5 Common heart disease symptoms in dogs

We all know how big dogs hearts are - they are affectionate and love unconditionally! But sadly, like humans, dogs can be diagnosed with heart disease which can make them very sick or worse. 

Heart disease is used to describe a number of conditions that affect the heart’s natural functions. Most heart conditions in dogs involve a decrease in how effectively the heart can pump blood which can lead to a build-up of fluid in the chest or abdomen.

If your dog exhibits any of the common symptoms of heart disease, it’s important to contact your vet straight away as the sooner heart disease is diagnosed, the sooner the vet can put your dog on a care plan to help manage it.

Here are the 5 most common signs of heart disease in dogs. 

Coughing or hacking

This is usually a persistent cough that is intensified after exercise, at night or even after eating. Coughing can be caused by an enlarged heart or a fluid build-up in the lungs because the heart isn’t pumping efficiently. Any cough that lasts more than 5 days should be investigated by a vet.

Fainting or collapse

When the heart cannot function correctly, vital organs struggle to receive nutrients - especially oxygen to the brain which can lead to fainting or collapse. These can be brought on by strenuous exercise or after a coughing fit.

Fatigue

Dogs with heart disease will become lethargic and may not be able to exert themselves in the same way they used to. They may sleep or rest more than usual.

Difficulty breathing

Dogs with heart disease may breathe more heavily or quickly because they are struggling to breathe. Some dogs may try and increase their oxygen intake by stretching their neck out and standing with their legs wide apart. Keep an eye on these unusual movements and call your vet as soon as you notice your dog struggling to breathe.

Behaviour change

Your dog’s personality might change. Dogs that once were very active or playful might seem quiet or withdrawn. Dogs that once loved food might stop eating as much. Behaviour changes are often a sign that something is wrong with your dog’s health, so don’t hesitate to contact us if you see a change.

What increases my dog’s risk of heart disease?

There are a few factors that could increase your dog’s risk of heart disease which include their:

• Age - Heart conditions in dogs occur more frequently with increasing age.

• Body condition - Overweight dogs are more likely to develop heart disease.

• Breed - In dogs, chronic valvular disease is more common in small breeds such as cavalier king Charles, spaniels, miniature poodles, cocker spaniels, Pomeranians and schnauzers. Myocardial disease is more common in large and giant breeds like Great Danes and Irish wolfhounds.

Can heart disease in dogs be treated?

Although treatments cannot reverse heart disease, your dog can live a relatively normal life if seen by a vet. Some treatments could include a new diet, daily medication or surgical intervention depending on the severity.
The most important thing is to get your dog checked by a vet as soon as you notice any of the above symptoms so they can diagnose it quickly and start a treatment plan to allow your dog to live a happy, comfortable life.
