The Cav is small but doesn't feel fragile. There's a solidness to a well-built Cavalier that surprises people who expect something more delicate. Weighing between 12 and 18 pounds and standing 12 to 13 inches at the shoulder, these dogs have enough substance to hold up to real daily life while remaining genuinely portable and apartment-friendly.
The head is distinctive and immediately recognizable. The skull is slightly rounded but not domed, with large, round, dark eyes that are set well apart and carry the gentle, melting expression the breed is famous for. It's not an accidental look - the round eyes, the soft expression, the way the ears frame the face - all of it was selected for because people responded to it. The muzzle is full, tapered, and about one and a half inches in length. The nose is black, and the overall facial impression is of warmth and openness rather than alertness or suspicion.
The ears are long, set high, and covered in silky feathering that hangs alongside the cheeks. Together with the large eyes, they create the breed's characteristic look of gentle attentiveness. The neck is moderately long and arched, flowing into well-laid-back shoulders that give the breed its smooth, effortless-looking front movement. The body is compact and well-sprung through the ribs, with a level back and a moderately rounded rump.
The coat is one of the breed's most appealing physical qualities - silky in texture, lying flat or with a slight wave but never curly, and medium in length across the body. Feathering appears on the ears, the chest, the undersides of the legs, and the tail, giving the dog an elegant, flowing silhouette in motion. The four recognized colors each have their own character: Blenheim - chestnut and white with the distinctive lozenge marking on the forehead - is the most common and historically significant. Tricolor combines black, white, and tan. Black and Tan features a rich black coat with tan markings above the eyes, on the muzzle, chest, and legs. Ruby is a solid warm chestnut without white.
In motion, the Cav moves freely and gracefully with good reach in front and drive from behind. The tail is carried level with the topline or slightly above in action and should not be carried high over the back. The overall picture in motion is of a joyful, flowing little dog that clearly enjoys moving - which is an accurate reflection of this breed's personality.
One physical quality worth understanding as a prospective owner is the breed's muzzle length. The Cavalier has a fuller muzzle than its flat-faced cousin the King Charles Spaniel, but it is shorter than most spaniel breeds. This means the Cav is not severely brachycephalic - it doesn't have the extreme breathing difficulties associated with English Bulldogs or Pugs - but it is more heat-sensitive than a longer-muzzled dog. On very hot days, outdoor activity should be limited to the cooler morning and evening hours. Panting is this breed's primary cooling mechanism, and a shortened muzzle reduces its efficiency.
Body condition is worth monitoring throughout this breed's life. The Cav can have a tendency toward weight gain if food intake isn't managed thoughtfully, and extra weight on a small frame with documented joint and cardiac concerns compounds those health risks meaningfully. A well-conditioned Cav should have a visible waist when viewed from above and ribs that are easily felt but not prominently visible. Most owners find that measured, twice-daily feedings work better than free-feeding for managing weight over time.
Affectionate With Family
★★★★★
The Cav lives to be close to its people. This is a dog that follows you from room to room, seeks lap time at every opportunity, and is genuinely happiest when physical contact with a family member is available.
Good With Young Children
★★★★★
Gentle, patient, and tolerant, the Cav handles the energy of children well. Their soft temperament makes them a natural fit for family life, though their small size means very young children should always be supervised.
Good With Other Dogs
★★★★★
Cavs are genuinely sociable with other dogs - not just tolerant but actively interested. They tend to make friends quickly and do well in multi-dog households.
Shedding Level
★★★☆☆
Shedding is moderate and consistent year-round. The silky coat releases hair steadily, and regular brushing significantly reduces what ends up on your furniture and clothing.
Coat Grooming Frequency
★★★☆☆
The Cav's silky coat needs brushing three or four times a week to stay tangle-free and healthy. The feathering around the ears and legs is the most prone to matting.
Drooling Level
★☆☆☆☆
Drooling is minimal. The Cav is one of the cleaner small breeds in this regard.
Coat Type
★★★☆☆
The coat is silky and medium in length with graceful feathering on the ears, chest, legs, and tail. It should lie flat rather than curl or wave.
Openness To Strangers
★★★★★
Cavs are notoriously friendly with everyone, often without discrimination. They were bred to be companions, not guardians, and most greet strangers with the same enthusiasm as family members.
Playfulness Level
★★★★☆
The Cav carries a playful energy throughout its life, happily engaging with games, toys, and interactive time. That playfulness is balanced with a calm willingness to settle when the activity winds down.
Watchdog/Protective Nature
★★☆☆☆
The Cav may alert bark but is not a reliable watchdog. Its friendly nature toward strangers limits its effectiveness as a deterrent, which is entirely consistent with the breed's companion purpose.
Adaptability Level
★★★★★
Few small breeds adapt as comfortably to different living situations as the Cav. Apartments, houses, urban settings, rural properties - this dog adjusts well as long as companionship is consistent.
Trainability Level
★★★★☆
Cavs are responsive and willing learners who do well with gentle, positive training approaches. Harsh methods backfire with this sensitive breed; consistent kindness gets real results.
