When it's not hot, the dog sticks out his tongue to breathe (what's wrong with the dog's mouth always open)

When it's not hot, there may be several reasons why dogs stick out their tongues and gasp:

1. Dogs will stick out their tongues when they are thirsty after playing for a while.

2. Dogs want to be accompanied by their owners and stick out their tongues when coquetry.

3. The characteristics of dogs' illness, such as respiratory diseases.

If the dog breathes with its tongue out for a long time when the temperature is right and it is not thirsty, it is suggested that you take the dog to the hospital for a general examination and treatment as soon as possible.
