Ultimate Yorkshire Terrier Guide: Traits, Care, Training & Health Tips

Quick take: The Yorkshire Terrier is a four-to-seven-pound terrier with a silky, hair-like coat that never stops growing, a bold personality that has no idea how small it is, and three health issues — dental disease, a collapsing windpipe, and slipping kneecaps — that shape almost every care decision you will make.

1. Introduction to the Breed

Most people meet the Yorkshire Terrier as a lapdog in a tote bag. That is a fair description of where the breed ended up, but it badly undersells where it came from. The Yorkie was built in the mills of northern England to kill rats in tight, filthy places, and the dog in your living room still carries that job description: alert, opinionated, and genuinely fearless in a body that weighs less than a house cat.

That gap between size and self-image is the whole breed. It makes Yorkies wonderful company — affectionate, funny, portable, deeply attached to their people — and it also makes them easy to get wrong.

What follows is the honest version: a coat that grows like human hair, a windpipe that needs a harness instead of a collar, teeth that need brushing, and a mind that needs a job. If you are deciding whether to buy a puppy or adopt an adult, read the health section twice.

2. History of the Breed

The Yorkshire Terrier is an Industrial Revolution dog. In the mid-1800s, Scottish weavers moved south into Yorkshire and Lancashire looking for work in the woollen mills, and they brought their terriers with them — small, hard-coated ratting dogs including the Clydesdale and the Paisley, both refined offshoots of the Skye Terrier that carried the blue-and-tan colouring the breed still wears today. Crossed with local English terriers such as the Waterside and the Old English Terrier, the result was a compact, long-coated dog that could go anywhere a rat could go.

These were working-class dogs doing working-class jobs: clearing vermin from mills, mines, and cellars, and earning side money in the rat pits. They were first shown under the unlovely name "Broken Haired Scotch Terrier," but by the 1870s they were so identified with one county that the name stuck — Yorkshire Terrier.

One dog did more than any other to fix the type. Huddersfield Ben, born in 1865, was a formidable show winner and ratter who weighed around eleven pounds but consistently sired smaller offspring. He is considered the father of the modern breed, and his blood runs through essentially every Yorkie alive. He was killed by a horse-drawn carriage at six, but by then the pattern was set: smaller, silkier, and increasingly a companion. Victorian ladies took to the breed, the American Kennel Club recognised it in 1885, and the Yorkie completed its journey from mill floor to parlour cushion.

The breed's finest hour came in a war. In February 1944, an American soldier found a four-pound Yorkie in an abandoned foxhole in the New Guinea jungle; Corporal William Wynne of Cleveland bought her for about six dollars and named her Smoky. She flew twelve combat missions, survived 150 air raids, and famously dragged a telegraph wire through a debris-choked seventy-foot culvert pipe under an airstrip — a job that would otherwise have exposed roughly 250 ground crew to bombing. She is also widely credited as the first documented therapy dog, visiting wounded servicemen starting in July 1944. She lived to fourteen, and there is a bronze memorial to her in Cleveland.

3. Physical Characteristics

Typical Size and Weight

The breed standard is blunt: a Yorkshire Terrier should not exceed seven pounds. Most adults stand seven to eight inches at the shoulder and weigh four to seven pounds, and a well-built Yorkie is compact and square rather than fragile-looking. Anything sold to you as a "teacup," "micro," or "pocket" Yorkie is not a separate variety — it is a Yorkie bred deliberately under standard, and dogs at two and three pounds carry markedly higher risks of hypoglycemia, fragile bones, dental crowding, and anesthetic complications. The price premium buys you a more delicate dog, not a rarer one.

Coat and Color

The coat behaves like human hair rather than dog fur: fine, glossy, perfectly straight, and continuously growing. Left uncut it reaches the floor and parts down the spine — the look you see in the show ring. Adult colouring is dark steel blue over the body with rich golden tan on the head, chest, and legs, but puppies are born black and tan and the blue can take one to three years to come in. The coat sheds very little, which is why Yorkies are often recommended to allergy-prone households; that is relatively true, but no dog is genuinely hypoallergenic.

Distinctive Features

Small, flat skull; a neat muzzle; medium-dark, sparkling eyes; and small V-shaped ears carried erect. The tail is carried slightly higher than the back. The overall impression should be a confident, upright little dog with an air of self-importance — the standard actually asks for it.

4. Personality Traits

Yorkies are affectionate, bossy, curious, and busy. They bond intensely with one or two people and would happily spend the entire day within three feet of them. They are also true terriers: quick to react, quick to bark, quick to chase a squirrel across a road if nothing is attached to them, and entirely unbothered by the size of the dog they are barking at.

