Dog breed
Cairn Terrier
The Cairn Terrier is a small, wire-coated terrier from the Scottish Highlands, developed to flush foxes and rodents out of piles of stones called cairns. It's cheerful, brave and tough, with a natural, slightly scruffy look. The most famous Cairn of all was Toto from "The Wizard of Oz."

Temperament
The FCI standard describes the Cairn as active, game and hardy, fearless and cheerful, confident but not aggressive. It's a big personality in a small body: curious about everything, eager to play and keen to dig holes in the yard. The AKC rates it highly for affection, playfulness and alertness, and fairly high for barking as well. A Cairn likes people, but it's no lapdog to be carried around; it would rather be doing something. Its terrier instinct means rodents, birds and often the neighbors' cats bring out the hunter in it. It can be independent and stubborn, so it needs patient, consistent training with plenty of rewards. It usually gets along with other dogs, though it won't back down from a bigger one if it feels challenged.

Who is the Cairn Terrier for?
The Cairn Terrier suits people who want a small but tough dog with personality, for walks in the woods and mountains as well as for city apartment life. It does well in a family with older children. It's not a good choice for homes with hamsters or rabbits, for people who want a quiet dog, or for owners of a perfectly manicured yard, because a Cairn loves to dig.

Care and exercise
The Royal Kennel Club recommends up to an hour of exercise a day. A Cairn loves walks where it can sniff and dig, as well as search games and short training sessions. Let it off leash only in safe places, because the scent of a rodent can take over its attention completely. The harsh, wiry coat with a soft undercoat needs brushing several times a week and gentle hand-stripping of dead hair about twice a year. Don't clip a Cairn, because the coat loses its water resistance. Trim the nails regularly. The dog gains weight easily, so watch portions. Training should be short and varied, with patient recall practice from puppyhood. Dig-proof the yard, because a Cairn will enthusiastically dig under the fence.

The AKC considers Cairns generally healthy dogs, and breeders work together to keep it that way. Still, the AKC's list of recommended tests is fairly long: a patella evaluation, a cardiac exam, a kidney ultrasound for missing or underdeveloped kidneys, an eye exam for melanosis, a DNA test for globoid cell leukodystrophy, and liver tests for portosystemic shunt and microvascular dysplasia. The Royal Kennel Club recommends an eye exam as good practice. Melanosis can lead to glaucoma, so it's worth having the eyes checked periodically in a pet dog too. The AKC gives a life expectancy of 13–15 years.
- patellar luxationCommon in small breeds; the AKC recommends a patella evaluation for breeding dogs.
- portosystemic shunt and microvascular dysplasia of the liverDefects of the liver's blood vessels that the AKC recommends testing for.
- ocular melanosis (OM)Pigment buildup in the eye that can lead to glaucoma; detected by eye exam.
- globoid cell leukodystrophy (Krabbe disease)A severe neurological disease of puppies; a DNA test identifies carriers.
- kidney defects (aplasia or dysplasia)The AKC recommends a kidney ultrasound for breeding dogs.

Breed history
The Cairn is one of several Scottish terriers that kept farms and hunting grounds free of vermin for centuries. For a long time they were all simply called Scotch terriers, and only in the late 19th century were they separated into distinct breeds: the Cairn, Scottish, Skye and West Highland White. Dogs of this type were known from at least the 17th century in the western Highlands, especially on the Isle of Skye. The name comes from the piles of stones marking boundaries or graves, where foxes and rodents hid. The AKC recognized the breed in 1913. Its popularity took off thanks to the 1939 film in which Toto was played by a female named Terry.

Frequently asked questions
Do Cairn Terriers shed?
Not much; the AKC gives the breed a low shedding rating. But dead hair stays in the coat, so the dog needs regular brushing and hand-stripping about twice a year.
Are Cairn Terriers good with kids?
They do best with older children who understand that a dog isn't a toy. Cairns are sturdy and love to play, but they don't like being carried around and squeezed.
How long do Cairn Terriers live?
The AKC gives 13–15 years. It's one of the long-lived breeds, and a healthy weight plus regular eye and liver checks help keep the dog in shape.
Do Cairn Terriers bark a lot?
Quite a bit; the AKC gives the breed a high score for barking. A Cairn readily warns of visitors and reacts to animals outside the window, so start teaching it to settle early on.
How much does a Cairn Terrier weigh?
Adult dogs of this breed usually weigh: males 6–7.5 kg, females 6–7.5 kg. Height at the withers: 28–31 cm. That range is for healthy adults in good condition.
