They say you should never judge a book by its cover, and this is undeniably true for the Cairn Terrier. These adorable little pups have a rough-and-tumble appearance, but their small size often gets them mistaken for a lapdog. While they may climb into your lap for an occasional cuddle, Cairn Terriers are not content to be idle. This energetic breed thrives on activity and is happiest when they can be active with you. (The last time one was content to merely be watched was when they were on the silver screen.) And we’re not talking walks around the block, either. This diminutive dog will enjoy exploring the big, wide world as your hiking buddy. Cairn Terriers thrive on adventure, and if they could crank it up to 11, they would. So, make sure your hiking boots are ready to go, because it’s time for today’s exciting adventure.

Best For
The Cairn Terrier is best for active families (children included) that are dedicated to consistent training. Because of their small size, they are well-suited for apartment life.
Cairn Terrier Temperament
There is a whole lot of personality packed into the compact Cairn Terrier. They are a friendly, sociable breed who loves making new friends wherever they go, of both the two- and four-legged variety. So, yes, you can expect to leave any trip to the dog park with a puppy playdate booked for next week. Hope you like a full social calendar! Cairns are good with kids, and their scrappy personalities allow them to enjoy the rough-and-tumble play of an afternoon outside with the little kiddos (as long as they follow the no ear or tail pulling rule). Cairn Terriers generally do not have aggressive tendencies or are known to be biters, so social interactions should be happy ones.
Cairns were originally bred to hunt vermin out of rockpiles, or “cairns” in Scotland, so they are a working terrier breed. Rock piles are scarce nowadays outside of Scotland, but their high prey drive will keep them on alert for squirrels, bunnies or any other small furry animals that dare to invade their territory. Their instinct to dig is strong, so some savvy pet parents have been known to provide their Cairn Terrier with a sand box of hidden toys to dig for—this keeps their dog happy and their daisies intact. Win, win.
For the most part, their temperament is happy-go-lucky, and they’re never more content than when sharing an adventure with you. Energetic and curious, they’re always up for a game of fetch, a tussle with their favorite tug toy, or just a walk around the neighborhood. But beware the bored Cairn pup who will quickly turn into a barking Cairn pup—one who may not stop until the entertainment resumes making you—yup, you guessed it—your neighbor’s new favorite person. And while they are not known to be lapdogs glad to just watch the world go by, Cairn Terriers may well snuggle up at the end of a busy day for a chance to recharge before tomorrow’s adventure begins.

Cairn Terrier Health
Cairn Terriers lifespan tends to be long, about 14 to 15 years or more, and they are generally a healthy, hardy breed. But they have a few health problems you need to be aware of, so you can help your pup live the longest life possible.
- Luxating Patella: This is a condition in which the kneecap moves out of position. Depending on the severity, it can sometimes be treated with a brace. If not, surgery may be required.
- Diabetes: This metabolism disorder is not one that can be cured. However, your vet will work with you to manage it by determining the correct insulin dosage to keep your pet’s blood sugar level stable.
- Hypothyroidism: This condition, when the thyroid gland is underactive and metabolism therefore slows down, can affect nearly every bodily organ. Once diagnosed, it can be treated with a daily oral medication.
- Globoid Cell Leukodystrophy (GCL): Also known as Krabbe disease, this genetic disorder, which damages neurological function, is sadly always fatal. Physical therapy, medication, bone marrow or cord blood transplants can help minimize symptoms and discomfort, but there is no cure. The best way to prevent the disease is to be sure your breeder screens their dogs for this in advance of breeding.
- Portosystemic Vascular Anomaly (PSVA) and Microvascular Dysplasia (MVD): These related genetic disorders cause liver circulation not to function properly. Treatment may include medication or surgery, particularly for PSVA.
- Kidney Aplasia/Dysplasia: The abnormal development of one or both kidneys is a hereditary condition. Depending on the severity, treatment may include medication, fluid therapy, kidney support supplements, special diets and more. Regular monitoring of the condition may also be called for. Screening for this disorder before breeding is the only way to prevent it.
Cairn Terrier History
The origin of the Cairn Terrier lies in Scotland and the breed dates to the olden days. Not, not the ’80s (although it’s reasonable you’d think so. Their hair does look a bit like a classic ’80s Jon Bon Jovi coif). But this is the real olden days—the 17th century. They lived predominantly in the Western Highlands, in particular on the Isle of Skye, where they patrolled game preserves and farms.
For many years, they were lumped together with other terriers and collectively called “Scotch Terriers.” It wasn’t until the late 1800s that they were recognized as their own distinct breed. In those days, large mounds of rocks, or “cairns,” were used to mark a boundary or grave. Rodents and other vermin would take up residence inside and underneath the cairns and it was the Cairn Terrier’s job to dig and evict the critters. They were, in effect, the original Terminator. Arnold, eat your heart out. This was usually a one-dog job, but sometimes multiple dogs would work together as a pack and go after bigger critters such as foxes and otters.
The Cairn’s bravery, tenacity and independence were qualities that served them well when they were working the windswept Highlands of Scotland. The American Kennel Club (AKC) recognized the Cairn Terrier in 1913 as the 69th breed. In 1939, the whole world met the adorable breed when a Cairn Terrier was picked to play Toto in a little movie called “The Wizard of Oz.”
