About the Cairn Terrier
The Cairn Terrier is a short-legged, strongly built little dog with a foxy expression, small pointed ears and a hard, shaggy coat. It is a game, rugged, workmanlike terrier: fearless, assertive and hardworking, but also cheerful and affectionate.

The Cairn is one of Scotland's native breeds. From the 17th century it was used in the Western Highlands and on the Isle of Skye to keep down vermin that threatened game, often working in small packs. Its name comes from the cairns, the piles of stones on the highland moors where its quarry hid. Despite being the smallest of the working Scottish terriers, it was also used to tackle foxes, otters and even badgers.
The Cairn shares ancestry with the Skye Terrier, the Scottish Terrier and the West Highland White, and was first exhibited as a short-haired Skye Terrier. Its appearance has changed remarkably little over the centuries.
Cairn Terrier temperament
Cairns are typically cheerful, alert, lively and extrovert. They bond closely with their owners and like to be part of everything they do. They do not usually tolerate being left alone for long.
Thanks to their history as pack terriers they generally get on well with other dogs, although some may have issues with dogs they do not know. Their strong hunting instinct means they need early socialisation with cats and other small pets, and they may not be safe with small furry animals or unfamiliar cats. They tend to be vocal and will bark to alert you to visitors.
Size and appearance
Cairns are small dogs. Adults typically stand 28–31 cm at the shoulder and weigh around 6–8 kg.
The weatherproof double coat has a hard, profuse outer layer and a short, soft undercoat. Colours include cream, wheaten, red, grey and nearly black, with brindling in all of them.
How much exercise does a Cairn Terrier need?
Cairns are bursting with energy and need at least an hour of exercise a day, ideally with lots of interesting smells to explore. They also need games, interactive toys and enrichment to occupy their minds, and many love a chance to dig.
Take care off the lead: once on a scent it can be hard to get their attention back. They can live happily in a flat or a city, but they enjoy a garden, ideally with a digging pit, and regular access to the countryside.
Training a Cairn Terrier
Cairns can be very independent and stubborn, so training needs patience and persistence. They are more biddable than many terriers, though, and with fun, reward-based training they can reach a surprisingly high level, even in sports such as mini-agility.
- Use fun, reward-based methods to keep them motivated.
- Be patient and persistent.
- Train a reliable recall, but keep them on the lead unless the area is secure.
- Socialise early with other animals, including cats and livestock.
Cairn Terrier grooming
Brush and comb the coat once or twice a week, and check it over after walks. The coat usually moults twice a year, and at these times it should be hand-stripped to remove the dead hair. The breed does shed.
Living with a Cairn Terrier
Once well socialised, Cairns usually get on very well with children and can make excellent, fun family pets. They may not have much patience with younger, unruly children who want to grab or chase them, so teach children to respect the dog. Whatever the breed, dogs and young children should never be left alone together, and an adult should supervise every interaction.

Cairn Terrier health
Not yet reviewed by a vet. This is general information, not veterinary advice: speak to your vet about your own dog’s health.
Purina describes the Cairn Terrier as a generally healthy breed, but some conditions are recognised. The Royal Kennel Club recommends eye testing under the BVA/KC/ISDS Eye Scheme as best practice. Ask about the health history of a puppy's parents and grandparents.
Patellar luxation
The kneecaps can slip temporarily out of place.
Glaucoma
Increased pressure within the eye.
Cataracts
Clouding of the lens of the eye, giving it a cloudy appearance.
Atopy
An allergic sensitivity to things in the environment, causing sore, itchy skin.
Portosystemic shunt
An abnormal blood circulation in which blood bypasses the liver, leading to a build-up of toxins.
Von Willebrand's disease
A blood clotting disorder that can result in excessive bleeding.
Legg-Calvé-Perthes disease
The blood supply to the head of the thigh bone is reduced, causing the bone to break down.
What health checks should you ask about?
Responsible breeders and rescues are happy to talk about health, and any pressure to decide quickly is a reason to walk away. Before taking a Cairn Terrier home, it is reasonable to ask about:
- Health testing of the parents. Ask which health tests the parents have had for conditions known in the breed, and to see the results.
- Veterinary and vaccination records. Puppies should have had a first vaccination and a vet check, with records you can take home.
- Microchip information. In England, Scotland and Wales puppies must be microchipped and registered by eight weeks old. Ask who the chip is registered to and how the transfer works.
- Registration paperwork. Registration papers, where they apply, record pedigree. They do not by themselves prove health or how a puppy was raised.
How much does a Cairn Terrier cost to own?
There are two costs: bringing a Cairn Terrier home, and looking after one well. Puppy prices depend on the breeder, health testing and demand; the adverts below show what sellers are asking today.
Ongoing costs are the ones new owners most often underestimate: food, insurance (which usually rises with age), routine vet care, vaccinations and parasite treatment, dental care, grooming, training, bedding and equipment, and boarding or a sitter for holidays. Budget for the whole of the dog’s life, typically from 10 years, not just the first year.
Buying a Cairn Terrier
If you have decided the Cairn Terrier suits your life, take the same care choosing where your dog comes from. Meet the puppy in person, see it with its mother, and look at how the litter is raised.
- Check who you are dealing with: every Mypetzilla advert shows the seller type and what we have checked.
- Ask about health testing, vaccinations and the microchip before you commit.
- Take your time. Do not be rushed by deposits or "last one left" stories.
- Meet in person before paying anything, and keep conversations on Mypetzilla.
Adopting a Cairn Terrier
Cairn Terriers do come up for adoption, through rescue organisations, breed rescues and private rehoming, often because an owner’s circumstances have changed rather than any fault of the dog. An adult dog arrives as a known quantity: its size, coat and character are already on show.
Rescues will usually talk you through the dog’s history, any medical care, and the home it needs, including children, other animals and time alone. Be honest about your circumstances: a good rescue would rather place a dog once, well.
