Mitral valve disease (MVD) is a degenerative heart condition most commonly seen in middle-aged to older small-breed dogs. It involves the progressive thickening and dysfunction of valves within the heart, eventually leading to heart disease symptoms in some dogs.

Whilst this sounds pretty scary, the good news is that our vets can offer lots in the way of screening, monitoring and support of pets affected by MVD to help extend their lifespan and maintain their quality of life.

1. Screening pets for MVD

Many cases of MVD in pets are first discovered during routine health checks by the detection of a heart murmur (an unusual heart sound). For this reason, we recommend health checks every six-to-12 months in all dogs eight years old and above, particularly for at-risk breeds such as cavalier king charles spaniels.

2. Monitoring pets for heart disease

If a murmur suggestive of MVD has been detected, we will discuss various monitoring options based on that pet’s particular condition. These include:

• Monitoring the pet’s sleeping breathing rate – an increase above 30 breaths per minute when they’re deeply asleep (and not dreaming!) warrants a prompt veterinary recheck
• Chest x-rays to measure the size of the pet’s heart and look for any signs of fluid accumulation in or around their lungs
• Monitoring the pet for any symptoms of heart disease, such as becoming puffed with exercise
• For some pets, referral for heart ultrasound (echocardiography)

3. Treating pets for symptoms of heart disease

If pets with MVD proceed to a more advanced stage of heart disease, our vets will discuss medical options to reduce their symptoms and improve their quality of life.

Whilst we sadly can’t cure pets of heart disease, we can help protect your heart and theirs by maximising the quality and quantity of time you spend together.
