Grooming guidance

  • Critical: A Smooth 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.

  • Information: A Smooth 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.

About the Smooth Collie

The Smooth Collie is a medium-sized herding dog from Scotland with a short, flat coat, well suited to New Zealand's active outdoor lifestyle and cooler winters.

The Smooth Collie is the short-coated branch of the Collie family, sharing the same frame, temperament, and working background as the Rough Collie most people picture when they hear the breed name. Coat length is really the only point of difference. Kennel clubs around the world handle the split differently: some register Smooth and Rough as one breed with two coat types, others list them apart.

Farmers in the hill country of Scotland and northern England bred this dog to handle sheep across open, exposed ground, terrain not unlike parts of the South Island high country. It carries the watchful, ready manner of a working dog, paired with a settled and affectionate nature once it is off duty. Smooth Collies attach themselves firmly to their household and do not tend to wander far from their people.

The smooth coat lies flat and dense rather than long and flowing, so upkeep is far less demanding than for the Rough variety. It stays an active, sharp-witted dog that does best with a daily walk or run and a family willing to give it a job, even if that job is only a game of fetch in the paddock.

Who it suits

The Smooth Collie suits active households that can offer a daily walk, a run, or time at the local dog park, plus steady company. It is a sensitive, people-focused dog and does not do well left alone for long stretches while everyone is out at work or school. Owners keen on training, agility, or a spot of casual herding will find it quick on the uptake and eager to join in.

History and origin

The Smooth Collie developed as a working sheepdog in Scotland and northern England, sharing its origins with the Rough Collie before the breed's popularity spread worldwide in the 19th century.

The Collie's roots lie in the hill country of Scotland and northern England, where farmers needed a dog tough enough to handle sheep over rough, exposed ground. Long before anyone kept formal breeding records, working dogs of this type earned their place on stamina, herding sense, and a willingness to take direction, not on looks.

Smooth and Rough Collies share this working history. In the early days, smooth-coated and rough-coated pups turned up in the same litters and did the same jobs on the farm. The smooth coat became linked with droving, walking stock long distances to market, while both coat types worked sheep at home.

Interest in the breed spread well beyond the farm gate during the 19th century, helped along by show ring appearances in Britain and by royal favour in the Victorian era. Selective breeding sharpened the type, and the Collie became an established, recognised breed.

The breed later travelled with settlers to countries including New Zealand, where working collies took readily to mustering sheep across high-country runs. Registration practice still varies by country: some list Smooth and Rough as varieties of a single breed, others register them separately.

Appearance and breed standard

The Smooth Collie is a medium-sized, balanced dog with a wedge-shaped head, a long muzzle, and a short, flat, dense coat that comes in several recognised colours.

The Smooth Collie carries the same outline as the Rough Collie: a medium-sized, well-balanced dog with a level back, a deep chest, and a long, lean head that narrows to a fine muzzle. The expression is alert yet gentle, and the ears sit semi-erect, tipping forward when something catches the dog's attention.

The coat is what sets it apart. Rather than the long outer coat of the Rough variety, the Smooth Collie has a short, flat, hard topcoat over a dense undercoat. The result is a sleek line that follows the body closely and is simple to keep tidy.

Coat and colours

Recognised colours include sable and white (shades from gold through to mahogany, with white markings), tricolour (black with tan and white), blue merle (a marbled blue-grey with black patches), and mostly white dogs carrying colour patches. The short coat sheds year-round with a heavier blow twice a year, but it will not mat the way a long coat can.

Temperament and personality

The Smooth Collie is gentle, loyal, and clever, generally good with kids and other animals while staying alert and watchful around strangers.

The Smooth Collie has an even, gentle temperament that has made it a long-time favourite family dog. It bonds tightly with its household and is usually patient and dependable around children. Genuine aggression is not typical of the breed.

Around strangers it tends to hang back and watch rather than react. It is alert and will bark to flag visitors or anything out of the ordinary, a habit left over from its herding days. Good socialisation from puppyhood helps it meet new people, places, and situations with confidence rather than suspicion.

Most Smooth Collies get on well with other dogs and household pets, especially if raised together. Some individuals keep a strong herding streak and may try to round up or trail after moving kids or animals in the backyard. This is a clever, sensitive dog that does best in a calm household with clear, kind handling, and it can turn anxious or noisy if left home alone for long periods.

Care and grooming

The Smooth Collie is straightforward to look after, needing a weekly brush, a daily walk or run, and plenty of company as a people-focused breed.

Grooming

  • Brush weekly to clear loose hair and keep the undercoat in good condition.
  • Step brushing up to several times a week during the seasonal blow.
  • Bath only when needed; the short coat stays clean with little fuss.
  • Trim nails every few weeks and check ears regularly.
  • Brush teeth a few times a week to keep on top of dental health.

Exercise

  • Aim for at least 60 minutes of activity a day, split between walks and play.
  • Let it run off lead in a safe, fenced area when you can.
  • Add mental work such as training games, scent games, or a solid game of fetch.
  • Look into dog sports like agility, obedience, or herding trials; several clubs run these around the country.

Environment

The Smooth Collie settles into town or country life as long as it gets its daily exercise and time with the family. It is happy with a secure section to patrol but can manage in a smaller home if walked properly. New Zealand's temperate climate suits the breed well, from cooler South Island winters to milder northern summers, though it should never be left outside as its only company. As a sensitive, people-focused dog, long stretches alone can lead to barking and boredom.

Nutrition and feeding

The Smooth Collie needs a balanced diet matched to its life stage and activity level, fed in measured meals to keep its weight in check.

