Have you ever noticed your dog's nose running? Just like humans, dogs can experience nasal discharge, which can range from clear and watery to thick and purulent. It's essential to pay attention to the appearance and frequency of this discharge as it can provide valuable insights into your dog's health. In this article, we'll dig into the causes of dog runny noses and when you should be concerned.
Could My Dog Have Allergies? In Short, Yes.
If your dog has a thin, watery discharge without any color or odor, it's likely a sign of mild irritation in the nasal cavities. This can occur due to seasonal allergies or inflammation caused by an inhaled foreign object like grass or seeds. In some cases, antihistamines may help clear up the discharge without further incident. Dogs can respond to environmental allergens just like humans, with symptoms such as red, watery eyes, sneezing, and a runny nose.
More Serious Causes of Dog Runny Noses
If the nasal discharge is thick, has an odor, or shows discoloration with blood or pus, more serious causes are suspected. In such cases, it's crucial to consult your veterinarian for a thorough investigation. Your vet will consider your dog's recent history, including any exposure to kennels, grooming, dog parks, or daycare facilities. They will also review your dog's vaccination status to ensure they are up to date.
After the initial history and examination, your veterinarian will discuss potential causes of your dog's runny nose. If both nostrils are involved, the causes are usually different than if only one nostril is affected. Both nostrils may indicate a generalized cause, while a single nostril points to a localized source. If the discharge is clear, thin, and watery, your vet may recommend antihistamines and monitoring at home. In some cases, a small amount of discharge may be normal, and no further treatment is needed.
However, if the discharge continues or worsens, further diagnostics are required. In the case of unilateral discharge (one nostril involved), possible causes may include an inhaled foreign body like grass or grass awns leading to rhinitis, a fungal infection, or a nasal tumor. Your veterinarian may start with a course of antibiotics. If there is no response, a rhinoscopy procedure may be necessary. This involves anesthetizing your dog, inserting a camera into the nostril to examine the area, and taking samples for culture and biopsy. In some instances, a CT scan of the head may be needed to make a definitive diagnosis.
When both nostrils are involved, it suggests a more generalized problem like a viral or bacterial infection. Dogs are susceptible to both, especially if they frequent kennels, dog parks, or grooming facilities. Canine influenza is becoming more common and often presents with a runny nose, fever, sneezing, coughing, lethargy, and a lack of appetite. Pneumonia can also be a possible complication. Additionally, canine kennel cough, a common bacterial complex, can cause nasal discharge when it progresses to pneumonia.
