Thinking about getting a King Charles dog? Before you fall for those big brown eyes and floppy ears, there are a few things you need to know about this sweet companion. This breed may look like royalty, but their habits might surprise you—especially if you’re a first time dog owner in the USA.
Whether you live in a suburban home or a cozy apartment, the King Charles dog—also known as the Cavalier King Charles Spaniel—has become one of America’s favorite lap dogs. But beneath their fancy appearance lies a playful, quirky personality with habits you didn’t know about.
Let’s get to know the most surprising traits of this lovable breed and how to adapt your home, lifestyle and expectations.
Meet the King Charles Dog Breed
The King Charles dog, often confused with its cousin the Cavalier King Charles Spaniel, is an affectionate, toy-sized companion dog with royal roots. While many use the names interchangeably, some kennel clubs make a distinction between the Cavalier (larger, longer nose) and the English Toy Spaniel (flatter face, smaller frame).
Recognized by the American Kennel Club (AKC) in the Toy Group, this breed is known for:
- Floppy ears and tail
- Big brown eyes
- Gentle, loving nature
- 12–18 pounds
- 12–14 years
In recent years their popularity in the USA has skyrocketed because of their size, low aggression and suitability for families, seniors and city dwellers.
King Charles Dog vs Cavalier Spaniel: What’s the Real Difference?
Before we get into this breed’s quirks, let’s clear up one of the most common misconceptions: Is the King Charles Dog the same as the Cavalier King Charles Spaniel?
The short answer is no—they are closely related but recognized as different breeds with different features, personalities and breed standards.
Shared Royal Ancestry, Split Personalities
Both dogs descend from beloved toy spaniels of British royalty in the 17th century. However, in the 20th century selective breeding led to a split:
- The Cavalier King Charles Spaniel was bred to look like the original royal spaniels in old paintings—longer nose, larger body.
- The King Charles Spaniel, known as the English Toy Spaniel in the USA, has a flatter face and smaller frame.
Key Differences at a Glance
| Trait | Cavalier King Charles Spaniel | King Charles Spaniel (English Toy Spaniel) |
| Size | 13–18 lbs | 8–14 lbs |
| Muzzle Shape | Long and tapered | Very flat (brachycephalic) |
| Temperament | Outgoing, energetic | Quiet, reserved |
| Head Shape | Flat with gentle stop | Dome-shaped head |
| Ears | High-set and feathered | Low-set, closer to the cheeks |
| Exercise Needs | Moderate to high | Low to moderate |
| Health Focus | Heart health (mitral valve disease) | Breathing issues (due to flat face) |
Popularity in the USA
In the United States, the Cavalier King Charles Spaniel is far more common, particularly among families, apartment dwellers, and therapy dog seekers. Their balanced temperament and sociable energy make them a favorite across states—from California to New York.
The English Toy Spaniel (King Charles Spaniel) remains a rarer breed, but cherished by those who value a more laid-back and regal demeanor.
✅ Which One Is Right for You?
| Want a dog that is… | Go with… |
| Friendly, active, and great with kids | Cavalier King Charles Spaniel |
| Quiet, dignified, and happy to lounge | King Charles Spaniel / English Toy |
| Easier to train and bond with all ages | Cavalier |
| More independent, good for low-energy homes | English Toy |
Understanding the difference helps you make an informed decision when adopting or purchasing. Many American families choose Cavaliers for their playful nature, while some city dwellers prefer the calmer, quieter English Toy variety.
✅ Now that we’ve cleared up the breed confusion, let’s explore the surprising habits that make the King Charles dog truly unique…

- Preventing behavior problems
- Avoiding health risks
- Training effectively
- Matching lifestyle
Let’s get into the real life quirks that make this breed both adorable and sometimes confusing.
Now that we’ve covered the breed’s history and how it compares to other dogs, let’s get into the quirks that make the King Charles dog truly one of a kind.
9 Surprising Habits Every King Charles Dog Owner Should Know
1. They Love Lap Time—But Aren’t Lazy
Yes, they’re cuddly but don’t mistake them for couch potatoes. King Charles dogs need moderate daily activity and will happily join you on short walks, backyard zoomies or living room fetch.
Tip: 30-45 minutes of light activity a day to prevent weight gain and boredom.
2. They’re Velcro Dogs—Expect Constant Companionship
These dogs are called Velcro dogs for a reason. They stick to their owners and don’t like to be alone for long periods. Left alone too much they can develop separation anxiety.
Pain Point Solved:
- Crate training with calming aids
- Doggy daycare for busy owners
- Treat puzzles to keep them occupied
3. Snorting and Snoring Comes with the Package
Some King Charles dogs especially those bred closer to the flat faced English Toy Spaniel lineage have shorter muzzles. This can lead to mild snoring, snorting or even breathing challenges.
What You Can Do:
- Keep them cool in the summer
- Monitor respiratory signs during play
- Raised bowls to ease feeding
4. They Overheat in Warm Climates
With their thick coat and sometimes brachycephalic features these dogs are not built for high heat. In places like Florida, Texas or California extra care is needed.
