Scottish Terrier

The Scottish Terrier is one of the oldest terrier breeds in Scotland, with documented history stretching back centuries in the Highland region. The breed was developed as a working terrier for hunting vermin in rocky Highland terrain — badgers, foxes, and rats in burrows and dens that demanded a dog of small stature, extraordinary courage, and relentless drive. The rugged Highland environment where the breed worked shaped not just the physical type but the temperament — the fierce independence and tenacity that defines the Scottie today is a product of selection for dogs that would pursue dangerous quarry underground without hesitation.

The modern breed standard was established in the late 1800s, and the AKC recognized the Scottish Terrier in 1885, making it one of the earliest AKC-recognized breeds. The breed gained enormous popular recognition and cultural prominence in the 20th century.

Fala and the White House

Franklin D. Roosevelt's Scottish Terrier Fala is one of the most famous dogs in American presidential history. Fala was Roosevelt's constant companion, accompanied him to international meetings including the Atlantic Charter conference, and became a national figure in his own right. A bronze statue of Fala stands beside Roosevelt at the FDR Memorial in Washington, D.C. — one of the few presidential dogs to have been commemorated in a national monument.

Cultural Icons

The Scottish Terrier's distinctive silhouette — the upright ears, beard, and low-slung profile — became one of the most recognizable in dogdom. The Scottie appears as a Monopoly board game token (one of the original pieces), on Scotch Whisky bottles, and in countless advertisements and cultural references. Few breeds have achieved the level of visual recognition that the Scottie's distinctive profile commands.

The Scottish Terrier is independent, dignified, feisty, and deeply loyal to its chosen people. This is not an effusive breed — the Scottie does not perform social warmth for strangers or seek wide approval. Within its family, it is devoted and expressive in its own reserved way. Outside that inner circle, it is self-possessed and unimpressed.

The Diehard Character

The nickname "The Diehard" is one of the most accurate breed descriptors in dogdom. Scotties are relentlessly determined. When they want something, they pursue it. When they have decided they do not want something, no amount of coaxing will convince them otherwise. This quality made them superb underground hunters and makes them fascinating, occasionally exasperating companions.

Selective Affection

The Scottish Terrier forms strong bonds with its family but distributes its affection selectively. It is not a cold or unloving breed — but it is not an indiscriminate people-pleaser either. The Scottie chooses its people carefully and once chosen, is genuinely devoted. Strangers are assessed with dignified suspicion until proven acceptable.

With Children

The breed rates 2/5 for good with kids — reflecting the reality that Scotties have genuine tolerances and will not indefinitely absorb rough handling or disrespectful behavior from children. They do well with older children who understand dog body language. Very young children who are unpredictable around the dog create management challenges.

The Scottie's behavioral core was forged in the Scottish Highlands — a dog that had to be bold enough to enter burrows after dangerous quarry, stubborn enough to not give up, and independent enough to work without direction from the hunter above ground.

Prey Drive

Significant prey drive directed at small animals — squirrels, rabbits, and rodents trigger the chase response quickly. Off-leash reliability in open environments with prey animals present is variable. Leash discipline and secure fencing are management requirements.

Digging

Scotties dig. This is instinctual behavior from working underground, and it will not be trained away entirely. Garden management and awareness of fencing dig vulnerabilities are practical necessities.

Stubbornness

The most defining behavioral characteristic for owners is the independence — the Scottie's willingness to simply decide it is not going to do something and nothing you do will change that in the moment. This is not aggression, defiance, or stupidity. It is breed character. Understanding this and working with positive reinforcement and genuine engagement produces far better results than confrontation.

Puppy (0–6 months): Socialization Is Critical

Scottie puppies are bold, curious, and already showing the stubborn independence of the adult breed. Broad socialization with diverse people, children, other animals, and environments is essential — the Scottie's natural aloofness with strangers and limited patience with children needs positive early exposure to develop appropriate adult behavior. Begin positive reinforcement training immediately; establish routines and expectations early.

Adolescent (6–18 months)

The adolescent Scottie solidifies its independence and develops full prey drive. Stubbornness can peak. Maintain consistent training with patience and positive reinforcement. This stage tests owners who expect easy compliance; those who work through it produce well-adjusted adults.

Adult (2–8 years)

A well-socialized adult Scottish Terrier in a household that suits its temperament is a deeply satisfying companion. Annual urinalysis is recommended for bladder cancer monitoring, starting no later than middle age. The grooming commitment is ongoing.

