The Biewer Terrier gives you the impression of a small dog that knows it's lovely and carries itself accordingly. There's an elegance to the way they move that seems almost improbable for a seven-pound animal - light-footed, straight-backed, carrying that flowing coat like a train. Stand one next to a Yorkshire Terrier and the family resemblance is obvious, but the Biewer reads as slightly more refined, with the tricolor coat replacing the Yorkie's familiar blue and tan with something distinctly its own.
The head is moderately round, not overly domed, with a flat skull when viewed from above. The muzzle is of medium length and reasonably fine - this is a toy breed, not a snipey one, and the jaw should be strong enough to give the face a balanced look. The nose is black. Eyes are one of the breed's most expressive features: they are medium-sized, dark, and nearly round, set forward in the skull to give the dog a bright, direct expression. They shouldn't look bulging or protuberant - the Biewer's eye is set more naturally than some toy breeds. The bite is scissors.
The ears are small, V-shaped, and erect - this is a non-negotiable feature of the breed. They are set high on the skull and carried forward. Young puppies often go through an ear phase where one or both ears flop, and breeders sometimes assist by supporting the cartilage until the adult muscle develops, which is common in terrier breeds with prick ears. In a properly mature dog, both ears stand firmly and independently, giving the face its characteristic alert expression.
The neck is of moderate length and flows smoothly into well-laid shoulders. The topline is level, and the body is square - measuring from point of shoulder to point of buttock should approximate the height at the withers. The chest is neither barrel-shaped nor excessively narrow; it has good depth for a dog of this size. The loin is short and muscular.
The tail is set high, carried in an arch over the back, and completely covered in a profusion of long hair that gives it the pom-pom appearance that inspired the breed's early name. This tail carriage is a hallmark of the breed - a drooping or low-carried tail on a moving Biewer catches the eye immediately as incorrect.
The legs are straight and fine-boned. The feet are small, compact, and round with dark nails. The hindquarters are moderately angulated with well-muscled thighs and parallel rear legs when viewed from behind. Movement should be free and effortless, with good reach in front and drive from behind, the back remaining level under motion.
The coat is the Biewer's most stunning attribute. It is a single layer - there is no undercoat - of fine, silky, perfectly straight hair that parts down the center of the back from the back of the skull to the root of the tail. In show trim the coat reaches the floor, the head fall is typically gathered into a topknot, and the leg furnishings flow outward with each step. The texture is genuinely silky to the touch, not cottony or wavy. A dog with a coarse or curly coat is not correct. Because there is no undercoat, the Biewer sheds very little - loose hairs are caught in the outer coat and removed during brushing rather than falling freely around the house.
Tricolor distribution: the body is primarily blue or black and white with the two colors forming clearly defined sections rather than a blended or roan pattern. The head shows the gold or tan coloring prominently, typically on the face, above the eyes, and at the sides of the muzzle. There should be tan on the legs as well. The combination of these three distinct colors - the cool blue or deep black, the crisp white, and the warm gold or tan - is what makes a well-marked Biewer striking from across the room. Solid-colored, bicolor, or heavily blended specimens fall outside the standard.
Males and females are similar in overall appearance, with males occasionally showing slightly more substance. The size overlap between sexes is complete - both range from four to eight pounds, though a well-bred female at the lighter end and a well-bred male at the heavier end will look distinctly different in their physical presence.
Gait is a useful indicator of structural correctness in this breed. A properly built Biewer moves with a free, easy stride that covers ground without exaggeration - front feet reaching forward cleanly, rear feet driving from well-angulated hindquarters, the back remaining level and the tail arch maintained in motion. A choppy, hackney-action front suggests poor shoulder layback, while a crabbing rear suggests structural imbalance. At a trot the feet converge toward a center line as speed increases, which is correct for a dog of this size and proportion. What you don't want to see is any suggestion of rolling, paddling, or stiffness, which in a toy breed of this age can signal patellar or structural issues worth investigating.
Size is worth addressing practically: four to eight pounds covers real ground. A Biewer at the low end of that range is a genuinely tiny animal requiring careful management around larger dogs, young children, and household hazards like recliner chairs. A Biewer at eight pounds is noticeably more solid and durable while still being a toy breed. When choosing a puppy, discuss with the breeder what size the parents are and what the projected adult weight looks like for each puppy in the litter - surprises in either direction are worth anticipating.
Affectionate With Family
★★★★★
Biewers are velcro dogs through and through - they want to be with their people constantly and will follow you from room to room. This is not a dog who does well being left to its own devices for long stretches.
Good With Young Children
★★★☆☆
Biewers enjoy children but their small size makes them vulnerable to accidental injury from toddlers who squeeze or drop them. They do best with kids old enough to understand gentle handling.
Good With Other Dogs
★★★★☆
Unusually social for a terrier, Biewers generally get along well with other dogs and often enjoy canine companionship. They lack the typical terrier chip-on-the-shoulder attitude.
Shedding Level
★☆☆☆☆
The Biewer has hair rather than fur and sheds minimally - loose hairs tend to stay in the coat rather than landing on your furniture. Regular brushing pulls out what little shedding occurs.
Coat Grooming Frequency
★★★★☆
In full show coat the Biewer needs daily brushing to keep that long silky fall tangle-free. Most pet owners opt for a shorter trim that brings maintenance down to a few times a week.
Drooling Level
★☆☆☆☆
Biewers are a dry-mouthed breed with no tendency to drool or slobber.
Coat Type
★★★☆☆
The coat is a single layer of fine, silky hair that parts down the back and flows to the floor in show trim. No undercoat means less shedding but the long hair mats without regular attention.
Openness To Strangers
★★★★☆
More socially open than many terriers, Biewers typically greet strangers with curiosity rather than suspicion. They may bark an initial alert but warm up quickly.
Playfulness Level
★★★★★
Biewers maintain a puppy-like, whimsical quality well into adulthood - they love to play, tote toys around the house, and will invent games if you don't provide them.
Watchdog/Protective Nature
★★★☆☆
They'll alert bark at sounds and strangers, which is about the extent of their protective contribution. No one is going to be deterred by a seven-pound dog, but you'll know when the mail arrives.
Adaptability Level
★★★★★
Biewers adapt readily to apartment living, travel, and varied routines as long as they have their person with them. They're equally at home in a studio apartment or a farmhouse.
Trainability Level
★★★☆☆
Smart and generally willing to please, but they carry a thread of terrier stubbornness that surfaces when they decide something else is more interesting. Short, positive sessions work best.
