What are the markings on a Blenheim Cavalier?


The Blenheim Cavalier King Charles Spaniel is one of the most popular colors and patterns of the Cavalier breed. The Blenheim Cavalier is distinguished by its chestnut and white coat markings. While all Blenheim Cavaliers share these defining colors, there can still be variation in the specific markings between individual dogs. Understanding the unique Blenheim pattern can help identify this variety of Cavalier.

Origin of the Blenheim Name

The “Blenheim” name originated from Blenheim Palace in England. Legend has it that King Charles I’s Maltese dog gave birth to puppies at the palace, sparking interest in the new breed. The red and white Cavalier puppies became known as “Blenheim” spaniels after the palace. The name Blenheim has become synonymous with this chestnut and white coat pattern in the Cavalier King Charles Spaniel.

Distinctive Markings

While individual dogs vary slightly, the Blenheim Cavalier has some trademark coat markings that set it apart from the other color patterns. Here are some of the key features:

Chestnut Coloring on the Head

Most prominently, Blenheim Cavaliers have rich chestnut red coloring on their heads. This chestnut red covers the ears, eyes, muzzle and cheeks. The chestnut red may also extend down the neck or as a “thumb mark” pattern on the top of the head. The eyes are framed by the chestnut markings.

White Blaze

A bold white blaze runs down the center of the forehead and muzzle, splitting the chestnut coloring. This wide, narrow blaze is a distinctive feature of the Blenheim. It runs from the top of the head and stops between the eyes or extends down to the nose.

White Neck and Body

The chestnut markings on the head stand out vividly against the pure white of the neck, body and legs. The white background covers the neck, chest, stomach, back and tail. The white fur continues down all four legs.

Chestnut Body Spots

While the overall body is white, Blenheim Cavaliers often have additional small chestnut patches on their body. These spots may appear on the neck, chest, underside, back or hocks. The number, size and location of these spots varies greatly. Some Blenheims may only have a thumb mark while others can have many body spots.

Chestnut ears, eyes, muzzle and cheeks May have small chestnut spots Primarily white with chestnut spots White

Coat Patterns

While all Blenheim Cavaliers share the trademark chestnut and white colors, there can be variation in the specific pattern beyond the basic markings:

Symmetrical Coat Pattern

The ideal Blenheim pattern is symmetrical, with balanced chestnut markings on both sides of the head and evenly distributed body spots. Symmetry demonstrates quality breeding.

Heavily Marked Blenheim

Some Blenheims can be heavily marked, with the chestnut color extending down the neck and covering the ears. They may have large body spots or patches that connect. The white blaze still distinguishes them.

Lightly Marked Blenheim

Conversely, some Blenheim Cavaliers may be very lightly marked with minimal chestnut coloring just on the head and almost completely white bodies. They may only have a small thumb mark on the skull with little body spotting.

Unique Asymmetrical Patterns

It’s not uncommon for Blenheim Cavaliers to have slightly asymmetrical markings with some variation between sides. One ear may have more chestnut than the other. Body spots often differ on each side. No two Blenheim patterns will be exactly the same.

Key Requirements

To be classified as a true Blenheim, Cavalier puppies must meet certain minimum requirements in their markings:

Chestnut on Both Ears

Rich chestnut coloring must be present on both ears. A completely white ear would disqualify it from the Blenheim pattern.


The signature blaze is required. It may vary in width but a white strip dividing the forehead is essential.

Chestnut Spots

At least some minimal chestnut spotting elsewhere on the body beyond just the ears is expected. Solid white with no spots is not considered a true Blenheim.

Color Development

The chestnut and white coat continues to refine as the Blenheim Cavalier matures:

Birth to 8 Weeks

Blenheim puppies are born with their basic markings, though the colors appear paler. The chestnut has a fawn tone and the blaze is a light beige. The true rich chestnut reddish tone develops gradually.

8-12 Weeks

During the 2-3 month stage, the puppy coat is very fluffy. The adult coat begins growing in underneath, with the signature colors becoming more defined. Chestnut markings spread as the white puppy fuzz sheds.

3-6 Months

By 5-6 months old, the mature coat replaces the puppy fur. The colors are fully saturated and the adult coat texture is apparent. The Blenheim pattern is now complete and recognizable.


In adult Blenheim Cavaliers, the chestnut markings are a deep mahogany red tone while the background coat is a stark, bright white. The colors remain stable throughout adulthood with proper care and nutrition. Regular brushing reduces any darkening from dirt or oils.

