Symptoms of PDA Occlusion in Dogs

Recognizing the symptoms of PDA occlusion in dogs is crucial for early diagnosis and timely intervention. In this blog, our vets in Boulder will discuss the common signs that may indicate your furry friend is suffering from PDA occlusion.

Symptoms of PDA Occlusion in Dogs

When a dog has a small PDA defect, the symptoms may not be apparent initially. However, as the PDA grows, more blood flows through it, resulting in more noticeable symptoms. These symptoms may include:

Weakness and fatigue: One of the initial symptoms of PDA occlusion in dogs is excess weakness and fatigue. Your dog may appear lethargic, less interested in physical activities, and tire more easily than usual. This is often due to reduced oxygen supply to the body, leading to decreased energy levels. 

Rapid breathing and panting: Dogs with PDA occlusion may exhibit rapid and labored breathing, even when at rest. You might notice increased panting, which can result from the heart's struggle to pump blood efficiently. Keep an eye on your pet's breathing rate, as it can be a valuable indicator.

Coughing: Persistent coughing is another common sign of PDA occlusion in dogs. The cough can be dry or accompanied by the production of frothy, pink-tinged sputum. This coughing is often linked to the fluid buildup in the lungs caused by the heart's inability to pump blood effectively. 

Reduced appetite and weight loss: PDA occlusion can affect a dog's appetite, reducing interest in food and, consequently, weight loss. The weakened blood circulation may impact the digestive system, making mealtime less appealing for your furry friend. 

Blue or pale gum and tongue: In severe cases of DA occlusion, dogs can develop cyanosis, which is characterized by blue or pale gums and tongue. This discoloration occurs due to the inadequate oxygenation of the blood. If you notice these symptoms, seek immediate veterinary attention. 

Increase heart rate: An elevated heart rate, also known as tachycardia, can be a sign of PDA occlusion. Your veterinarian will be able to detect this through a physical examination. In some cases, a heart murmur may also present.

Fainting episodes: Advances PDA occlusion cal read to fainting episodes in dogs. These episodes, also known as syncope, occur when the brain doesn't receive enough oxygen due to compromised blood flow. Fainting can be a frightening experience for both you and your pet.