Barking is the trait most owners underestimate. A Yorkie's default response to a noise in the hallway is to announce it, and in an apartment building that habit compounds fast if it goes unaddressed in the first year. The fix is not scolding — reward quiet, interrupt the pattern early, and give the dog enough mental work that the hallway stops being the most interesting thing in its day.

With socialisation they do well with respectful older children, cats they were raised with, and other dogs. What they do not tolerate is being grabbed or handled roughly, which is why most breeders and rescues steer them away from homes with toddlers — and why supervision at the dog park is part of the job.

5. Care Requirements

Exercise Needs

Two short walks a day — roughly fifteen minutes each — plus some indoor play is enough for a healthy adult. What matters more than distance is that the walks actually happen: a Yorkie who never leaves the apartment gets reactive and noisy, and a Yorkie who is carried everywhere never builds the muscle that protects those small knees.

One rule is non-negotiable: walk a Yorkie on a harness, never on a collar. The breed is prone to tracheal collapse, and every hard pull against a neck collar loads the exact cartilage rings that fail. Keep a collar on for ID tags — that is what collars are for on this breed — and attach the leash to a harness that spreads pressure across the chest.

And because a Yorkie carries almost no body fat under that coat, cold weather is a genuine welfare issue rather than a fashion excuse — our winter safety guide covers realistic temperature limits for small dogs.

Mental Stimulation

This is a ratting dog with nothing to rat. Give a Yorkie ten minutes of real problem-solving a day — a snuffle hunt for kibble, a puzzle feeder, a toy hidden under a blanket — and most of the nuisance barking and pacing that owners blame on the breed goes away. Brain games do more for a small terrier than an extra mile of walking ever will.

Grooming Needs

Because the coat is hair, it mats instead of shedding out. A full-length show coat needs daily combing; most pet Yorkies live in a short "puppy cut," trimmed to an inch or so all over, which drops maintenance to a thorough comb-out once or twice a week. Either way you are booking a professional groom every six to eight weeks, bathing no more than about every two weeks so the coat keeps its natural oils, and checking the ears and the hair around the eyes — Yorkies are prone to tear staining, and hair falling into the eye causes real irritation.

The tool that matters most is a comb, not a brush. A brush skims the top of a silky coat and leaves the mats forming underneath it, against the skin, behind the ears and in the armpits where they hurt. A comb has to reach the skin to pass through, which makes it the honest test of whether the coat is actually clean.

If mats have already formed, cutting them out is the last resort, not the first — our guide to removing mats without cutting walks through the technique, and choosing the right comb for the coat type saves you from buying the wrong tool twice. Prefer to browse? Here is the full grooming lineup.

Dietary Considerations

Feed a complete small-breed food that meets AAFCO standards, in a kibble size a tiny mouth can manage. Adults do best on two to three meals a day; puppies need three to four, because they are genuinely at risk of hypoglycemia if they go too long without eating. Keep treats under about ten percent of daily calories — on a five-pound dog a single chew can be a real share of the day's intake, and extra weight makes every one of this breed's joint and airway problems worse.

6. Health and Lifespan

Yorkies are long-lived — eleven to fifteen years is normal, and plenty reach sixteen — but they are not low-maintenance medically. Five conditions account for most of what you will actually see at the vet.

Dental disease

This is the number one health problem in the breed, not a footnote. Toy jaws hold full-size teeth in a small arch, which traps plaque, and Yorkies frequently retain baby teeth that crowd the adults. Untreated periodontal disease costs teeth and pushes bacteria into the bloodstream. Brush daily, start the habit in puppyhood so it is boring rather than frightening, and treat professional cleanings as a normal recurring cost of the breed.

Tracheal collapse

The C-shaped cartilage rings that hold the windpipe open weaken and flatten, producing the classic dry, honking cough that gets worse with excitement, pressure on the neck, or heat. It is progressive and it is common in toy breeds. You cannot cure it, but you can meaningfully delay and reduce it: keep the dog lean, use a harness rather than a collar for walking, avoid smoke and heavy household aerosols, and get any persistent cough looked at rather than waiting.

Patellar luxation

The kneecap slips out of its groove — you will see a skip-step, a brief three-legged hop, then normal walking again. Mild cases are managed with weight control and muscle condition; severe ones need surgery, and long-term luxation drives arthritis. Discouraging repeated jumps off furniture, and keeping a Yorkie at a correct weight, is real preventive care.

Portosystemic (liver) shunt

Yorkies have one of the highest rates of congenital liver shunt of any breed. A vessel routes blood around the liver instead of through it, so toxins are never filtered. Signs are a puppy who grows poorly, seems dull or disoriented — especially after meals — and in bad cases circles or seizures. It is diagnosable with bloodwork and imaging and often correctable with surgery, which is exactly why a slow-growing, "quiet" Yorkie puppy deserves investigation rather than reassurance.

