7 Early Signs of Heart Disease in Dogs & How to Protect Their Heart
Heart disease can silently affect your furry friend — often without obvious signs until it’s too late.
Maybe your dog’s been coughing at night or seems tired after short walks.
You might notice them struggling to breathe or acting a little dizzy sometimes.
It’s natural to worry when your furry friend shows these signs — you just want to keep them safe.
Many dog owners feel the same and wonder when to take action.
That’s why recognizing the early signs of heart disease is crucial.
In this article, we’ll walk you through 7 common symptoms to watch for — empowering you to take action before it’s too late.
1. Persistent Coughing
Does your dog cough often, especially at night? This could be a warning sign of heart problems.
If the cough worsens or includes phlegm, it’s time to visit your vet.
2. Getting Tired Easily After Exercise
If your dog seems exhausted after walks or playtime — more than usual — this might indicate heart issues.
3. Difficulty Breathing or Rapid Breaths
Labored or fast breathing that happens frequently is a red flag for heart disease.
4. Fainting or Dizziness
Irregular heartbeats can reduce oxygen flow, causing your dog to faint or feel dizzy.
5. Swollen Belly or Weight Gain
Fluid buildup in the abdomen, known as ascites, can cause swelling and signals worsening heart function.
6. Pale or Bluish Gums and Tongue
Changes in gum or tongue color can point to poor blood circulation related to heart disease.
7. Irregular Heartbeat
Notice if your dog’s heart beats too fast, too slow, or unevenly — this needs veterinary attention.
