6 Warning Signs of Heart Disease in Pets

Heart disease in pets is more common than you might think, and early detection can make a significant difference in treatment outcomes. As pet parents, it’s essential to recognize the warning signs and seek veterinary care if you notice any of the following symptoms.

1. Dry Cough After Exercise
A persistent, dry cough—especially after exercise or while sleeping—may indicate fluid buildup in the lungs, a common sign of congestive heart failure.

2. Excessive Tiredness or Fainting
If your pet seems lethargic, reluctant to play, or even faints, their heart may be struggling to pump enough oxygen-rich blood throughout their body.

3. Difficulty Breathing
Heavy breathing, shortness of breath, or rapid panting—especially when at rest—can signal heart disease. Pets with heart conditions often develop labored breathing as their heart becomes less efficient.

4. Swollen Abdomen
An enlarged or swollen belly may be caused by fluid retention, a symptom linked to advanced heart disease. If your pet’s stomach appears bloated or firm, consult a veterinarian immediately.

5. Rapid Weight Loss
Unexplained weight loss can be a red flag for various health issues, including heart disease. Pets with heart failure may experience muscle wasting despite maintaining a normal appetite.

6. Pale or Bluish Gums
Check your pet’s gums—healthy gums should be pink. Pale or blue-tinged gums suggest poor circulation and a lack of oxygen in the bloodstream, which can indicate a serious heart condition.

When to See a Veterinarian
If your pet is showing any of these signs, it’s crucial to schedule a veterinary exam as soon as possible. Early diagnosis and treatment can improve your pet’s quality of life and prevent complications.
