Do dogs clean their mouths every 7 seconds?

That's a common myth, but it's not true. Dogs don't clean their mouths every 7 seconds.

While dogs do lick their lips and nose frequently, it's not a constant action that happens every 7 seconds. It's more about:

* Grooming: Licking helps clean their fur and remove debris.

* Cooling: Panting and licking help dogs regulate their body temperature.

* Sensory exploration: Licking is a way for dogs to explore their environment and gather information.

So, while dogs do lick often, it's not a specific, timed behavior.
