The Physics of Drinking Dogs

We have now firm confirmation that dogs and cats drink alike!

Earlier on, there was a study on the mechanics of cats drinking water. It turns out that in a new study of dogs drinking water using high speed camera and x-ray images, dogs drink the same way as well!

This footage shows that as the tongue touches the surface of the water, the liquid adheres to it, creating a water column as the tongue is drawn back towards the mouth. The dog then snaps its mouth closed just as the water begins to fall backwards towards the bowl.

The research, published in the journal Biology Letters, has surprised scientists because it reveals that cats and dogs drink in the same way.

I'll post the exact citation to the paper when I find it.
