The Cavalier King Charles Spaniel is a beloved breed known for its gentle and affectionate nature. They are a small to medium-sized dog with a moderate energy level.
Their weight typically ranges from 10-18 pounds, with a height of 13-15 inches. This compact size makes them an ideal companion for families or individuals living in small spaces.
One of the most distinctive features of the Cavalier King Charles Spaniel is its beautiful, gentle eyes. These sweet eyes are a key characteristic of the breed and are a major reason why they're so beloved by many dog owners.
Their coats are moderately long and require regular grooming to prevent matting and tangling. Regular brushing and occasional trimming can help keep their coat looking its best.

Health Concerns
As you're considering bringing a Cavalier King Charles Spaniel into your family, it's essential to know about the potential health concerns. Nearly all Cavaliers will develop mitral valve disease, a condition that can lead to heart failure, and it's estimated that over half of the breed will have it by age 5.
Heart disease is a leading cause of death in the breed, and it's not uncommon for a 10-year-old Cavalier to have a heart murmur. Veterinary geneticists and cardiologists have developed breeding guidelines to prevent early-onset heart disease, but it's unclear if many breeders follow these guidelines.
Hip dysplasia is another common issue in Cavaliers, and it's not usually evident in X-rays until the dog matures. Hip dysplasia can lead to arthritis and lameness, and in severe cases, surgery may be necessary.

Mitral Valve Disease
Mitral valve disease is a serious health concern in Cavalier King Charles Spaniels, with nearly all dogs eventually developing the condition.
Mitral valve disease is polygenic, meaning it's affected by multiple genes, making all lines of Cavaliers susceptible to the condition.
It's the leading cause of death in the breed, with 42.8% of Cavalier deaths being cardiac related, according to a survey by The Kennel Club of the United Kingdom.

Cancer and old age are the next most common causes of death in Cavaliers, with 12.3% and 12.2% of deaths attributed to these factors, respectively.
The condition can begin to emerge at an early age, with more than half of all Cavalier King Charles Spaniels expected to have mitral valve disease by age 5.
It's rare for a 10-year-old Cavalier not to have a heart murmur, highlighting the prevalence of the condition in the breed.
Veterinary geneticists and cardiologists have developed breeding guidelines to eliminate early-onset mitral valve disease, but it's unclear if many breeders follow these guidelines.
The MVD breeding protocol recommends that parents should be at least 2.5 years old and heart clear, and their parents should be heart clear until age 5.

The Cavalier breed is ranked 78th worst out of 157 breeds for hip dysplasia, according to the Orthopedic Foundation for Animals. The worst affected breeds are the Bulldog, Pug, and Dogue de Bordeaux.
A genetic defect of the femur and knee called luxating patella is a concern for Cavalier owners. This condition is most often observed when a puppy is 4 to 6 months old.
If a Cavalier has a grade 1-2 luxating patella, physical rehabilitation therapy and exercise may reduce the grading and potentially avoid surgery.
Eye Problems
Eye problems are a significant concern for Cavalier King Charles Spaniels, with an average of 30% of all evaluated dogs affected, according to a 1999 study by the Canine Eye Registration Foundation.
Keratoconjunctivitis sicca, or "dry eye", is a common disorder in Cavaliers, caused by an autoimmune reaction against the tear gland, reducing tear production.
This condition can lead to partial or total blindness if left untreated, and requires continual treatment to manage symptoms.

Hereditary cataracts, corneal dystrophy, distichiasis, entropion, microphthalmia, progressive retinal atrophy, and retinal dysplasia are all eye problems that can affect Cavaliers.
The Canine Inherited Disorders Database notes that some of these conditions can decrease or heal over time, but ongoing treatment is often necessary to prevent vision loss.
Continual veterinary care and monitoring can help identify eye problems early on, allowing for prompt treatment and a better quality of life for affected dogs.

Divergence
The Cavalier King Charles Spaniel breed has a fascinating history of divergence from its King Charles Spaniel roots. In 1926, a dog show class prize was offered for the best male and female "Blenheim Spaniels of the old type" with specific characteristics.
Roswell Eldridge's prize was meant to promote a specific type of dog, which was later known as the Cavalier King Charles Spaniel. This effort led to the formation of the first Cavalier club in 1928.
The breed's development was set back significantly during World War II, with many breeding stock being destroyed due to wartime hardship and food shortages. In the Ttiweh Cavalier Kennel, the population of 60 dogs dropped to just three during the 1940s.
The breed was eventually recognized by the Kennel Club in 1945 as the Cavalier King Charles Spaniel, marking a new beginning for the breed.
