My puppy had two vaccines, still has nasal congestion and runny nose for 7 to 8 days, appetite and energy good, wormed and tested negative for distemper. Is it a cold?

A puppy’s nasal congestion and runny nose may be from a cold or from an upper respiratory infection secondary to the earlier cough. Keep the puppy warm promptly and give it honeysuckle tablets and canine doxycycline, and let it drink more warm water to clear inflammation. If yellow nasal discharge persists without relief, use antibiotics and anti-runny-nose medicine via nebulization to moisten and open the airways.

For a long course, check at a hospital for sinusitis, pneumonia, or bronchitis. If the runny nose is accompanied by severe cough, lethargy, poor appetite, or fever, consider distemper infection..
