Signs of Heart Failure in Dogs: What Every Pet Owner Should Know

Heart failure in dogs isn't a minor issue—it reflects serious problems when the heart can't pump enough blood to meet the body's needs. This guide covers critical dog heart failure symptoms, from sudden distress to slow decline, so you can catch early signs of heart failure in dogs and act wisely.

Acute Heart Failure in Dogs

• Labored breathing: Rapid, exaggerated chest movements indicating distress.

• Weak, irregular pulse: A "fast but faint" heartbeat.

• Lethargy or collapse: Unable to stand, wants to lie down.

• Pale or bluish gums: Low oxygen due to poor circulation.

• Bulging veins: Neck or outer veins may swell visibly.

• Tremors or seizures: May collapse and lose bladder control.

• Foamy discharge: Sign of pulmonary edema.

Chronic Heart Failure Signs

• Reduced activity: Gets tired after light walks.

• Color change in gums/eye lining: Bluish-purple due to low oxygen.

• Swollen veins: Especially on legs or neck.

• Peripheral edema: Swelling in legs; leaves indent when pressed.

• Heart murmurs or arrhythmias: Detected via veterinary auscultation.

What to Do for Dog Heart Failure Treatment

If your dog shows acute symptoms, immediate oxygen support is critical. Vets often prescribe:

• Diuretics to reduce fluid around the lungs.

• ACE inhibitors (e.g., enalapril) to ease blood pressure.

• Positive inotropes like pimobendan to boost heart pumping.

• Sometimes antiarrhythmic drugs (e.g., amiodarone) for rhythm issues.

Long-term care should include a low-sodium, high-quality diet, gentle exercise, and regular vet check-ups to track progression and adjust treatment.
