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 temperament, intelligence and strong attachment to its family.
Collies developed in Scotland and the north of England, where they worked sheep across open, hilly country. Decades of exposure on television and in film cemented the breed's image well beyond the farm, and it remains one of the most recognisable working dogs anywhere.
Two coat varieties exist within the one breed standard: the Rough Collie, with its long flowing coat, and the Smooth Collie, which carries a short, dense coat instead. Apart from the coat, the two look alike in build, head shape and temperament. Indoors a Collie is settled and easygoing; outdoors it stays alert and watchful.
The breed is gentle, loyal and quick to learn, and it has long had a name for being good with kids. It suits owners who can offer regular exercise, company and steady, consistent handling.

The Collie suits an active household after a sensitive, people-focused dog. It gets on well with kids and tends to stick close to its owners rather than wander. A Collie left alone for long stretches through the working week, in a unit with no one home, is not a good match: the breed wants company and can turn restless without enough to do.
The Collie began as a working sheepdog in Scotland and became widely popular in the late 1800s, helped along by royal favour and later by film and television.
Shepherds in Scotland and the border country kept the ancestors of today's Collie, breeding for stamina and the instinct to gather and move sheep across rough hill country. Nobody is entirely sure where the name comes from; theories point to old words for the dogs themselves or for the dark-faced sheep they worked.
For most of its early history the Collie was simply a farm dog, and type varied a good deal by district. That started to change in the second half of the 1800s as organised dog showing took hold and breeders worked to fix a consistent standard.
Queen Victoria saw Collies on her visits to Scotland and took a liking to them, and royal favour did a great deal to lift the breed's standing with the wider public. From the 1860s the Collie shifted from a working farm dog to a recognised show and companion breed as well, with the long-coated Rough variety drawing particular attention.
Twentieth-century film and television carried the Collie to an even wider audience and fixed its reputation as a devoted family dog. The Rough and Smooth varieties were both established during this period and continue to be bred today.
The Collie is a large, athletic dog with a long wedge-shaped head, a full coat on the Rough variety, and several recognised colour patterns.
The Collie is a large, athletically built dog with a clean outline and an alert bearing. The skull is flat and the head forms a long, smooth wedge that narrows towards the nose, with a moderate rather than pronounced stop. Ears are carried semi-erect, tipping forward when the dog is paying attention. Nothing about the breed's look suggests bulk; the impression is one of grace.
| Trait | Detail |
|---|---|
| Height | Roughly 56 to 66 cm (22 to 26 in) at the shoulder |
| Weight | Roughly 23 to 34 kg (50 to 75 lb) |
| 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 has a long, harsh outer coat over a soft, dense undercoat, with a heavy mane around the neck and feathering down the legs and tail. The Smooth Collie carries a short, flat, hard coat over the same thick undercoat, on an identical frame. Recognised colours are sable and white (ranging from pale gold through to deep mahogany), tricolour (black with tan and white markings), blue merle (a marbled blue-grey pattern), and white dogs with colour patches. White markings on the chest, legs and tip of the tail turn up across all four colours.
The Collie is gentle, devoted and clever, good with children and generally reserved rather than unfriendly around strangers.
Collies are affectionate, even-tempered dogs that stay closely bonded to their family and pick up on mood and tension around them quickly. Handling that is calm and consistent gets far more out of a Collie than anything heavy-handed, which tends to make the breed anxious rather than obedient.
The breed is patient and watchful around kids, which explains a good deal of its long-standing reputation as a family dog. Around strangers it is typically polite but a little reserved, sometimes barking to flag a visitor before settling once it works out there is no threat. The herding background still shows through in some dogs as a habit of keeping tabs on family members, or even gently circling children or other pets as they move about.
Most Collies live peacefully with other animals, particularly when raised together from puppyhood. That said, the herding drive can trigger chasing after anything that moves quickly, so early socialisation matters for teaching good manners around smaller pets. Some individuals are quite vocal, and it pays to get on top of excessive barking while the dog is still young.