USA Tip:
Walk them early in the morning or after sunset in the summer. Avoid hot pavements and consider a cooling vest.
5. Unmatched Emotional Intelligence
King Charles dogs are incredibly intuitive. They often mirror your emotions and offer comfort during tough times, making them excellent therapy dogs.
Example:
Many American hospitals and senior care homes use Cavaliers as therapy dogs due to their gentle nature and emotional awareness.
6. They Get the Zoomies—Indoors
Don’t let their small size fool you. Cavaliers often experience spontaneous “zoomies,” especially in the evening. This is a sign of pent-up energy and excitement.
Quick Fix:
Create a safe indoor play area with rugs and no sharp furniture edges. A short burst of fetch or chase-the-ball will help them settle.
7. Fussy Eaters with a Sensitive Gut
King Charles dogs can be particular about their food, and they’re prone to food sensitivities that cause upset stomachs or skin issues.
Vet-Recommended USA Brands:
- Hill’s Science Diet Small Breed
- Royal Canin Cavalier King Charles formula
- Wellness CORE Grain-Free Small Breed
Avoid table scraps and introduce new foods gradually.
8. Gentle with Kids—But They Must Be Socialized Early
These dogs are fantastic with children, but they do best when raised in a social setting from a young age. Otherwise, they may become timid or overly attached to one person.
Family Tip:
Teach young kids how to handle small dogs gently. Encourage gentle play and never allow tail-pulling or rough housing.
9. Obsessed with Routine and Attention
King Charles dogs thrive on routine—feeding time, walks, bedtime. A sudden change in routine can cause stress or confusion.
Helpful USA Owner Tip:
Use a pet scheduling app like PupTox or Barkly to track feeding, medication, and walk times, especially if multiple people care for the dog.
✂️ How to Groom a King Charles Dog at Home: Pro Tips for a Healthy Coat
While their silky, feathered coats are one of the King Charles dog’s most beautiful features, they also require regular grooming to stay healthy and mat-free. Luckily, you can manage most of their grooming needs at home with the right tools and a bit of patience.
Here’s how to keep your King Charles dog’s coat in top shape:
1. Brush 3–4 Times a Week
This breed has a medium-length, double-layered coat that tangles easily—especially behind the ears, under the legs, and around the tail.
Brush type:
Use a slicker brush or pin brush for daily maintenance. For deeper tangles, use a steel comb.
2. Bath Once Every 4–6 Weeks
Too much bathing can strip their coat of natural oils, but infrequent bathing can lead to odor and dandruff.
Pro tip for USA climates:
In humid states like Florida or Louisiana, consider using a gentle, anti-fungal dog shampoo to prevent skin irritation.
✂️ 3. Trim Feet, Ears & Sanitary Areas
While Cavaliers don’t need full haircuts like Poodles, a hygiene trim helps avoid matting and buildup.
What to trim:
- Feathering around feet and paws
- Fur under the tail (sanitary trim)
- Long hairs around ears (to reduce ear infections)
4. Check and Clean Ears Weekly
Their floppy ears trap moisture, which can lead to infections.
Cleaning routine:
Use a vet-approved ear rinse and cotton balls. Avoid Q-tips, which can damage the ear canal.
✂️ 5. Nail Trimming Every 3–4 Weeks
If you hear a clicking sound when they walk, it’s time to trim. Overgrown nails can lead to joint strain.
Tool:
Use a dog nail grinder or clippers with a safety guard.
Grooming Summary for USA Owners:
| Task | Frequency | Tools Needed |
| Brushing | 3–4 times/week | Slicker brush, metal comb |
| Bathing | Every 4–6 weeks | Gentle dog shampoo, warm water |
| Nail Trimming | Every 3–4 weeks | Dog nail grinder or clippers |
| Ear Cleaning | Weekly | Vet-recommended ear rinse, cotton |
| Feather Trimming | Monthly or as needed | Scissors, thinning shears |
Regular grooming doesn’t just make your King Charles dog look good—it also prevents painful mats, infections, and discomfort. Start slow, reward with treats, and your dog may even enjoy the routine.
Do Cavalier King Charles Spaniel Dogs Shed?
Yes, Cavalier King Charles Spaniel dogs do shed, but it’s considered moderate and manageable compared to high-shedding breeds like Huskies or Golden Retrievers.
These dogs have a soft, silky double coat that naturally sheds year-round, with slight increases during seasonal changes in spring and fall.
How to Manage the Shedding:
- Brush 3–4 times a week to remove loose hairs and prevent matting.
- Use a slicker brush or a deshedding comb to reach the undercoat.
- Bathe every 4–6 weeks with a shedding control shampoo.
- Maintain a balanced diet with omega-3s to support coat health.
Although Cavaliers aren’t hypoallergenic, their shedding is light enough for most households and apartment dwellers in the USA.

- Live in an apartment or condo
