Appearance

Primary Colors
Secondary Colors
Skin Type Domestic dog skin with a dense, long single coat; skin commonly shows darker pigmentation under the white coat (especially around nose/eyes). Not hairless; requires regular grooming to keep skin and coat healthy.
Distinctive Features
  • Small Italian companion breed (toy-sized) within Canis lupus familiaris; selectively bred for household companionship rather than hunting, herding, or guarding roles typical of many domestic dogs derived from the base species.
  • Coat: long, soft, fluffy/cottony texture; falls in loose flocks rather than a tightly curled, heavily sculpted show clip (distinct from the more curly, stylized look often associated with some other bichon-type breeds).
  • Color: characteristically solid white; coat can visually "puff" and look cloud-like when well brushed.
  • Head/face: rounded expression with dark, round eyes and a black nose; drop ears covered in long hair.
  • Body: compact, fine-boned, light build; carried as a true lap/companion dog rather than an endurance working type.
  • Temperament context: typically affectionate, people-oriented, and suited to indoor living; tends to bond closely and may be prone to separation-related stress without gradual training.
  • Care requirement: high grooming needs-frequent brushing/combing to prevent matting in the long cottony coat; regular face/eye-area cleaning to reduce tear staining on white hair.
  • Care requirement: routine ear checks/cleaning because drop ears and hair can reduce airflow; regular dental care is important due to small-breed predisposition to tartar.
  • Health concerns (breed-typical risk areas): dental disease/periodontal issues common in small companion breeds; patellar luxation risk; occasional eye issues (e.g., irritation/tear staining) and skin irritation if mats trap moisture; maintain healthy weight to protect joints.
  • Exercise needs: moderate-short daily walks and indoor play usually sufficient; mental enrichment and gentle training benefit this companion-focused breed.】【:】【"】【jsonschema_end

Sexual Dimorphism

Sexual dimorphism is mild, typical of many small companion dogs: males may be slightly larger/heavier-boned and may carry a marginally broader head, but overall appearance differences are subtle compared with wild canids.

  • On average slightly larger or more robust build within the breed's small size range.
  • May show a slightly broader skull/muzzle and thicker neck ruff due to coat fullness.
  • On average slightly smaller and finer-boned.
  • May appear slightly more refined in head and body outline; coat length/texture is otherwise comparable.

Did You Know?

The Bolognese is part of the "Bichon-type" companion dogs-close cousins in look and purpose to breeds like the Maltese and Bichon Frisé.

Its coat is typically solid white and has a soft, fluffy/cottony texture rather than a sleek, flat coat.

Historically linked with the city of Bologna, the breed became fashionable among Italian nobility as a refined household companion.

Bolognese are known for forming strong bonds-many owners describe them as "Velcro dogs" that like to stay close.

Despite the cloudlike coat, many individuals shed relatively little, but the hair can mat easily without routine grooming.

They're small but sturdy for a toy companion breed, often happy with indoor play plus short daily walks.

In modern kennel club systems, they're usually classified among companion/toy breeds (e.g., FCI Group 9: Companion and Toy Dogs).

Unique Adaptations

  • Selective breeding for companionship: compared with the base species (Canis lupus), the Bolognese is strongly tuned to human social cues and household living.
  • Neotenous (juvenile-like) features: small size, rounder head/face, and expressive dark eyes-traits favored in companion breeding.
  • Insulating, continuously growing coat: hair grows and tangles rather than shedding out seasonally like many wild canids; this supports indoor living but demands grooming.
  • Compact size and low exercise demands: adapted to urban/home environments rather than the long-distance roaming typical of wild wolves.
  • Affiliative temperament: reduced drive for hunting/working tasks relative to many dog breeds, with emphasis on calm, steady sociability.

