.
The Collie is among the more trainable breeds. It learns quickly, reads its handler closely, and wants to cooperate, which suits obedience, agility, herding trials, and assistance roles. The other side of that sensitivity is that the breed dislikes harsh handling and may shut down or grow anxious under it. Calm, consistent, reward-based training brings out the best results. Early socialisation to people, places, and other animals helps prevent the breed's natural caution from turning into shyness.
Collies reach breeding maturity in their second year, carry litters for about nine weeks, and raise litters that commonly number around four to eight puppies.
Collies reach physical and behavioural maturity slowly, and responsible breeders usually wait until a dog is around two years old before breeding so that health and temperament can be assessed and screening completed. Females cycle roughly twice a year. Before any mating, both parents should be checked for the breed's known inherited conditions, including eye disorders and MDR1 status, so that affected pairings can be avoided. KC-registered breeders are expected to follow the relevant health-testing protocols.
Gestation lasts about 63 days. Litters vary, with around four to eight puppies being common. Puppies are born helpless, with eyes and ears closed, and depend fully on the dam for the first weeks. Early gentle handling and exposure to household sights and sounds set the foundation for the breed's stable adult temperament. Puppies are typically weaned by around seven to eight weeks and should stay with the dam and littermates until that point to learn normal social behaviour.
| Metric | Value |
|---|---|
| Breeding maturity | About 2 years |
| Cycle frequency | Roughly twice per year |
| Gestation | About 63 days |
| Typical litter size | 4 to 8 puppies |
| Weaning age | 7 to 8 weeks |
| Recommended pre-breeding screening | Eye exam, MDR1, hip evaluation |
