Why do people say: dogs sneeze, but it will be sunny? Thank you, everyone.

A dog's nose secretes a liquid to maintain a good sense of smell and other functions. So the dog's nose is wet. When the weather is dry, it will accelerate the evaporation of this secretion, leading to dry nose, nasal irritation and sneezing. Dry weather will naturally clear up. Personally, I think, ha, there is no research, but when you come back and invite me to eat tenderloin, I will consider helping you with your research.
