The Cavalier King Charles Spaniel (also known as CKCS) is a sweet, affectionate dog that makes an excellent pet. These small spaniels are playful and active, making them great companions for first-time dog owners or busy individuals who want to get out and exercise more.
But like any breed, the CKCS has its own set of pros and cons, depending on your lifestyle and expectations. So, before you adopt one, you should understand what owning this type of spaniel entails. This guide will walk you through the advantages and potential challenges of this breed before you make the decision to bring one home for your family.
The Pros of Cavalier King Charles Spaniels
1. Great for Many Purposes
CKCS are beautiful dogs with balanced and affectionate personalities. They not only make great family pets and are great with kids, but they also make excellent therapy dogs. If you’re looking for a relaxed lap dog for those evenings and/or one that doesn’t require a lot of daily activity, consider this breed.

2. Easy to Groom
These dogs are also easy to groom. They are mild to moderate shedders, and their coat can be kept in good condition with weekly grooming. This is a plus if your dog doesn’t shed much because you won’t have to clean up much hair. Talk about easy maintenance!
3. Easy to Train
CKCS are super intelligent, which makes them easy to train. They’re quick thinkers and are always eager to please their owners. This makes them a great dog for first-time owners or owners who have more than one dog to take care of.

4. Moderate Exercise Needs
Cavalier King Charles Spaniels need at least 30-60 minutes of physical activity each day to stay healthy and happy. They love long walks and play sessions and will gladly join you on outdoor adventures. That said, they’re quite adaptable and can handle a flexible routine, as long as they get enough daily movement and a chance to stretch their legs more on weekends.

5. Easy-Going Personality
CKCS aren’t typically or overly aggressive and generally have a laidback personality, something that makes them popular with older owners. They’re affectionate pets and make for the perfect lap dog. They’re also good for low-mobility owners.
The Cons of Cavalier King Charles Spaniels
1. Higher Risk of Heatstroke
The Cavalier King Charles Spaniel is considered a brachycephalic (short-nosed) breed. This means their head and airway structure can make it harder for them to cool down efficiently through panting, unlike dogs with longer noses. As a result, they may be more prone to heat-related issues, especially in hot or humid conditions.

2. Prone to Syringomyelia
Cavalier King Charles Spaniels are unfortunately prone to a condition called Syringomyelia, which causes abnormal pockets of fluid to build up in the spinal cord, typically in the neck. Caused by a congenital malformation of the skull, the common signs of this condition include pain, repeated scratching, or rubbing at the neck.
3. Cardiac Disease is Common
Mitral Valve Disease, a condition where the valve between the upper and lower chambers in the heart’s left side begins to leak, is also common in Cavalier King Charles Spaniels. Generally spotted as a heart murmur or abnormal heart sound, this condition can progress to heart failure, though it is generally manageable with medication.

Should You Adopt a Cavalier King Charles Spaniel?
Cavaliers make great pets for many different types of people. If you’re interested in adopting a CKCS, there are a few things you should consider first.
Cavaliers have moderate exercise needs, but still need around an hour of daily activity, whether through walks, playtime, or outdoor adventures. If you live in a hot or humid climate, you’ll need to adjust your routine to avoid overheating. Early mornings or late evenings are ideal for walks. They are prone to certain health problems, so regular vet checkups are essential to monitor their health.
Cavaliers are known for their close bond with their humans and often prefer to sleep near (or in bed with) their favorite people. If you or your partner prefer pets to sleep elsewhere, this may be something to consider.
If you’re prepared to meet their needs—emotionally, physically, and medically—a CKCS can bring a great deal of love, joy, and companionship into your life.

How to Find a Reputable Cavalier King Charles Spaniel Breeder
Many people choose to buy Cavalier King Charles Spaniels from reputable breeders. If you prefer, you can look for a CKCS at your local rescue organization or shelter. You can also look for a breed rescue organization if you decide to adopt a dog that isn’t a CKCS.
Here are a few things to keep in mind when looking for a rescue organization or shelter:
- Reputable rescue organizations and shelters screen potential owners. This means you’ll likely have to provide documentation proving that you’re a suitable owner before the organization will let you adopt a dog.
- They are careful about where their dogs go. They usually only adopt dogs to people in the same state. If you want to adopt a dog from a rescue organization in another state, you’ll have to make arrangements to fly or drive the dog home with you.
- Reputable rescue shelters are happy to answer your questions. If they don’t respond to your emails, phone calls, or letters, you may want to find another organization that has more professional staff and follow-up procedures.

Conclusion
The Cavalier King Charles spaniel is a versatile breed that excels in many settings, including at home as a family pet, companion, and therapy dog. This breed is intelligent and makes a great pet for anyone who wants an energetic, highly social, and fairly active dog.
They can thrive on a routine schedule but also enjoy a more laidback approach. While they can do well as the only dog in the household, many enjoy the companionship of another canine. They are also known for being good with cats as long as they get the right socialization. Another consideration is that they don’t tolerate extreme temperatures well—especially heat or high humidity—and their short snout can make them more prone to respiratory issues.

Hello Maddline,

Thank you. Very helpful. I’ve had small poodles for decades and recently bought a Cavapoo. She seems relatively low energy compared to my Poodles; now I understand why. She loves cold weather but warmer weather not so much. Thanks to you I’ll watch her more carefully as spring turns to summer.
Thanks Judith—we're glad you liked it. Congratulations on your new Cavapoo, how exciting! It sounds like she is in good hands with all of your experience. 🙂
