You know that mess next to your dog’s water bowl?
You may clean it up, but researchers actually studied what causes it.
The problem is that dogs can’t suck. So how do they drink?
Scientists studied a dog’s tongue with a waterproof camera placed at the bottom of its bowl.
They discovered that dogs curl their tongues backwards and plunge them into the water.
The water sticks to the back of the tongue and makes a column, which the dog bites off.
As for cats, who also don’t suck, they tend to be much gentler drinkers, barely touching their tongue on the liquid’s surface, as opposed to dogs who plunge right in.