The Smooth Collie does well on a complete, balanced dog food suited to its age, size, and activity level. A dog working stock or competing in sport burns more energy than a companion dog that potters around the section, so match portions to the individual rather than just following the bag. Keep an eye on body condition: you should feel the ribs without pressing hard and see a waist when looking down at the dog.

General feeding guide
Life stageAmount per dayMeals
Puppy (2 to 6 months)Per growth formula, weight-based3 to 4
Puppy (6 to 12 months)Per growth formula, weight-based2 to 3
AdultAbout 250 to 400 g of quality dry food, by weight and activity2
SeniorReduced calories, joint support as advised2

Treats and supplements

Keep treats to around 10 percent of daily calories and use them mostly for training rewards. Most Smooth Collies on a complete diet do not need supplements, though a vet may suggest joint support for older or very active dogs. Keep fresh water down at all times, and bring in any diet change gradually over several days.

Health and lifespan

The Smooth Collie is generally healthy with a typical lifespan of 12 to 14 years, though it shares several inherited conditions with the wider Collie breed, including eye and drug-sensitivity issues.

The Smooth Collie is a generally robust breed with a typical lifespan of 12 to 14 years. Like all Collies, it carries a handful of inherited health risks, and responsible breeders screen their breeding stock for the conditions known to turn up in the breed. Buying from health-tested parents cuts the odds of these problems significantly. Anyone bringing a Smooth Collie into New Zealand from overseas should also budget time for MPI's biosecurity requirements, which include import health standards and a period in an approved quarantine facility given the country's rabies-free status.

Common conditions
ConditionSignsNote
Collie eye anomalyOften none visible; detected on eye examInherited; puppies should have eyes checked early
Progressive retinal atrophyNight blindness, declining visionInherited; DNA tests available in many lines
MDR1 drug sensitivitySevere reactions to certain common drugsDNA test available; inform your vet of status
Hip dysplasiaStiffness, limping, reluctance to exerciseScreened by hip scoring in breeding dogs

Preventive care

  • Keep vaccinations and parasite control up to date.
  • Schedule annual veterinary checkups, more often for seniors.
  • Request an MDR1 (drug sensitivity) test result and share it with your vet.
  • Maintain dental care and a healthy weight.
  • Have eyes checked as advised, especially in puppies and breeding dogs.

Training

The Smooth Collie is highly intelligent and eager to please, making it one of the easier breeds to train when handled with a calm, reward-based approach.

The Smooth Collie sits among the more trainable dog breeds going round. It picks things up fast, watches its handler closely, and responds well to praise and rewards. It is a sensitive dog, so heavy-handed corrections backfire and can make it shut down or turn anxious. Calm, consistent, reward-based training gets the best results.

Start socialisation and basic training early. Because the breed is alert and can be quick to bark, teaching a solid quiet cue and managing barking from puppyhood pays off. The herding instinct can surface as chasing or trying to gather people or animals, and training with the right outlets helps redirect that energy.

Basics

  1. Start socialisation with people, dogs, and new places from puppyhood.
  2. Teach name recognition and a reliable recall first.
  3. Add the core cues: sit, down, stay, and leave it.
  4. Bring in a quiet cue early to manage barking.
  5. Build up duration and distraction gradually.
  6. Move on to a dog sport such as obedience, agility, or herding trials.

Breeding

Smooth Collies reach breeding maturity in their second year, carry litters for around nine weeks, and typically produce medium-sized litters that need careful early socialisation.

Responsible breeding of Smooth Collies starts with health-tested parents. Breeders screen for the conditions common in the breed, including eye anomalies and MDR1 drug sensitivity, and select for sound temperament and structure. Bitches should be fully grown before their first litter, and reputable breeders will not mate them on their first season.

Gestation runs roughly 63 days. The dam usually whelps without trouble, though a quiet, prepared whelping area and a vet on call are sensible precautions. Puppies arrive deaf and blind and rely entirely on the dam for the first few weeks.

Early socialisation matters for this sensitive, clever breed. From a few weeks old, puppies benefit from gentle handling and exposure to everyday household sounds and sights, which sets up the confident, people-focused temperament the breed is known for. Puppies usually head to their new homes at around eight weeks, and buyers should ask to see health test results for both parents before committing.

Frequently asked questions

Common questions about the Smooth Collie cover its size, temperament, care needs, lifespan, suitability for families, and how it compares with the Rough Collie.

How big does a Smooth Collie get?

It is a medium-sized dog, standing roughly 51 to 61 cm (20 to 24 in) at the shoulder and weighing about 18 to 30 kg (40 to 66 lb), with males running larger than females.

What is a Smooth Collie's temperament like?

Gentle, loyal, and clever. The breed is usually good with children and other pets, alert and a bit reserved around strangers, and strongly attached to its family.

Is a Smooth Collie easy to look after?

Grooming is simple thanks to the short coat, needing only a weekly brush and a bit more during the seasonal blow. The main commitments are a daily walk and regular company, since the breed does not cope well left alone.

How long do Smooth Collies live?

The typical lifespan is 12 to 14 years. Health screening of breeding stock and routine preventive care support a long, healthy life.

Is a Smooth Collie a good family dog?

Yes. It is known as a patient, affectionate family companion that generally gets on well with children, provided it gets daily exercise and is not left alone for long stretches.

What is the difference between a Smooth Collie and a Rough Collie?

They share the same build, temperament, and history, and differ mainly in coat. The Smooth Collie has a short, flat coat, while the Rough Collie has a long outer coat. Some registries treat them as varieties of one breed, others register them separately.

Are Smooth Collies vocal?

They can be. As an alert herding breed, the Smooth Collie often barks to flag visitors or activity, so teaching a quiet cue early makes a real difference.
