TL;DR: Pink frothy discharge from a dog's nose or mouth is a life-threatening medical emergency indicating fluid in the lungs. Transport your pet to an emergency veterinarian immediately for oxygen therapy and life-saving care.
What does it mean if my dog has pink frothy discharge from their nose or mouth?
- This is often a sign of pulmonary edema, which occurs when fluid leaks into the air sacs of the lungs.
- The frothiness is caused by the fluid mixing with air as your dog breathes.
- The pink color indicates that a small amount of blood has mixed in with that fluid.
Is pink frothy discharge a medical emergency?
- This is a life-threatening medical emergency that requires immediate intervention.
- Froth at the nose indicates your dog is struggling to breathe and is not getting enough oxygen.
- Potential causes include congestive heart failure, trauma, toxin exposure, or near-drowning.
- Stop reading and transport your dog to the nearest 24-hour emergency veterinary hospital immediately.
How does taking a photo of the discharge help the triage team?
- If you can safely take a quick photo of the discharge or a video of your dog's breathing without delaying your trip, please do so.
- Seeing the consistency and color helps the triage team immediately determine the severity of the lung congestion.
- This allows the hospital to prepare oxygen therapy and life-saving medications before you even walk through the door.
Clinical Context (Merck Veterinary Manual)
Sneezing accompanied by nasal discharge can be indicative of acute rhinitis, characterized by respiratory stertor, open-mouth breathing, and/or inspiratory dyspnea. The nasal discharge is initially serous, progressing to mucoid with secondary bacterial infection, and potentially mucopurulent with inflammatory cell infiltration. Furthermore, the presence of pink frothy liquid should raise suspicion for cardiogenic pulmonary edema, especially in small-breed dogs with chronic valvular disease, requiring radiographic evaluation for definitive diagnosis. Further diagnostics such as rhinoscopy and nasal flushing may be needed.