The Collie needs regular coat care, daily exercise and close family contact; the Rough variety takes more grooming time than the Smooth.
A Collie settles into house or unit living well enough provided it gets daily exercise and plenty of company, though a secure yard is a real plus. This is a breed that wants to be near its people, not shut away in a laundry or a shed out the back. The dense coat is built for cold, so Australian summers need more care: heat across most of the country runs hot and dry, and a coat suited to Scottish hill country needs shade, fresh water and exercise scheduled for the cooler parts of the day to avoid overheating.
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.
Feed a Collie a complete and balanced diet suited to its life stage and size. As a large breed with moderate rather than high energy needs, adults need food that supports steady output without piling on extra kilojoules. Measure out portions instead of leaving food down all day, and adjust the amount to keep the dog lean, with a waist you can see and ribs you can feel without pressing hard. Fresh water should be down 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 2.5 to 3.5 cups of quality dry food | 2 |
| Senior | Reduced to match lower activity | 2 |
Keep treats to around ten per cent of daily kilojoule intake so they don't crowd out proper meals, and break them into small pieces for training rewards. A Collie on a complete diet generally needs no extra supplements, though a vet might suggest joint or coat support for an individual dog. Bring in any change of diet gradually over several days to avoid an upset stomach.
The Collie typically lives 12 to 14 years and is a generally healthy breed, with a handful of inherited conditions worth screening for.
Collies are a sound, long-lived breed on the whole, typically reaching 12 to 14 years of age. Responsible breeding practices and regular veterinary care go a long way towards keeping the conditions below in check. Buyers are better off choosing breeders who screen their breeding stock for eye disease and other inherited disorders.
| Condition | Signs | Note |
|---|---|---|
| Collie eye anomaly | Often no visible signs; picked up on an eye exam | Inherited; screen puppies early |
| Progressive retinal atrophy | Loss of night vision, followed later by full vision loss | Inherited; DNA tests are available |
| MDR1 drug sensitivity | Adverse reaction to some common drugs | A genetic test guides safe dosing |
| Hip dysplasia | Stiffness, limping, trouble getting up | Screen breeding dogs |
| Bloat (gastric torsion) | Swollen abdomen, retching, obvious distress | An emergency; act straight away |
The Collie is highly intelligent and eager to please, so it picks things up fast when trained with patient, reward-based methods.
Few breeds train as readily as the Collie. It picks up new skills fast, reads its handler closely and genuinely wants to work as a team, which is why the breed does so well at obedience, agility, herding trials and assistance work. That same sensitivity has a downside: a Collie handled harshly tends to shut down or grow anxious rather than fall into line. Calm, consistent, reward-based training gets the best out of the breed, and early socialisation to different people, places and animals keeps its natural wariness from tipping into shyness.
Collies reach breeding maturity in their second year, carry a litter for about nine weeks, and typically raise four to eight puppies.
Collies mature slowly, both physically and behaviourally, so responsible breeders generally hold off until a dog is around two years old before breeding, once health and temperament can be properly assessed and screening is done. Females cycle around 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 at-risk pairings can be ruled out.
Pregnancy runs for about 63 days. Litter size varies, though four to eight puppies is typical. Puppies arrive helpless, eyes and ears still closed, and rely entirely on the dam through the first weeks. Gentle handling early on, along with exposure to the everyday sounds and sights of the home, lays the groundwork for the calm adult temperament the breed is known for. Puppies are usually weaned by around seven to eight weeks and should stay with the dam and littermates until then to pick up normal social behaviour.
| Metric | Value |
|---|---|
| Breeding maturity | About 2 years |
| Cycle frequency | Roughly twice a 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 |

Common questions about the Collie cover size, temperament, grooming needs, lifespan, suitability for families, and where to find one.
The Collie is a large breed, standing roughly 56 to 66 cm (22 to 26 in) at the shoulder and weighing about 23 to 34 kg (50 to 75 lb), with males usually bigger than females.
Yes. The breed is gentle, patient and watchful around children, which is a big part of why it has had such a long run as a family dog. Young children should still be supervised around any dog.
The Rough Collie needs brushing several times a week to stop matting, while the short-coated Smooth Collie only needs a weekly brush. Both varieties shed more heavily during seasonal coat changes.
A Collie typically lives 12 to 14 years. A good diet, regular exercise, healthy weight and routine vet care all support a long life.
Yes. The Collie is highly intelligent and keen to please, so it learns fast with patient, reward-based methods, and responds poorly to harsh handling.
The breed can be vocal and may bark to alert the family or when it is not getting enough to do. Early training and enough daily exercise help keep barking in check.
Look for breeders who screen for inherited eye disease, hip health and MDR1 status, and ask to see health records; reputable breeders are listed through Dogs Australia, the national body for pedigree dog registration. Collie-specific rescue groups are another option.
