Cavalier King Charles Spaniels are popular family pets – but they’re not hypoallergenic dogs.
In fact, there is no such thing as a completely hypoallergenic dog, but some breeds are better than others for owners who suffer with an allergy to dogs.
The odds are that you’ve encountered a Cavalier King Charles Spaniel at some point in your life.
The toy breed are the seventh most popular dogs in the United Kingdom and the 19th most popular dogs in the United States.
Cavalier King Charles Spaniels make great family pets because they’re affectionate, docile and eager to please.
They’re quick to learn new commands, tend to get along with other dogs and don’t bark a lot.
But one of the most common questions about the Cavalier King Charles Spaniel is whether they’re hypoallergenic or not.
In this article, helloBARK! is going to explain what hypoallergenic means, understand whether Cavalier King Charles Spaniel are hypoallergenic and what other breeds are good for allergy sufferers.
According to a report by the American College of Allergy, Asthma, and Immunology, as much as 10 per cent of the US population are allergic to dogs.

But first, let’s take a look at the origins of the ‘CKCS’.

A quick introduction to the Cavalier King Charles Spaniel

The history of the Cavalier King Charles Spaniel can be traced back to Scotland in the 15th century. The ancestors of this breed were thought to have been brought to Scotland from France.
Mary Queen of Scots introduced the dogs to England but it was the Stewarts who helped these toy spaniels to achieve popularity among nobility within the British Isles.
King Charles I and King Charles II were big fans of these dogs, who were often granted access all areas in their palaces.
Duke of Marlborough John Churchill had many chestnut and white King Charles Spaniels and because his residence was called Blenheim Palace, this variety were given the named Blenheim CKCS.
The influx of Asian breeds such as the Pug and Japanese Chin led to interbreeding. As a result, these spaniels started to develop stunted muzzles and domed head.
An American called Roswell Elridge encouraged breeders to revive the old style King Charles Spaniel in 1925. This led to a distinction being made between the King Charles Spaniel and the Cavalier King Charles Spaniel.
The Kennel Club recognised the Cavalier King Charles Spaniel in 1945, before the American Kennel Club granted the breed full status almost 50 years later in 1995.
What does hypoallergenic mean?
Hypoallergenic is referring to something that is less likely to trigger an allergic reaction.
You will often spot this term on skincare and make up, but it can also be used alongside dog breeds.
For people who are allergic to dogs, there is a possibility that some dog breeds could be better suited to people with allergies.
However, the American Kennel Club emphasise that there are no dog breeds that are 100 per cent hypoallergenic. They do list some types of dogs that are less likely to cause an allergic reaction – though.

The Cavalier King Charles Spaniel are not a hypoallergenic dog breed.
However, these dogs can be mixed with some other breeds to create a pup that is better suited to those with a dog allergy.
Often described as a designer breed, a Cavachon, which is a mix of Cavalier King Charles Spaniel and Bichon Frise, is thought to be better suited to those looking for a hypoallergenic dog.
Another mix is a Cavapoo, which is a cross between a Cavalier King Charles Spaniel and a Poodle. A Cavapoo mix could have a curly coat like a poodle or Cavalier King Charles Spaniel’s long, wavy coat.
helloBARK! recommends consulting with your local doctor and your local vet to learn more about coping with a dog allergy and what breeds may be suitable, if any.
Cavalier King Charles Spaniels do shed quite a bit. Regular brushing and grooming is recommended to maintain the quality and shine of their coat. It can help prevent the fur from becoming tangled and matted.
Given they can leave quite a bit of hair behind on clothes and furniture, this could be a problem for allergy sufferers.
The Cavalier King Charles Spaniel has a reputation (unfairly) for being a sometimes smelly dog. They can give off an odour if they haven’t been groomed. Their long coats can pick up bacteria and dirt.
If you do get a bad smell from a CKCS, it could also be bad breath or sign of an infection in their curly ears. It is a good idea to speak to your vet if you have any concerns about your Cavalier King Charles Spaniel’s odour.
So, what breeds are hypoallergenic dogs?
The American Kennel Club do recognise a number of breeds as better suited for people with allergies.
The AKC state on their website: “While there are no 100% hypoallergenic dogs, there are many breeds that do well with allergy sufferers. Dander, which is attached to pet hair, is what causes most pet allergies in humans and these dogs have a non-shedding coat that produces less dander.”