Senior (8+ years)

Monitor closely for bladder cancer symptoms — difficulty urinating, blood in urine, recurrent apparent UTI — in senior Scotties. The bladder cancer risk increases with age. Twice-yearly veterinary visits are appropriate. Maintain exercise appropriate to the individual's condition.

The Scottish Terrier's health profile is defined by two concerns of very different characters: bladder cancer (transitional cell carcinoma), which is primarily an environmental and aging issue with no DNA test, and the DNA-testable conditions vWD and Scottie Cramp, which responsible breeders address through mandatory testing.

Bladder Cancer: The Serious Environmental Risk

Scottish Terriers are estimated to be 18 to 20 times more likely to develop transitional cell carcinoma (TCC) of the bladder than mixed-breed dogs. TCC is a malignant cancer that infiltrates the bladder wall, causing blood in urine, difficulty urinating, and symptoms that frequently mimic urinary tract infection. It is often misdiagnosed as UTI in early stages. The association with lawn herbicide and pesticide exposure — particularly phenoxy herbicides — is well-established. Do not use chemical treatments on any lawn surface that your Scottie accesses. Annual urinalysis is the most practical early detection tool.

von Willebrand Disease (vWD)

An inherited bleeding disorder — the DNA test is required for breeding dogs. Affected dogs can bleed excessively from minor wounds or during surgery. Clear-to-carrier breedings are acceptable; clear-to-clear is preferable for eliminating affected offspring.

Scottie Cramp

The breed-specific movement disorder triggered by excitement or exercise — the DNA test is now available and required for responsible breeding. Mildly affected dogs have acceptable quality of life but should not be used for breeding.

Grooming: The Signature Commitment

The Scottish Terrier's wiry double coat is one of the breed's most distinctive features and one of its most significant care requirements. The correct coat texture requires either hand-stripping (pulling the dead outer guard hairs by the roots to maintain texture and pattern) or professional clipping every 6 to 8 weeks. Hand-stripping is the correct method for show dogs; clipping is acceptable for companion dogs but progressively softens the coat. The beard, eyebrows, and leg furnishings require regular brushing to prevent matting. Professional grooming is not optional — it is a recurring ownership cost.

Exercise: Moderate But Consistent

The Scottish Terrier rates 3/5 for energy — not a high-drive breed, but not sedentary. Daily walks and playtime are necessary and sufficient for most individuals. The Scottie enjoys exploring, sniffing, and independent activity but does not require the sustained vigorous exercise of sporting or working breeds.

Lawn Chemical Policy

This is specific to the breed and not something most dog care guides address: given the documented association between phenoxy herbicide exposure and the breed's extremely high bladder cancer rate, the responsible standard for Scottie owners is no chemical herbicide or pesticide treatment on any lawn surface the dog regularly accesses. This means the owner's lawn, and managing access to treated neighbors' lawns as much as possible.

Training

Positive reinforcement only — the Scottie responds to interesting, rewarding training and simply shuts down when faced with correction or repetition. Patience, genuine engagement, and understanding that the Scottie is evaluating whether compliance is worthwhile produces better results than any other approach.

The Relationship Is Earned

Living with a Scottish Terrier means accepting a companion that does not give its loyalty and affection universally — it chooses its people and its relationships with genuine selectivity. For owners who value that selective loyalty, the bond with a Scottie is deeply satisfying. For those who expect the breed to be effusive and accommodating with everyone, the experience will be different from their expectations.

Household Compatibility

Scotties do well in a range of housing types when their exercise needs are met — including apartments and urban settings. They are not high-energy enough to require large outdoor spaces. They adapt well to the rhythms of their household once established in their routines.

With Other Pets

Dog-to-dog tolerance varies by individual and socialization. Scotties can coexist with other dogs they are raised with; unknown dogs may be assessed with suspicion. Small animals trigger prey drive and are not appropriate cohabitants. Same-sex aggression is possible.

The Annual Health Monitoring

Annual urinalysis is a practical ongoing commitment for Scottie owners — the early detection of bladder cancer through urinalysis can provide more treatment options. This is not optional monitoring; given the breed's exceptional TCC rate, it is a routine standard of care.

