Noncardiogenic edema in dogs is a medical condition where the blood vessels of the lungs become more permeable, meaning fluid can pass through the blood vessel walls and leak more easily. Fluid then leaks into the lungs and causes swelling. In turn, dogs may experience an inflammatory reaction.

The condition can result from issues including an obstruction in the airway, trauma to the head, and injuries arising from biting an electric cord. If not treated quickly enough, it can also become fatal.

If you see signs that your dog is suffering from unusual symptoms or swelling, then you must consult your veterinarian for a proper diagnosis and advice. Here’s what you should know about the symptoms, causes, and treatments of noncardiogenic edema in dogs.

The cause of noncardiogenic edema in dogs can be due to a number of incidents and situations. Some of the most common causes include:

  • Obstructions of the upper airways (including injuries from choke chains)
  • Trauma to the head
  • Aspiration pneumonia
  • Bacterial infections
  • Inhaling smoke
  • Injury from biting through an electrical cord
  • Inflamed pancreas

Veterinary Treatments

If you worry that your dog is suffering from noncardiogenic edema, then your veterinarian will want to ask about your dog’s recent activities and any incidents that might have brought on the condition.

They’ll also carry out a full physical examination, including blood work and tests to see how effectively your dog’s blood clots, plus pulse oximetry ratings. Imaging techniques might also help your vet confirm a diagnosis.

Treatment will depend on the severity of the condition. In extreme cases where a dog is having breathing issues, a period of further hospitalization will likely be required. Vets use oxygen therapy in many cases, and they may also consider the use of a respirator.

In general, vets often suggest a spell of crate rest, along with minimizing any environmental issues that could stoke a dog’s anxiety.

While the prognosis for dogs who become severely ill is not good, dogs who only experience mild to moderate symptoms often make a full recovery.