Interesting Behaviors

  • Close-following and lap-seeking: tends to trail family members room-to-room and settle in physical contact.
  • "Watchdog" alerting: may bark at unusual sounds despite being bred primarily for companionship, not protection.
  • Gentle play bursts: short, lively play sessions followed by long cuddle/rest periods typical of many toy companions.
  • People-focused learning: responds especially well to praise-based training and routines (but may become clingy if over-coddled).
  • Sensitivity to separation: can vocalize or show stress when left alone too long; often benefits from gradual alone-time training.
  • Social charm: many are reserved at first with strangers, then warm quickly when introduced calmly.

Cultural Significance

The Bolognese (Canis lupus familiaris) is a small white Italian lapdog from Bologna, once a court companion in Renaissance homes and a status symbol in European portraits. Today it remains a devoted family companion, not a hunting, herding, or guard dog.

Myths & Legends

Renaissance court anecdotes tell of small white "dogs of Bologna" being exchanged as prestigious gifts among nobles, valued as tokens of favor and diplomacy.

In European art tradition, lapdogs-often small white companions like the Bolognese-appear beside sitters as symbols of fidelity and domestic devotion, a visual "story" repeated in portraits across generations.

Naming lore ties the breed's identity to Bologna itself: the "Bolognese" was remembered as the city's signature little companion, a living emblem carried into other courts and households.

Household superstition in parts of Europe held that keeping a gentle lapdog close helped preserve harmony in the home-its constant presence interpreted as a sign of steadfast affection and good fortune.

Behavior & Ecology

Social Pack Group: 3
Activity Diurnal, Cathemeral
Diet Omnivore Highly palatable, animal-protein-forward small-breed diet (e.g., poultry or fish-based); many individuals strongly prefer soft, aromatic foods over large dry kibble.

Temperament

Affectionate, people-oriented companion; frequently described as a 'velcro' dog (breed distinction vs. base canid independence and cooperative hunting focus).
Gentle and playful; enjoys close contact (lap-sitting, following from room to room) and thrives on routine social interaction.
Alert but typically not aggressive; may be reserved with strangers without early, positive socialization.
Sensitive to harsh handling; responds best to reward-based training and calm household structure.
Moderate exercise needs: short walks and indoor play usually sufficient, but benefits from daily mental enrichment (puzzle toys, brief training sessions).
Potential for separation anxiety or nuisance barking if under-exercised, under-enriched, or left alone for long periods.
Common small-breed management concerns: dental disease risk (needs frequent tooth brushing), and possible house-training difficulty if consistency is lacking.
Health concerns seen in the breed/similar toy companion types can include patellar luxation, Legg-Calvé-Perthes disease, eye disorders (e.g., cataracts/progressive retinal atrophy in some lines), and skin/ear sensitivities; responsible breeding and regular vet screening are important.
Care requirements: high grooming needs due to long coat (regular brushing/combing to prevent mats, routine bathing and trimming around eyes/paws); keep ears clean/dry and nails short for comfort and mobility.

Communication

Alert barking (often in response to doorbells/novel sounds); can be amplified if anxious or under-socialized.
Whining/whimpering to solicit attention or indicate discomfort/stress.
Soft yips during play or when excited.
Low growls as a warning if cornered or guarding valued resources Less common with good socialization
Proximity-seeking and following behavior (shadowing primary person); leaning or climbing into laps to maintain contact.
Pawing, nudging, and licking to request interaction or reassurance.
Facial gaze/eye contact used heavily with humans (attention-checking, 'asking' behavior), reflecting companion-breed selection.
Tail carriage and wag style signaling arousal/comfort; small, quick wags often during greeting.
Ear and body posture shifts (freezing, crouching, tucked tail) indicating uncertainty; important for early detection of stress in this sensitive breed.
Scent marking is present but typically reduced/managed in household settings Especially with neutering and training

Quick Take

  • To reach the 1200 recording milestone, the breed survived the Renaissance era collapse.
  • A specific 4-month window marks the onset of critical thigh bone vascular issues.
  • Surprisingly, this hypoallergenic breed requires more grooming than its shedding cousins.
  • The scouting and importation by Liz Stannard was required for the 2002 Crufts debut.

