You’ve seen them in old oil paintings, perched on velvet cushions next to dukes and duchesses. The brown and white Cavalier King Charles Spaniel—officially known as the Blenheim—is basically the "original" look for this breed. But honestly, if you're looking for one today, there's a lot of noise and a few big misconceptions about what that brown and white coat actually signifies.
It isn't just "brown." It’s chestnut. Or at least, it’s supposed to be.
People often get hung up on the "brown and white" label, but in the world of high-end breeding and kennel clubs, that specific shade of red-toned mahogany is the gold standard. If the brown looks too "muddy" or like a Hershey’s bar, you’re actually looking at a rare, non-standard chocolate variation, not a true Blenheim.
The Marlborough Connection and the "Thumbprint"
The name "Blenheim" isn't just a fancy word. It comes from Blenheim Palace. John Churchill, the 1st Duke of Marlborough, was obsessed with these red and white hunting spaniels. Back in the 1700s, they weren't just lap dogs; they were hardy enough to keep up with a trotting horse.
There is this legendary story—kinda a myth, but sweet—about Sarah Churchill, the Duchess of Marlborough.
The story goes that while she was waiting for news from the Battle of Blenheim, she was so anxious that she kept pressing her thumb against the forehead of a pregnant spaniel. When the puppies were born, they all had a small, reddish-brown spot right where her thumb had been. We call this the "Blenheim Spot" or the "Queen’s Kiss."
Is it genetically required? No. But if you’re at a dog show, judges go crazy for it. It’s like the ultimate "easter egg" of the Cavalier world.
Brown and White vs. Chocolate: A Crucial Distinction
This is where things get a bit messy for potential owners.

A standard brown and white Cavalier King Charles Spaniel (Blenheim) has a pearly white base with rich chestnut markings. They have black noses and dark, soulful eyes.
Then there’s the Chocolate Cavalier.
These guys are technically "purebred" in terms of DNA, but they carry a recessive gene that turns all the black pigment in their body to brown. This means they have:
- A liver or chocolate-colored nose (not black).
- Greenish or amber eyes (not dark brown).
- Light-colored "ruby" markings that look more like milk chocolate.
While they are adorable, the AKC and most international clubs consider chocolate a "disqualifying" color. If a breeder is charging you $5,000 because a chocolate and white pup is "ultra-rare," be careful. Usually, "rare" in the dog world is just another word for "does not meet the health and aesthetic standards we've spent 200 years perfecting."
The Genetics of the Blenheim Coat
If you breed two Blenheims together, you get 100% Blenheim puppies. Period.
It’s a recessive trait (specifically the ee and ss genotypes). Because it’s so predictable, it’s the most common color you’ll see. But just because it's common doesn't mean it's easy to get "right."
Breeders obsess over "break-up." You want the chestnut patches to be well-distributed over the white. If the dog is almost entirely brown with just a tiny white patch on the chest, it’s a "mismarked" Ruby. If it’s almost entirely white with just one brown ear, it’s often called a "clown face."

Why the White Fur is a Magnet for Trouble
Owning a brown and white Cavalier means you are now in a committed relationship with a brush.
That "pearly white" background shows everything. Mud? Yep. Grass stains? Absolutely. But the real enemy is tear staining. Because Cavaliers have those large, slightly protruding eyes, they tear up a lot. On a white muzzle, those tears turn a rusty, crusty brown.
Daily face wipes aren't optional. It’s just part of the deal.
Also, we need to talk about the ears. The chestnut fur on the ears grows long and silky. If they dip those ears into a bowl of wet food, you’re going to have a matted, sticky mess by dinner time. Many owners use "snoods" (basically headbands for dogs) to keep those long ears out of the kibble. It looks ridiculous. Your dog will look like a 1950s housewife in a shower cap. But it works.
Health Realities: It’s Not Just About the Color
I’m going to be real with you: Cavaliers are "heartbreak dogs."
Regardless of whether they are brown and white, tricolor, or solid red, they are prone to Mitral Valve Disease (MVD). By age ten, almost all Cavaliers have some form of a heart murmur.
There’s also Syringomyelia (SM). This is a complex condition where the skull is slightly too small for the brain, causing fluid pockets in the spinal cord. If you see a Cavalier "air scratching" at their neck without touching the skin, that’s a massive red flag.

When you’re looking for a Blenheim puppy, don’t just look at the markings. Don't worry about the "thumbprint" spot first. Ask for:
- An OFA heart clearance (done by a cardiologist, not just a regular vet).
- A recent eye exam (CERF).
- MRI results for the parents (if available) to check for SM.
The Personality Myth
Some people swear that Blenheims are the "sweetest" of the four colors. They say Rubies are feisty and Tricolors are "the thinkers."
Scientifically? That’s nonsense.
A dog's temperament is way more about its parents and its socialization than whether it has brown spots or black ones. However, because Blenheims are the "face" of the breed, they’ve been bred as companion animals for centuries. They are essentially professional snugglers. If you want a dog that will follow you into the bathroom and sit on your feet while you brush your teeth, this is the one.
Finding a "Good" Brown and White Puppy
Don't buy from a pet store. Just don't.
Most pet store pups come from commercial mills where they don't screen for those heart and brain issues I mentioned. Instead, look for a "Preservation Breeder." These are the people who show their dogs and are obsessed with maintaining the health and look of the 18th-century spaniel.
Expect to wait. A good breeder might only have one or two litters a year.
Actionable Steps for New Owners
- Buy a high-quality "slicker brush." You’ll need it to keep the white "feathering" on the legs from turning into a bird's nest.
- Get a shallow water bowl. This helps keep the long chestnut ears dry.
- Find a cardiologist early. Don't wait until your dog is coughing to check their heart. Get a baseline screening around age two.
- Invest in "Angel Eyes" or similar wipes. Start the habit of wiping the white fur under the eyes every single morning to prevent permanent staining.
The brown and white Cavalier King Charles Spaniel is a living piece of history. They are regal, slightly needy, and incredibly beautiful—provided you don't mind a bit of white fur on your black leggings and the occasional "Queen’s Kiss" on your cheek.
