Cavalier King Charles Spaniel Health Issues

One of the leading Cavalier health issues is mitral valve disease, a heart condition that weakens their valves.

Another top Cavalier King Charles spaniel health problem is Syringomyelia (SM). This is a brain and spine condition caused by a deformity in the lower end of the skull. The deformation then squeezes the brain and forces spinal fluids into the spinal cord. Although the symptoms may be mild in some dogs, watch out for paralysis and pain in some limbs.

The last health issue that they are affected by is idiopathic asymptomatic thrombocytopenia. This is an abnormality causing a low platelet count resulting in clotting issues. In other words, your pet will bruise easily.

It doesn’t matter whether you get your puppy from a reputable breeder or take the King Charles Cavalier adoption route. This is because all Cavalier dogs are prone to any of the above-listed diseases. The most important thing is to ensure you consult a vet, and all will be well!


The popularity of the toy King Charles Cavalier dogs dates back to the 16th century. During these times, Charles I reigned as king. He and his son, Charles II, took a liking to a black and tan spaniel toy dog. And this is how the breed earned the royal name.

In the next 200 years, the “royal” toy pups had been crossbred with Asian pugs and Japanese chin. This gave way to a breed with a dome head and flatter face, now called King Charles spaniel dogs.

However, in the 1920s, dog breeders began looking for the “original” King Charles spaniels. The interest became so great for Roswell Eldridge that he offered £25 to get the original toy spaniel in 1926. Roswell was an American breeder interested in toy spaniels with longer faces, flatter heads, and larger sizes.

The lucrative cash reward drove numerous breeders to bring back the “original” dog. Through this revival, the pups earned their current titles—the famous Cavalier King Charles spaniels. By 1928, the first Cavalier club was formed, and these sweet pups soon gained popularity.

Unfortunately, the destructions of World War II (1939 to 1945) led to the disappearance and diminishing of most European dogs. Only 60 Cavalier King Charles dogs were registered with the Cavalier Club during the entire war period.

However, right after the war, breeders tried to increase the numbers. UKC even recognized Cavaliers separate from King Charles spaniels in 1945. By 1956, the dogs had made their way to the US and were recognized by AKC in 1995.
