The dog pulled harder than my husky back home, and he was only a year old. We were housesitting a young American Staffordshire Terrier, sixty-odd pounds of muscle on the end of a lead. His owner had warned us in the handover notes that walks were hard work. She was right.
Two sits later we cared for an eleven-year-old female of the same breed. She walked beautifully. Same terrier, different training. Similar strength.
That gap explains the whole group. The American Kennel Club recognizes 32 breeds in its Terrier Group, yet most pet parents can name about four of the popular terrier breeds. Below we cover 15 different terrier breeds, several of which you have probably never met in a park.
For each of these terrier dog breeds you get origin, size, honest exercise numbers, grooming needs, health conditions and a straight answer on first-time ownership. Where we have lived with the breed, we say so.
What Terriers Were Originally Bred For
Farmers, gamekeepers and mill workers originally bred terriers to hunt vermin. The breed name comes from the Latin terra, meaning earth, because these dogs followed rats and foxes underground. An earth dog had to squeeze into a tunnel alone, then kill vermin with no human anywhere nearby.
That job description built the temperament. Terriers are tenacious, fearless and strong-willed because a cautious dog would have died in the burrow. As a result, terriers have a strong prey drive that traces directly to their hunting background.
The build follows the job as well. Terriers typically have sturdy bodies, deep chests and ears that either stand prick or fold neatly forward, all of which suited a dog working in tight underground spaces.
Beyond that, terriers are a diverse group of energetic and fearless dogs. Sizes range from the seven-pound Yorkie to the fifty-pound Airedale, and coats run from wiry to silky to smooth. Still, the bold and energetic nature underneath stays consistent across the group.
Everything below reflects our experience and published research. It is not veterinary advice, so take any health question to your own vet.
1. Airedale Terrier
The Airedale Terrier is the largest terrier breed, standing about 23 inches and weighing 40 to 65 pounds. Yorkshire hunters created it in the Aire Valley to work rats and otters, and the British Army later used Airedales as messenger dogs.
We have never housesat one. However, a friend owned an older Airedale, and the thing I remember is how little the dog did. He barely barked, and he spent most of the day lying down. That is not the Airedale of the breed pages, though it is what a mature, well-exercised one often looks like at home.
Expect 60 to 90 minutes of daily exercise, outdoor activities and stripping of that wiry coat every couple of months. Lifespan runs 11 to 14 years, and hip dysplasia is the first thing to raise with your vet. You may also see a “Grand Airedale Terrier” advertised, though no major kennel club recognizes it.
2. Bedlington Terrier
The Bedlington Terrier looks like a lamb and runs like a whippet. Northumberland miners bred it in the early 1800s to kill vermin in the pits, then raced the dogs for money afterwards.
At 17 to 23 pounds, this is a fairly small dog with a curly, low-shedding coat. Clipping every six to eight weeks is the real cost here.
Bedlingtons carry a documented risk of copper toxicosis, an inherited liver disorder historically tied to the COMMD1 gene, though current DNA testing also screens for newer identified markers like ATP7B.
3. Dandie Dinmont Terrier
The Dandie Dinmont is the only dog breed named after a fictional character, a farmer in Walter Scott’s 1815 novel Guy Mannering. Scottish Borders hunters worked these long-bodied dogs on badger and otter.
They stand 8 to 11 inches and weigh 18 to 24 pounds. Compared with most terrier breeds they are calmer, though the prey drive is fully intact. Grooming means stripping the topknot and coat a few times a year.
4. Sealyham Terrier
Captain John Edwardes created the Sealyham Terrier in Pembrokeshire, Wales, around the 1850s. He wanted a white dog he could see against a dark badger, and the result weighs about 23 pounds at just 10 inches tall.
Sealyhams are noticeably steadier than the Russell types. In practice, that makes them one of the few terriers we would suggest for a quiet household, on about 45 minutes of daily exercise.
That white coat, however, is not low maintenance. Plan on trimming every six to eight weeks plus regular grooming to prevent matting. Lifespan runs 12 to 14 years, and lens luxation is the eye condition to ask about.
5. Cesky Terrier
The Cesky Terrier is the national dog of the Czech Republic, and the first Czech breed the FCI recognized. FrantiΕ‘ek HorΓ‘k produced his first litter in 1949 by crossing Sealyham and Scottish Terriers. He wanted a dog that was bold underground yet easy in the house, and he largely succeeded.
Ceskys are among the calmest terrier dogs, weighing 13 to 23 pounds with a soft silky coat. Interestingly, the breed standard specifies clipping rather than hand-stripping, which makes regular grooming cheaper than it looks.
Lifespan is typically 12 to 15 years on about 45 minutes of daily exercise. Numbers stay low outside Europe, so expect a waiting list.