Bolognese is part of the Bichon group, meaning they are cousins to Bichon Frises, Maltese, Lowchens, Havanese, and Coton de Tulear. Bolognese dogs get their name from Bologna, a city in Italy. It is believed that the breed was created in Bologna. The first recording of this breed was in the year 1200.

Bolognese were bred in Italy to be companion dogs and truly do make great companions. These dogs are loving, sensitive, and playful. They make great family dogs for households with older children.

History and Origins

The Bolognese breed of dog has a long history that dates back to the 11th and 12th centuries in Bologna, Italy. It grew in popularity among the nobility during the Renaissance era, and King Umberto gave one as a birthday present to Princess Jose of Belgium. Additionally, in 1668, Cosimo de Medici sent eight Bolognese to Brussels as gifts to several wealthy and influential families.

As the nobility fell away, the Bolognese dog breed almost disappeared. Fortunately, some breeders in Europe, particularly Gian Franco Giannelli from Italy, worked to preserve the breed, and it began to regain its popularity. Liz Stannard imported the breed to England in 1990, and it was first exhibited at shows in Imported Register classes. By 2001, it had its own classes at all shows and made its debut at Crufts Dog Show in 2002.

Size and Weight

The Bolognese is a toy dog breed. Males and females are roughly the same size. They are generally between 10 and 12 inches tall and weigh between 5.5 and 9 pounds. At three months old, puppies typically weigh between 3 and 5 pounds. When they are six months old, puppies weigh between 4.5 and 8.8 pounds. Most Bolognese dogs are fully grown by the time they are nine months old.

Common Health Issues

Overall, these are healthy dogs. However, there are a few common health concerns that you should be on the lookout for in your dog.

Like other small dogs, dental issues are a common problem. Scheduling regular cleanings and brushing your dog’s teeth a few times a week will be important to prevent too much tartar buildup, diseases, or the need for tooth extractions.

Another common disease among these dogs is Legg-Calve-Perthes disease. In this condition, the amount of blood that is able to reach the thigh bone is less than it should be. This causes the thigh bone to shrink, which can cause a Bolognese to limp. Typically, you’ll begin seeing signs of this when a puppy is between the ages of 4 and 6 months old. This condition can be treated by surgery.

Hip dysplasia also affects some Bolognese dogs. This is a genetic condition in which the dog’s thigh bone doesn’t connect with its hip bone correctly. The two bones rub together, which can become painful and may cause a dog to start to limp.

Temperament and Behavior

These dogs have very devoted and sensitive personalities. They are relatively easy-going and are happiest when they are with their family; they make great companion dogs. If left alone, a Bolognese can develop separation anxiety and engage in destructive behavior.

While they are very loving, these dogs can also exhibit stubborn traits, which can make training them a bit of a challenge. They are good with children but will do best in a home with older children who are able to appropriately interact with dogs, so they don’t accidentally injure the small Bolognese.

How to Take Care of a Bolognese

There is a lot that makes the Bolognese a very unique dog breed. The care you will need to provide a Bolognese will be different from what dogs of different breeds require. Keeping the nutritional needs, health concerns, and other factors in mind when thinking about how you’ll care for your Bolognese dog is important.

The Best Dog Food

Since this is a toy dog breed, they will not need large amounts of food. However, they do have a fast metabolism, so it will be important to choose foods that are specially formulated for toy breeds. Always choose high-quality food from a reputable company to protect your dog’s health. If you decide you want to provide your dog with homemade meals, be sure to consult with your vet to make sure you are including all the nutrients your dog needs.

Some owners also choose to feed their dogs a raw diet. Raw diets include fish and meat. If you choose to go this route, be prepared to put in a little more work when preparing and planning your dog’s meals. Or, try a freeze-dried kibble infused with raw protein. Especially for small dogs that can get dental issues, crunchy, dry kibble is best.