Responsible Scottish Terrier breeding requires vWD DNA testing and Scottie Cramp DNA testing on all breeding dogs. These are non-negotiable. The bladder cancer issue — while the most serious health concern in the breed — cannot be addressed through DNA testing and must instead be managed through environmental precautions and early detection protocols.

Pregnancy Overview

• Average litter size is 3–5 puppies — smaller than many terrier breeds
• Small litters mean individual puppy monitoring is straightforward but every puppy carries more weight
• Natural whelping is typical; be alert to dystocia risk given the breed's compact build
• Daily weight tracking from birth is essential even in small litters

Week-by-Week Pregnancy

Weeks 1–3: No visible changes. Maintain normal activity. Establish baseline weight for the dam. Some dams show brief nausea around days 21–28.

Weeks 4–5: Ultrasound confirmation from approximately day 25. Appetite increases. Transition to a higher-calorie pregnancy diet appropriate for small breeds. The dam may become more settled and rest-oriented.

Weeks 6–7: Abdominal enlargement becomes visible. Nesting behavior develops. Reduce vigorous exercise. Introduce and establish the whelping box.

Weeks 8–9: Radiograph at day 55 or later for puppy count — especially important in this breed to confirm the expected number given typical small litter sizes. Begin twice-daily rectal temperature monitoring. A drop below 99°F signals labor within approximately 24 hours. Confirm emergency veterinary contacts.

Whelping

Scottish Terrier dams typically whelp naturally but the compact body type means dystocia risk requires awareness. Weigh each puppy immediately after birth. Contact your veterinarian if the dam strains unproductively for more than 30 minutes or if more than 2 to 3 hours pass between puppies. See the Whelping Date Calculator for timeline planning and the Whelping Supplies Checklist for kit preparation.

Newborn Puppy Weight Tracking

Use the Animal Weight Tracker to log each puppy's weight from birth. Puppies should double their birth weight within 7 to 10 days. Any puppy failing to gain weight after day 2 needs supplemental feeding and veterinary assessment. See the fading puppy syndrome guide for warning signs and intervention steps.

Growth Expectations

The Scottish Terrier is one of the most distinctive and genuinely characterful breeds available — for owners who match well with the temperament. It is also a breed where the gap between owner expectation and breed reality can be significant.

The Cancer Risk Is Serious

Being 18 to 20 times more likely to develop bladder cancer than the average dog is not a minor statistical footnote. It means that a meaningful percentage of Scottish Terriers will develop TCC during their lifetimes. The association with lawn chemical exposure means the primary prevention strategy is environmental — not using phenoxy herbicides on lawns the dog accesses. The secondary strategy is annual urinalysis for early detection. Every Scottie owner should understand and accept this and implement both strategies.

The Independence Is the Breed

Owners who acquire a Scottish Terrier expecting a small, biddable companion will be surprised. The Scottie's independence, stubbornness, and dignified self-possession are not training problems — they are the breed. Training a Scottie requires patience, positive reinforcement, and the acceptance that compliance will be given on the dog's terms. This is not a breed for owners who need consistent, reliable obedience.

For the Right Owner

For experienced owners who appreciate the Scottie's unique character — its selective devotion, its fearless confidence, its dignified personality — this is an outstanding breed. The grooming commitment is real but produces one of the most distinctive-looking dogs in existence. The health challenges are manageable with appropriate awareness. The Diehard earns its name, and the right owner finds that quality not exasperating but deeply admirable.

AKC Popularity

The Scottish Terrier has declined from mid-century peak popularity to a current ranking in the 50s to 70s — still a well-recognized breed but no longer as common as it once was. The decline correlates with the general decline in popularity of many traditional terrier breeds as companion dog preferences have shifted toward more openly social breeds.

Bladder Cancer Research

The Scottish Terrier has been the subject of multiple published studies on canine transitional cell carcinoma due to its extreme susceptibility. Research at Purdue University and other institutions has established the phenoxy herbicide association and identified genetic susceptibility factors. The breed has contributed significantly to the understanding of canine bladder cancer, which has applications beyond the breed itself.

OFA Health Data

OFA data for Scottish Terriers reflects the primary testable conditions — vWD and Scottie Cramp DNA testing participation has grown as the tests have become available. Patella evaluation data shows rates typical for small terrier breeds. The bladder cancer prevalence in the breed is characterized primarily through oncology studies rather than OFA data, as TCC is a disease concern rather than an orthopedic or genetic screening issue.