6. Glen of Imaal Terrier
The Glen of Imaal Terrier comes from a remote valley in County Wicklow, Ireland, where farmers used it on badgers. It is a strange shape, with a compact body standing only 12 to 14 inches yet weighing 32 to 40 pounds.
Crucially, Irish farmers bred Glens to work silently underground, so they bark far less than other terrier breeds. That matters with close neighbours.
They need 45 to 60 minutes of daily exercise, secure fencing and a light strip twice a year. Progressive retinal atrophy has a DNA test available. Lifespan is 10 to 15 years.
7. Irish Terrier
The Irish Terrier is known for its bold and courageous nature, and its breed club has called it the “daredevil” for over a century. A red wiry coat and 25 to 27 pounds give it the look of a small Airedale.
Irish Terriers form strong bonds with their families and usually do well with children. That said, many terriers of this type will not tolerate other dogs, and this breed is a clear example.
Give one 60 minutes of daily exercise, plus hand-stripping two or three times a year. Lifespan is a healthy 13 to 15 years, with cystinuria the main inherited condition to ask about.
8. Cairn Terrier
Cairn Terriers were bred to hunt vermin in the Scottish Highlands, bolting foxes from the rock piles, or cairns, that gave the breed name its meaning. Toto in The Wizard of Oz was a Cairn, which is as close as most people get to recognizing one.
At 13 to 14 pounds, this is a small dog with an outsized opinion of itself. The shaggy double coat sheds lightly and needs stripping a few times a year.
Cairns are a genuinely playful breed and handle children well when early socialization starts young. Expect 30 to 45 minutes of regular walks. Lifespan is 13 to 15 years, with patellar luxation the common vet finding.
9. Scottish Terrier
The Scottish Terrier is the aloof one. Aberdeen breeders standardized it in the 1800s, producing a 10-inch dog of 18 to 22 pounds that decides for itself how affectionate it feels.
Scotties suit owners who like independence in a dog. Consistent training beats repetition here, because a bored Scottie simply stops participating. Budget 45 minutes of daily exercise and stripping twice a year.
Health is the serious conversation, because Scottish Terriers carry an elevated risk of bladder cancer. Notably, a Purdue case-control study found dogs on herbicide-treated lawns had roughly three to seven times the odds of developing it. That showed association rather than proof of cause, yet it is worth raising with your vet. Lifespan is 11 to 13 years.
10. West Highland White Terrier
The West Highland White Terrier is the most popular terrier breed here, and the white coat has a good origin story. Scottish sportsmen reportedly favoured white dogs so they would not shoot their own terrier by mistake. Still, that specific tale rests on thinner evidence than the internet suggests.
Westies weigh 15 to 20 pounds and need 45 to 60 minutes of daily exercise, plus stripping of the harsh double coat.
A UK VetCompass study of 6,605 Westies found a median lifespan of 13.4 years. Osteoarthritis appeared in 10.6% of dogs and skin infection in 7.2%. Itchy skin is the breed’s defining problem, so ask your vet about atopic dermatitis early.
11. Smooth Fox Terrier
The Smooth Fox Terrier has the smooth coat and the Wire Fox Terrier has the wiry one. English fox hunts originally bred both to bolt foxes from their earths. At 15 to 18 pounds, it is all spring and no off-switch.
Do not assume a smooth coat means low maintenance. Those short stiff hairs weave into upholstery, so shedding is heavier than most people expect.
We spent five weeks with two fox-terrier types living alongside Apple, a very small Shih Tzu, and the pair ran the room. Whenever all three dogs were with us, the fox terriers hoovered up every scrap of attention going and left Apple on the outside of it. Notably, that pushiness is the same forward, never-back-off temperament that made the breed useful at a fox earth.
12. Parson Russell Terrier and the Jack Russell Confusion
Parson Russell Terriers and Jack Russell Terriers descend from the same Devon hunting stock, developed by Reverend John Russell in the 1800s. Kennel clubs now separate them. The Parson stands 13 to 14 inches on longer legs, while the shorter Russell Terrier sits at 10 to 12 inches.
We housesat a Jack Russell type for four weeks, and Jackie noticed the pattern before I did. He slept on our bed every night and tracked every scrap of food in the house. Meanwhile, every walk turned into furious barking at every dog we passed.
Birds were the real target. One afternoon we found him in the garden with a dead bird we could not identify, still biting it long after it had stopped moving. It had probably been injured already, though we never saw the chase itself. Because we were in Australia, our bigger worry was what else he might corner, since cane toads are toxic to dogs and carpet pythons turn up in suburban gardens.
13. Yorkshire Terrier
The Yorkshire Terrier is a working ratter in a seven-pound package. Mill and mine workers bred them in the 1800s to kill vermin in cramped spaces, which is a long way from the handbag reputation.
I housesat a Yorkie in Sweden years ago, minding the dog for my Chilean friend while studying there. Two things surprised me. The dog was an unapologetic lap dog, climbing up the moment anyone sat down, and he proved relatively easy to train.
