Recognizing the Signs of Congestive Heart Failure in Dogs: Symptoms and What to Watch For

Understanding Congestive Heart Failure in Dogs

Congestive heart failure (CHF) in dogs occurs when the heart cannot pump blood effectively, leading to fluid accumulation in the lungs, abdomen, or limbs. This condition can result from various underlying heart diseases and is most common in older dogs.​

Early Signs of CHF in Dogs

Early detection of CHF can significantly improve management and quality of life. Watch for these initial symptoms:​

• Persistent Coughing: Especially after exercise or at night.

• Difficulty Breathing: Rapid or labored breathing, even at rest.

• Exercise Intolerance: Tiring quickly during walks or play.

• Lethargy: Reduced energy levels and increased sleep.

• Pacing at Night: Difficulty settling down before bedtime.​

These signs may be subtle but warrant a veterinary evaluation to rule out heart issues.

Advanced Symptoms of CHF in Dogs

As CHF progresses, symptoms become more pronounced:​

• Increased Respiratory Rate: Even while resting.

• Bluish Gums or Tongue: Indicating poor oxygenation.

• Swollen Abdomen: Due to fluid buildup (ascites).

• Fainting or Collapse: Often triggered by exertion.

• Loss of Appetite: Reluctance to eat or drink.

• Weight Loss: Muscle wasting and overall weight reduction.​

These symptoms suggest significant heart compromise and require immediate veterinary attention.

When to Seek Veterinary Care

If your dog exhibits any of the above signs, consult your veterinarian promptly. Early intervention can slow disease progression and enhance comfort.
