Aspiration pneumonia affects dogs when they breathe in anything unfamiliar, such as food, vomit, or saliva, causing their lungs to swell up. Here, we look at how this condition can be sorted out.

In dogs, aspiration pneumonia is a condition when the lungs swell up after inhaling anything foreign, like food, vomit, or saliva. These chemicals have the potential to infect the lower respiratory tract and result in pneumonia when inhaled. 

This article will explore canine aspiration pneumonia causes, symptoms, treatment, and prevention strategies.


Aspiration pneumonia in canines causes include:


  • Vomiting and regurgitation: Dogs who often vomit or regurgitate are more likely to develop aspiration pneumonia, particularly if the vomit enters the lungs rather than being ejected.

  • Anesthesia: Dogs are frequently intubated and put under anesthesia during surgical operations. If the dog throws up or if the tube isn't placed correctly, the danger of aspiration may rise.

  • Swallowing disorders: Dogs with problems like megaesophagus, where the esophagus does not work as it should, are more likely to regurgitate, which increases their risk of aspiration pneumonia.

  • Neurological conditions: Brain abnormalities and myasthenia gravis are two neurological diseases that can make swallowing difficult and raise the risk of aspiration pneumonia.

Aspiration Pneumonia in Dogs Symptoms

Dog aspiration pneumonia can present with various symptoms, depending on the infection's severity and the underlying cause. 

  • Coughing

  • Difficulty breathing or rapid breathing.

  • Fever

  • Lack of appetite

  • Weakness and sluggishness

  • In severe cases, the skin or gums may have a bluish color

  • Discharge from the nose


It's crucial to seek veterinarian assistance immediately if you think your dog may have aspiration pneumonia. Ways of diagnosing by a vet include:

  • Physical examination

  • Using a stethoscope to listen to the lungs

  • Chest X-rays: X-rays can be used to identify lung anomalies and establish the existence of pneumonia.

  • Blood tests: Bloodwork can reveal the existence of an illness and assess the dog's general health.

  • Tracheal wash or bronchoscopy: Both bronchoscopy and tracheal washing require taking samples from the airways to pinpoint the precise bacteria or organisms responsible for the infection.

Aspiration Pneumonia Treatment for Dogs

Treatment for canine aspiration pneumonia typically involves supportive care and addressing the underlying cause. The veterinarian may recommend the following:

  • Stabilization and supportive care: Dogs with aspiration pneumonia may need to be stabilized very away, especially if they are in significant respiratory distress. This may involve the delivery of supplementary oxygen to help them breathe, intravenous fluids to keep the patient hydrated, and vital sign monitoring.

  • Antibiotics: Bacterial infections are frequently the cause of aspiration pneumonia. To treat the illness, broad-spectrum antibiotics are typically recommended. Antibiotics will be selected based on the exact bacteria implicated, which can be detected through diagnostic procedures such as a tracheal wash or bronchoscopy. It is critical to take the antibiotics exactly as directed and to finish the whole course of treatment.

  • Nebulization and chest physiotherapy: Nebulization treatment is giving medicine directly into the respiratory system using a nebulizer, which aids in opening the airways and reducing inflammation. Chest physiotherapy, such as moderate percussion or vibration, can also help loosen and remove mucus.

  • Cough suppressants: Dogs suffering from aspiration pneumonia may experience a chronic cough that causes discomfort and irritation. Cough suppressant drugs may be administered to relieve coughing and enhance respiratory tract recovery. Cough suppressants, however, should not be taken if the cough is productive (generating phlegm), because coughing helps clear the airways.

  • Nutritional support: Because of their pain, dogs suffering from aspiration pneumonia may have diminished appetite or difficulties eating. Your veterinarian may prescribe alternate feeding techniques, such as a feeding tube or syringe feeding, to ensure your dog receives appropriate nourishment and fluids throughout the recuperation time.

How to Prevent Aspiration Pneumonia in Dogs

It is critical to adopt preventative steps in dogs to limit the risk of aspiration pneumonia. These include:

  • To decrease stress and distractions, feed your dog in a calm and peaceful atmosphere.

  • Elevated food bowls or feeding platforms can help dogs with regurgitation or known swallowing issues like megaesophagus maintain normal eating posture.

  • Smaller, more frequent meals are preferable to larger, more frequent meals, which can lead to overeating and regurgitation.

  • Feeding your dog right before or after hard activity might also contribute to regurgitation.

  • If your dog eats rapidly, slow-feed bowls or puzzle feeders may help.

  • Supervision at mealtime: Keep an eye on your dog while he or she is eating to avoid overeating or ingesting strange things.

  • Anesthesia precautions: If your dog requires anesthesia, ensure the veterinary staff takes care to reduce the danger of aspiration.

  • Address underlying health issues: If your dog has a swallowing difficulty or any underlying illness, cooperate with your veterinarian to manage it properly.

  • Avoid feeding your dog improper items: Be mindful of what your dog has access to, both inside and outdoors, to avoid them eating foreign things that might cause choking or aspiration. Keep dangerous materials out of your dog's reach, such as tiny toys, bones, or other objects.

  • Environmental safety: Provide a safe environment for your dog by removing any dangers that might cause damage or aspiration. This includes securing electrical wires, keeping poisonous chemicals away from canines, and eliminating or controlling any possible choking risks.

  • Veterinary treatment: This is vital for monitoring your dog's overall health and detecting any underlying disorders that may contribute to aspiration pneumonia. Work together with your veterinarian to handle any existing health conditions, such as megaesophagus or neurological diseases, to reduce the chance of aspiration.
