People may shrug away a runny nose but to your dog, who has 220 million smell receptors compared to your 5 million, it can be a big deal. And while nose discharge can be a sign of something as simple as your dog's excitement that you're home, it can also be a symptom of a problem as serious as cancer.
Generally, you don't have to worry about clear nose discharge in dogs unless it lingers or there are other symptoms.If there's a clear nasal discharge from your dog's nose, chances are good it's caused by allergies, by far the most common reason for abnormal nasal secretions in dogs. However, discharge that's cloudy, yellow, green, or smelly is always cause for concern. When in doubt, talk to your vet.A discharge from just one of your dog's nostrils is often a sign there's something stuck in that nostril, like a seed or blade of grass. Other signs include sneezing, pawing at the nose, and nosebleeds.If you can easily see what's in your dog's nose, carefully remove it with tweezers. If you can't, call your vet, who may need to sedate your pet to dislodge the blockage, and then prescribe antibiotics to avoid infection.
A nose discharge of mucus or pus could indicate your dog has a bacterial, fungal, or viral infection. Additional signs of an infection might include a bad odor, a nosebleed, and coughing or choking resulting from postnasal drip.Treatment depends on the cause. For a bacterial infection your vet may prescribe several weeks of antibiotics. Fungal infections usually require special treatments using topical anti-fungal drugs. Surgery may be necessary if your dog has chronic infections.
Blood, pus, or mucus can be a sign that your dog has nasal polyps (overgrown mucus-producing glands) or nasal tumors. Other signs include noisy breathing or a bulge on one side of the nose.
