Vale Veterinary Group | Cullompton, UK

When it comes to keeping your dog happy and healthy, a strong heart is key.
At Vale Veterinary Group, we understand how worrying it can be to hear that your dog may have heart disease. The good news is that with early diagnosis plus the right care and support, many dogs go on to live full and joyful lives.

Let’s walk through what heart disease in dogs really means, how to spot the early signs, and how our team—and veterinary cardiologists when needed—can help.

Contact our friendly team today if you have any concerns about your dog’s heart health.

What Does Heart Disease Look Like in Dogs?

“Heart disease” isn’t one single condition—it’s a term for different problems that affect how well the heart pumps blood. Some dogs are born with it, others develop it over time.

Common Types of Canine Heart Disease:

  • Mitral Valve Disease (MVD):
    A leaky heart valve makes it harder for blood to flow the right way. Very common in smaller breeds like Cavalier King Charles Spaniels.
     Learn more about Mitral Valve Disease here.
  • Dilated Cardiomyopathy (DCM):
    Mostly seen in larger breeds like Dobermans and Great Danes. The heart muscle stretches and weakens, making it less effective.
  • Heartworm Disease:
    Caused by parasitic worms that damage the heart and lungs if left untreated. This is rare in the UK, but quite common in the US and Canada.
  • Pulmonary Hypertension:
    High blood pressure in the lungs that makes the heart work overtime.

Why Do Dogs Get Heart Disease?

Some factors are out of your control, while others can be managed with healthy habits:

  • Breed and Genetics: Some breeds are more prone to heart problems.
    Check breed-specific risks.
  • Age: Just like people, a dog’s heart can wear out a bit over time.
  • Lifestyle Factors: Poor diet, dental disease, lack of exercise, and obesity can put extra strain on the heart.

How Can You Spot Heart Trouble Early?

Often, dogs hide signs of illness surprisingly well. That’s why it’s important to trust your instincts if something feels “off.”

Common Signs of Heart Disease:

  • Persistent coughing, especially at night
  • Getting tired easily or slowing down on walks
  • Difficulty breathing, or breathing faster than usual
  • Loss of appetite or noticeable weight loss
  • Swollen belly (caused by fluid buildup)
  • Sudden collapse or fainting episodes

Behaviour changes can be a clue too, like if your dog seems anxious, restless, or doesn’t want to play like they used to. Here are some more signs to watch for.

How We Diagnose Heart Disease

At Vale Veterinary Group, we combine hands-on care with modern diagnostics to get answers quickly.

First Steps:

  • A careful physical exam: listening to the heart and lungs
  • Checking pulse, breathing, and gum colour

Diagnostic Tools We May Use:

  • X-rays: To look at the heart’s size and shape
  • Echocardiogram (heart ultrasound): To see how the heart is functioning in real-time
  • Electrocardiogram (ECG): To check for abnormal rhythms
  • Blood tests: To check overall health, and to look for infections

Sometimes, when cases are complex, we work closely with veterinary cardiologists. These heart specialists use advanced imaging and testing to fine-tune a diagnosis and create tailored treatment plans.

How We Treat Heart Disease in Dogs

Treatment really depends on the exact problem, but our goal is always the same:
To keep your dog feeling as good as possible, for as long as possible.

Common Treatments:

  • Medications: Like diuretics (to remove extra fluid), blood pressure medications, or drugs like Pimobendan to help the heart pump better
  • Lifestyle Changes: A special diet, keeping a healthy weight, and sensible exercise
  • Advanced Care: Some dogs need pacemakers, heartworm treatment, or even surgery if valve damage is severe

When needed, we can refer you to trusted veterinary cardiologists who offer advanced treatments such as valve repair or minimally invasive procedures.

Can Heart Disease Be Prevented?

Not always—but there’s plenty you can do to protect your dog’s heart health:

  • Bring your dog for regular vet checks, especially if they’re older or a breed at risk
    Learn about preventive care for seniors.
  • Keep them at a healthy weight with the right food and exercise
  • Ask us about early screening tests if your dog is at risk based on their breed

When to Seek Immediate Help

Call us right away if your dog:

  • Struggles to breathe
  • Faints or collapses
