Cava-Shell
The Cava-Shell is a cross between the Cavalier King Charles Spaniel and the Shetland Sheepdog. Because each hybrid inherits a unique combination of traits from both parents, we recommend thoroughly researching both breeds before choosing a Cava-Shell. Pay special attention to temperament, health issues, and care requirements, as your dog may express characteristics from either parent breed.
Cavalier King Charles Spaniel
The Cavalier King Charles Spaniel is a small, elegant toy spaniel that stands between 12 and 13 inches tall at the shoulder and typically weighs between 13 and 18 pounds when fully mature. This breed possesses a well-balanced, graceful build with a slightly rounded skull, a full muzzle, and a gentle, sweet expression that has earned them the description of having a melting look in their large, round, dark brown eyes. The body is slightly longer than it is tall, with a level topline and moderate bone structure that gives the breed substance without appearing heavy or coarse. The ears are set high, long, and covered with abundant silky feathering that frames the face beautifully and accentuates their gentle expression. The coat of the Cavalier King Charles Spaniel is one of its most distinctive features, consisting of medium-length, silky fur that can be slightly wavy but never curly. Feathering appears on the ears, chest, legs, and tail, adding elegance to the breed's appearance. The breed standard recognizes four color varieties: Blenheim, which features rich chestnut markings on a pearly white background, often with a characteristic lozenge-shaped spot on top of the head; tricolor, consisting of jet black and white with rich tan markings over the eyes, on the cheeks, inside the ears, and under the tail; black and tan, which displays jet black with bright tan markings in specific locations; and ruby, a solid rich reddish-brown throughout. All colors should display clear, well-defined markings without excessive ticking. Additional distinguishing physical characteristics include the moderately long neck that flows smoothly into well-laid-back shoulders, compact feet with well-cushioned pads, and a tail that is carried happily but never much above the level of the back. The tail is well-feathered and may be docked in countries where this practice remains legal, though many breeders now leave tails natural at their full length. The gait is free-moving and elegant, with good reach and drive. The overall impression should be of an active, graceful, and well-balanced dog with a gentle expression that reflects the breed's sweet and affectionate temperament, combining royal elegance with sporting character.
Key Characteristics
Temperament Temperament Temperament Temperament Temperament Temperament Cavaliers are known for their sociable nature with other dogs, pets, and people of all ages, including children. They rarely display aggression and are typically welcoming to strangers, making them poor guard dogs but excellent family pets. Their gentle, patient demeanor makes them particularly suitable for households with young children, though interactions should always be supervised to prevent accidental injury to the dog. These spaniels are often described as having an intuitive ability to sense their owner's emotions, providing comfort during difficult times.
Health Considerations Health Considerations Health Considerations Health Considerations Health Considerations Health Considerations Other health issues common to the breed include hip dysplasia, which affects approximately one in four Cavaliers, patellar luxation, various eye conditions including cataracts and retinal problems, and primary secretory otitis media, often called glue ear, affecting up to thirty percent of the breed. Many Cavaliers also exhibit giant platelet syndrome, where blood tests show abnormally large platelets and seemingly low platelet counts, though this is typically benign and does not cause health problems. The breed's average lifespan ranges from twelve to fifteen years, though those significantly affected by heart disease may have shorter lives. Responsible breeders screen their breeding stock for heart conditions, syringomyelia, hip dysplasia, and eye problems.
Shetland Sheepdog
The Shetland Sheepdog, affectionately known as the Sheltie, is a small to medium-sized herding breed that stands between 13 and 16 inches at the shoulder and typically weighs 15 to 25 pounds. While they bear a striking resemblance to Rough Collies in miniature, Shelties are a distinct breed developed under unique circumstances on the harsh Shetland Islands of Scotland. The breed possesses an elegant, well-proportioned build with a refined wedge-shaped head that appears long and blunt when viewed from the side. The almond-shaped eyes are medium-sized, set somewhat obliquely, and convey intelligence and alertness, while the small ears are carried three-quarters erect with the tips folding forward. The expression is gentle yet keen, reflecting the breed's combination of sensitivity and alertness that made them excellent herding dogs. The Sheltie's double coat is one of its most magnificent features, consisting of a long, straight, harsh outer coat and a short, dense, furry undercoat that together provide excellent weather protection. The abundant mane and frill around the neck and chest give the breed a noble, lion-like appearance, while the forelegs and hind legs above the hocks are heavily feathered. Accepted coat colors include sable ranging from golden to deep mahogany, tricolor featuring jet black with rich tan and white markings, blue merle with silvery blue-gray and black mottling, black and white, and black and tan. White markings typically appear as a blaze, collar, chest, legs, and tail tip, creating the classic Sheltie appearance. The Shetland Sheepdog moves with a smooth, effortless gait that demonstrates excellent reach in front and strong drive from behind, reflecting its herding heritage. The body is slightly longer than tall, with a level back, well-sprung ribs, and a deep chest that reaches to the elbows. The tail is sufficiently long to reach the hock and is carried low when the dog is at rest, rising slightly when alert but never curving over the back. Overall, the Sheltie presents a picture of grace, symmetry, and agility combined with strength sufficient for the demanding work of herding sheep across rugged terrain.

Shelties are sensitive dogs who pick up on their owners' emotions and moods, making them wonderful companions for those who appreciate a deeply connected relationship with their pet. They generally get along well with children and other pets when properly socialized from puppyhood, though their reserved nature means they benefit from gradual introductions to new people and situations. Their combination of intelligence, loyalty, playfulness, and affection has made them consistently popular family pets.
Health Considerations Health Considerations Health Considerations Health Considerations Health Considerations Health Considerations Other health issues affecting Shetland Sheepdogs include hip dysplasia, patellar luxation, thyroid disorders particularly hypothyroidism, and gallbladder mucoceles. The breed also carries the MDR1 gene mutation, which causes sensitivity to certain medications including ivermectin and other common drugs. Dogs with this mutation can experience severe, potentially fatal reactions to these medications, so testing is recommended and results should be shared with veterinarians. With proper care, health screening, and responsible breeding practices, Shetland Sheepdogs typically enjoy lifespans of twelve to fourteen years. Regular veterinary checkups, appropriate exercise, and maintaining a healthy weight contribute significantly to longevity and quality of life.
Important to Remember
Each hybrid dog is unique and may inherit any combination of traits from either parent breed. The information above represents the characteristics of the purebred parent breeds. Your Cava-Shell may favor one parent over the other or display a blend of both. We strongly encourage you to read the complete breed profiles for both the Cavalier King Charles Spaniel and Shetland Sheepdog to fully understand the range of possible temperaments, health concerns, and care requirements.