Then his friend arrived with a Pomeranian. The Yorkie accepted him the same day, yet it took several more days before the two of them actually played together.
That matters, because survey data ranks Yorkies high for stranger-directed reactivity. Individual dogs vary enormously.
14. Bull Terrier
Bull Terriers were never guard dogs. James Hinks refined the breed in 1860s Birmingham by crossing bull-and-terrier stock with the White English Terrier, producing a fighting dog he then marketed as a gentleman’s companion.
I expected an aggressive animal, mostly because of the menacing Bull Terrier in Babe: Pig in the City, the 1998 sequel rather than the original film. Instead, my tattoo artist’s Bull Terrier spent two sessions being relentlessly sweet and cuddly. The only reason I did not pet him more was the needle in his arm.
The evidence supports that second impression: a landmark 2008 canine behavior study by Dr. Deborah Duffy and Dr. James Serpell found bull-type breeds scored lower on stranger-directed aggression than their reputation predicts.
Expect 50 to 70 pounds, 60 minutes of daily exercise, a short easy-care coat and a 10 to 12 year lifespan. Deafness affects roughly 20% of pure white Bull Terriers, so ask about hearing tests.
15. American Staffordshire Terrier
The American Staffordshire Terrier taught us how much handler strength matters. Both dogs we sat came from the bull-and-terrier lineage the AKC recognized in 1936, and both carried 40 to 70 pounds of solid muscle.
The one-year-old male was anxious and relentless. His owner, a young woman, could not impose enough discipline to make walks pleasant, and honestly, neither could we.
By contrast, Cara, the eleven-year-old female we sat in Australia, had years of consistent training behind her and generally obeyed. Yet after a 40-minute walk she still had energy to burn. Both dogs would play with toys indefinitely, and both dug the garden every chance they got.
These are high energy dogs needing 60 to 90 minutes of daily exercise plus mental stimulation. Grooming is minimal. Lifespan is 12 to 16 years, and hip dysplasia plus the DNA test for cerebellar ataxia are the vet conversations.
Living With a Terrier: Exercise, Training and Grooming
Many terriers have high energy levels and require regular physical activity, which in practice means terriers need daily exercise of one to two hours. Long walks help, though the walk alone rarely settles them.
Terriers also benefit from mental stimulation like puzzle toys, scent games and short training drills. Those absorb the problem-solving drive a working terrier once spent underground. Deny it and the dog will invent a job you did not ask for.
Training a Terrier
Consistent and reward-based training is effective for terriers, while drilling the same command is not. Because these dogs were selected to decide things alone, they switch off the moment a session gets repetitive. Keep it short, pay well and stop early.
As some of you may know, I owned a Miniature Schnauzer for seven years as a teenager, and that dog remains my benchmark for the group. He barked at anyone outside the family, understood a large vocabulary, and would look where I pointed rather than at the finger itself. I assumed that was rare.
In fact, reading human pointing gestures is something dogs do better than chimpanzees or hand-reared wolves, which is one of the most replicated findings in canine cognition. The Schnauzer was not unusual for a dog. He was simply a good example of one.
Early socialization is crucial for well-behaved terriers, particularly around other dogs and small animals. Start it young, because the window closes fast.
Digging, Fencing and Other Pets
Terriers are prone to digging and need secure fencing. Both American Staffordshire Terriers we sat went at the garden constantly, and a real part of each day went on spotting the digging early and calling them off. Many terriers are expert diggers and escape artists, so walk the fence line before your dog does.
Terriers may not tolerate other pets, because the hunting instincts that made them useful are still switched on. A breed selected to kill small animals will chase your rabbit, and no amount of proper care fully removes that.
Frequently Asked Questions
Terriers were originally bred to hunt vermin and go to ground after burrowing animals. British and Irish working people developed most terrier breeds in the 1700s and 1800s to control rats, foxes and badgers. The name comes from terra, meaning earth.
Terriers are intelligent problem-solvers, though they score moderately on obedience rankings because they were bred to work independently. Terriers respond best to short, reward-based sessions rather than long drills.
Yes, the Miniature Schnauzer sits in the AKC Terrier Group, even though it is a German farm breed rather than a British earth dog. Germans developed it from the Standard Schnauzer to kill vermin around barns, which is the same job description. It also ranks 12th in Stanley Coren’s obedience-based intelligence list, higher than any British terrier.
Terriers Are a Spirited Argument for Doing Your Homework
The two American Staffordshire Terriers we sat shared a breed, a size and a lineage, yet walking them felt like two different jobs. Genetics gave us the engine. Training and age decided who was driving.
That is the honest takeaway from every terrier we have met. Research backs it up, because a 2022 study in Science found breed explains only about 9% of the behavioural variation between individual dogs. Ultimately, choose the breed for its needs, then do the work.