Hypoglycemia

Small puppies have almost no glucose reserve. Weakness, wobbling, glazed eyes, tremors, or a puppy who suddenly will not eat is an emergency, not a phase. Frequent small meals prevent most episodes; ask your vet what to keep on hand for the ones you cannot.

Add Legg-Calvé-Perthes disease of the hip and a general anesthetic sensitivity that comes with being tiny, and the pattern is clear: with this breed, prevention is cheap and reaction is expensive.

7. Training and Socialization

Yorkies are bright and willful, which is a different thing from stubborn: they learn fast and then negotiate. They are also often less food-motivated than a Labrador, so find what your dog will actually work for — a squeaky toy, praise, a scrap of chicken — and pay well. Sessions of three to five minutes, several times a day, beat one long session every time.

House-training is the honest sticking point. Tiny bladders, a real dislike of cold wet grass, and owners who quietly tolerate accidents because the mess is small add up to the breed's reputation for being hard to house-train. It is not that Yorkies cannot learn — it is that the standard never gets enforced. Take the dog out on a schedule, go with them, reward outdoors, and clean accidents with an enzymatic cleaner so the spot does not become a habit.

Socialisation should be deliberate and gentle. Let a Yorkie puppy meet stairs, elevators, umbrellas, and calm adult dogs while everything is still novel rather than frightening — and resist scooping the dog up every time something happens, because being lifted repeatedly teaches a small dog that the world is dangerous. A five-foot narrow lead gives you control without adding weight to the walk.

Yorkies still need an ID collar even when they walk on a harness — a flat, lightweight band worn loosely, carrying tags and nothing else. We covered how to pick one in choosing durable collars for small breeds.

8. Ideal Home Environment

The Yorkie is one of the genuinely good apartment dogs — small enough to exercise indoors on a bad-weather day, sheds very little, and content to spend the evening on the sofa next to you. The catch is noise. In shared walls, an untrained alert-barker becomes a neighbour problem quickly, so treat quiet as a trained behaviour from week one rather than something you hope for.

They suit retirees, singles, couples, and families with school-age children who have been taught how to handle a small dog. They are a poor match for a household with toddlers, or for a home where nobody is around for ten hours a day. Yorkies are indoor dogs: too small for most cold, too fragile for loose dogs and birds of prey, and too attached to their people to be left in a yard.

Small practical details matter here in a way they do not with a big dog. Baby-gate the stairs while a puppy's joints are developing, add steps at the sofa, and watch the doors — a four-pound dog underfoot is easy to injure.

9. Best Beds and Toys for a Yorkshire Terrier

Yorkies are burrowers and curlers. They sleep pressed against something, and they lose heat on a hard floor faster than almost any other breed because there is so little of them. A bolstered bed scaled to a toy breed gives them a wall to lean on and traps body heat; an oversized bed does neither, and most "small" beds on the market are still built for a twenty-pound dog.

Senior Yorkies with arthritic knees benefit from more support than a thin pad can give — the reasoning is laid out in our guide to American-made orthopedic dog beds, and the full bed and pad collection covers crate pads for travelling dogs too.

On toys, the rule for a Yorkie is light and small. A toy this dog cannot pick up is not a toy; a heavy firehose tug is a jaw and neck strain, not a game. Look for soft plush the dog can carry, shake, and "kill" — the ratting instinct is still in there, and satisfying it is genuinely calming.

Cheap imported plush is a genuine hazard at this size, because a toy breed swallows what a Labrador only shreds — see five materials in imported dog toys you must avoid. For rotation ideas, enrichment toys that prevent destructive behaviour works on a five-pound terrier as well as on a shepherd, and the full American-made toy collection is worth a browse.

10. Adoption and Breeder Tips

A responsible Yorkie breeder will not be selling you a "teacup." They will breed to the standard, raise puppies underfoot in the house, and hold them until at least ten to twelve weeks — toy puppies leave later than large breeds because of the hypoglycemia risk. Ask specifically about patellar evaluations on the parents, whether any liver shunts have appeared in the line, and what the bite and retained-baby-teeth history looks like. A breeder who welcomes those questions is the one you want; a breeder who answers by talking about coat colour or "rare" sizes is not.

Adoption is a strong option with this breed. Yorkies land in rescue for reasons that have nothing to do with the dog — an owner moves into assisted living, or a family underestimated the grooming bill — and breed rescues are frank about barking, house-training status, and dental history because the dog has been in foster care. An adult with a known temperament beats a puppy lottery, and the dental work is often already done.

Whichever route you take, budget honestly first: professional grooming every six to eight weeks, dental cleanings, and insurance taken out before any of the breed's known conditions show up. Our pet care checklist covers the rest of the setup.
