Cavalier King Charles Spaniel

Complete list of Cavalier King Charles Spaniel health problems

Sadly, the lovely and sweet-natured Cavalier makes my list of the Top Five Unhealthiest Breeds.

No one should acquire a Cavalier King Charles Spaniel unless:

  • they live near a specialist veterinary clinic that includes a board-certified cardiologist and neurologist and
  • they're willing and able to spend lots of money for specialist veterinary care and
  • they're okay with the very real chance that they can lose their beloved dog in middle age.

Heart disease in the Cavalier King Charles Spaniel

With Cavaliers, it all starts with an aggressive form of Mitral Valve Disease, the #1 killer of this breed.

Now, a different form of mitral valve disease is found in many other small breeds. This form comes on slowly, progresses slowly, and is usually very manageable.

People can have mitral valve disease, too – both I and my husband have it. Again, it's mild and easily managed.

But MVD in the Cavalier is very different.

HALF of all Cavaliers will develop MVD by 5 years of age, and virtually ALL (99%) will have it by 10 years of age.

MVD is a true epidemic in the breed, dragging down the breed's lifespan and costing a lot of money for annual heart monitoring.

What are breeders doing about this intolerable situation?

  • Medical research is ongoing, but at this point responsible Cavalier breeders are waiting until at least age 3 or 4 before allowing any Cavalier to breed. The hope is that older dogs who haven't yet developed MVD might be contributing genes that are more resistant to it.
  • Responsible breeders will only breed a Cavalier whose own parents made it to at least 5 years old without developing MVD.
  • Finally, responsible breeders are maintaining registries of the longest-lived Cavaliers in the hopes of incorporating these lines into their pedigrees.

What should really be done is to begin a serious crossbreeding program to introduce healthy heart genes into the Cavalier's gene pool. But this wise solution is always shot down by short-sighted breeders (usually dog show enthusiasts) who think it's more important to keep a sick breed "pure".

Neurological diseases in the Cavalier King Charles Spaniel

As if the heart disease wasn't enough, epilepsy is also a serious problem in Cavaliers. Epilepsy in dogs can be tricky to manage.

Now let's talk about syringomyelia in the Cavalier King Charles Spaniel.

The most recent disease to strike this hard-luck breed is syringomyelia (seer-IN-go my-EEL-ya).

Syringomyelia begins when a Cavalier pup is born without enough room in the back of his skull for his brain to fit. This is called a Chiari-like (kee-AR-ee) malformation.

The vast majority of Cavaliers were born with this Chiari-like malformation.

This too-crowded space forces the brain backwards, down into a channel that interferes with the free flow of cerebrospinal fluid (CSF) between the brain and the spinal cord. This interference results in a variable fluid pressure that can hollow out a little cavity called a syrinx in the spinal cord.

In about half of those Cavaliers with a Chiari-like malformation of the skull, the abnormal pressure is mild enough that no syrinx forms. Those lucky dogs have no symptoms.

In the less fortunate 50%, a syrinx forms (sometimes more than one), and then you'll see symptoms, which typically appear between 6 months and 3 years old, though sometimes later.

The most common symptom is an odd one – the dog suddenly raises a high foot and scratches at his shoulder when excited or when walking on a leash. This scratching is presumed to be due to abnormal skin sensations – we presume this because humans with syringomyelia describe the sensation as "creepy crawy burning pain."

So it's not a funny symptom – the dog is experiencing discomfort.

Affected dogs may also be sensitive around their head, neck, and front legs, and may suddenly yelp when you're grooming them, or even for no apparent reason.

Pain may be related to head posture – some affected dogs begin sleeping with their head propped up on something like a pillow.

Dogs with syringomyelia often have petit mal seizures.

The most severe cases have actual spinal cord damage and are significantly disabled by 12 months of age, with a twisted neck, wobbly hindquarters, and/or weakness in their front legs.

There's no cure for syringomyelia. Mild cases can lead relatively normal lives, with the goal being to reduce the abnormal skin sensations that cause scratching and the pain that causes yelping.

The mainstay medications for syringomyelia are gabapentin to mute the abnormal skin sensations, lasix and omeprazole to reduce fluid build-up in the brain, and occasionally prednisone to relieve inflammation. Acupuncture can help. Surgery can relieve symptoms temporarily, but seldom provides a lasting cure. Severe cases progressively deteriorate and need to be put to sleep.

Orthopedic diseases in the Cavalier

Now let's turn our attention to the joints (knees and hips). The Orthopedic Foundation of America evaluated the hip X-rays of 7700 Cavaliers and found 13% dysplastic. That's high for a small breed.

Luxating patella (loose knee joints) is quite common, as well.

Eye diseases in the Cavalier King Charles Spaniel

Serious eye diseases in Cavaliers include cataracts, retinal dysplasia, eyelash abnormalities, dry eye, corneal ulcers, and progressive retinal atrophy (PRA).

Allergies and ear infections in the Cavalier

Allergies cause itchy skin and can lead to bacterial skin infections ( pyoderma). Ear infections are common due to profuse hair in the ear canal.

Other health problems in the Cavalier

Other health issues that occur in Cavaliers include diabetes, hypothyroidism, blood-clotting disease (thrombocytopenia), inherited hernias, and inherited deafness.

It's hard to find anything positive to say about Cavalier health, but one mild condition that occurs in the breed is "hanging tongue," where the tongue protrudes through the front teeth or hangs out the side of the mouth. This may be a structural defect or a neurological defect, but it isn't really anything to worry about.

Preventing health problems

Some health problems are inherited. For example, if your dog inherits from his parents the genes for an eye disease called PRA, he will go blind and there's nothing anyone can do about it.