Common Confusion With Other Markings

The Blenheim pattern is sometimes mixed up with similar chestnut and white coat colors in other breeds or other Cavalier varieties:

Ruby Cavalier

The Ruby Cavalier has a whole body rich chestnut coat with no white markings. It lacks the contrasting white blaze, neck and body fur of the Blenheim.

Tricolor Cavalier

The Tricolor Cavalier has black body markings instead of chestnut. Its signature head pattern has black ears with tan cheeks and eyebrows.

English Toy Spaniel

Some English Toy Spaniels can look similar to Blenheim Cavaliers. However, English Toys have a domed head, longer muzzle and more square body shape. The coat is also flatter.


Papillon dogs have long, fringed erect ears. A red head with white body papillon may seem Blenheim-like but lacks the drop ears and spaniel traits.

Grooming Needs

The Blenheim Cavalier’s moderate-length silky coat requires regular grooming:


Frequent brushing prevents mats and tangles. A pin brush is ideal for working through the feathering and body coat. Regular brushing also helps remove dirt and distribute oils to enhance shine.


Bathe once every 4-8 weeks or when dirty. Overbathing strips the coat of essential oils. Use a moisturizing dog shampoo. Thoroughly rinse and dry the thick coat after.


Trim excess hair between the foot pads if needed for neatness. Avoid trimming the body coat which protects the skin. Trim ear and tail fringe hair only to shape and minimize tangles if desired.

Activity Frequency
Brushing 2-3 times per week
Bathing Every 4-8 weeks
Trimming Just feet and ears if needed

Nail Clipping

Clip nails regularly to prevent overgrowth and splitting. Be careful not to cut too short to avoid hitting the quick. Using nail clippers designed for dogs makes trimming easier.

Common Health Issues

Like all breeds, Blenheim Cavaliers may be prone to certain health conditions. Being aware of them helps provide the best care.

Heart Conditions

Mitral valve disease and other heart problems are potential concerns for the breed. Annual vet exams to check heart health are important.

Luxating Patellas

Loose knee caps or patellar luxation sometimes affects small breed dogs. Mild cases may not need treatment but severe slips require surgery.

Ear Infections

Floppy ears trap moisture, increasing the risk of chronic ear infections. Checking ears weekly and cleaning as needed prevents infection.


Cavaliers love food and treats. Without proper exercise and portion control, they can easily become overweight. Maintain optimal weight to reduce joint and heart issues.

Eye Issues

Some inherited eye disorders like cataracts and retinal dysplasia may be seen. Routine vet eye exams identify any problems early.

Condition Description
Mitral Valve Disease Deterioration of the heart valve
Patellar Luxation Knee cap dislocation
Ear Infections Chronic infected ears
Obesity Being significantly overweight
Eye Issues Cataracts, retinal dysplasia

Ideal Home Life

The affectionate, playful Blenheim Cavalier thrives as a loyal companion and family dog with proper care:

Indoor Housing

The silky coat offers little protection from the elements. Blenheim Cavaliers should live primarily indoors with their family.

Moderate Exercise

They require daily walks and active play but have lower exercise needs than sporting breeds. Avoid too much exercise in heat.

Mental Stimulation

This intelligent breed benefits from training, interactive toys and games. Participating in canine sports provides mental and physical activity.


Early and ongoing socialization ensures friendliness towards people, pets and handling. Cavaliers who meet many people and dogs are outgoing.

Grooming Care

Their long coat needs regular brushing and occasional baths to prevent mats and keep the skin and coat healthy. Trim nails and clean ears too.

Finding a Blenheim Cavalier

Here are some tips for locating a happy, healthy Blenheim Cavalier King Charles Spaniel:

Reputable Breeders

Always buy from responsible breeders who focus on health and good temperament. Ask to meet parent dogs. Avoid pet stores or irresponsible backyard breeders.

Health Certification

Look for camps that test breeding dogs for heart, eye, knee and DNA health conditions and share results. Review health guarantees.

Puppy Temperament

Observe puppies interacting. Pick mellow, friendly puppies rather than very shy or aggressive ones. Have children present to choose a good family dog.


If showing in conformation is important, evaluate structure, gait and movement for correct conformation. Pet owners may focus less on precise breed standards.


Review the breeder contract thoroughly and ask questions. Most reputable breeders will take back dogs at any point if needed.
