Here's how it works:
1. The Scoop: The dog curls its tongue into a cup shape and dips it into the water.
2. The Lift: It quickly flicks its tongue upwards, bringing a mouthful of water with it.
3. The Swallow: The water is then swallowed.
This lapping method is much more efficient than trying to suck water through a straw, which is how humans drink. Dogs have evolved this specialized technique for several reasons:
* Efficient: Lapping allows dogs to quickly and easily ingest large quantities of water.
* Adaptable: They can drink from various sources, including puddles, streams, and bowls.
* Less Messy: Lapping prevents them from spilling water all over themselves.
So, next time you see a dog drinking, remember that they're not actually drinking *through* their tongue, but rather using it as a clever tool to scoop up water!