The food a Bolognese eats should be high in both fat and protein. When looking for puppy food, you should also look for a special Omega-3 called Docosahexanoic Acid (DHA). This will help make sure the puppy develops properly.

Maintenance and Grooming

These dogs are known for their fluffy white coat. While their hair doesn’t shed, and they are a hypoallergenic dog breed, they are a pretty high-maintenance dog. Their white curly hair will require frequent brushing and bathing to keep it clean and well-maintained. Ideally, you will want to brush your dog three or more times every week. You may also want to take them to a groomer to keep their coat shorter for easier maintenance, or consider trimming them yourself.

Their nails should be trimmed once every month. You should also regularly check their ears to look for dirt or buildup. As a toy dog breed, Bolognese may be more prone to dental issues, so be sure to brush their teeth on a regular basis, too.

Training

Bolognese is an intelligent dog breed, which makes them relatively easy to train. Positive reinforcement training methods will be most successful with this breed. However, they may become easily bored if you are too repetitive. Adding some variety to your training can help it to be more successful.

Exercise

Bolognese dogs do not require nearly the amount of exercise that some other breeds need. Most times, they will be content hanging out with their owners in the house. However, it is important to take them out for a walk every day for about 20 to 25 minutes.

Puppies

Because of their small size, you will want to be especially careful with your Bolognese puppy to avoid accidentally injuring them. It will also be important to begin training your new puppy as soon as you bring them home.

Puppies have very small stomachs, so they will need to eat smaller meals more frequently throughout the day. Puppies between the ages of 8 and 12 weeks should eat four meals each day, and puppies between the ages of 3 and 6 months should eat three meals each day. By the time your dog is 6 months old, you should be able to switch to feeding them twice a day.

With Children

A Bolognese can make an excellent family pet. Bolognese are loving and enjoy spending time with the people in their family. However, they are best suited for families that no longer have toddlers around the home. Young children who haven’t yet learned how to appropriately interact with a dog could injure a small dog like a Bolognese. It is always important to supervise children when they are around a Bolognese to prevent an accidental injury to either the child or the dog.

It is necessary to supervise young children around dogs until they learn to be gentle with their furry family member.

Dogs similar to the Bolognese

Bichon Frises, Maltese, and Havanese are three dog breeds that are similar to these dogs.

  • Bichon Frise: Bichon Frises and Bolognese dogs are both small, white, fluffy dogs. Both breeds are affectionate and may develop separation anxiety if left alone for too long. A Bichon Frise is larger than a Bolognese, though. The average weight of a Bichon Frise is 12-18 pounds, while the average weight of a Bolognese is 6-10 pounds.
  • Maltese: Maltese and Bolognese dogs both originated in Italy. They both have white coats that do not shed. Both Maltese and Bolognese are intelligent and highly trainable breeds. Both breeds are very social and affectionate.
  • Havanese: A Havanese is a companion dog breed, like a Bolognese. Bolognese are all white in color, but Havanese dogs may be white, black, reddish-brown, or other colors. Both breeds are easy to train and have a pretty strong impulse to protect their territory.

Bolognese Dog FAQs (Frequently Asked Questions)

Buying a purebred Bolognese can be quite expensive. These dogs can cost between $1,800 and $2,500. If you find a Bolognese from a shelter or a rescue organization, the amount you’ll pay will be significantly less, and will likely cost a few hundred dollars to cover the vaccination fees and application costs.

After you have budgeted for what you’ll need to pay to bring home a Bolognese, you will also need to make sure you have money to cover veterinary bills, training, food, supplies, and toys for your dog. The first year owning your dog will likely be the most expensive, and you could end up spending over $1,000. For the subsequent years that you own your dog, you’ll want to budget between $500 and $1,000 to cover expenses.
