What happens when a Samoyed sneezes?

An occasional Samoyed sneeze is normal, just like in humans, from irritation by smells, dust, or hair, so no need to worry. But if it sneezes often with lethargy, cough, or runny nose, it likely has a cold; give pet cold and anti-inflammatory medicine promptly.

If there is no improvement after 2-3 days of medication, take it to a vet to check for viral infection or lower respiratory infection.
