They drink water differently than cats
As you already know, dogs and cats use their tongues to drink water, but dogs use “a simple lapping process with the tongue curled slightly backward to form a ‘spoon’ that collects as much water as possible and quickly puts it back into their mouth,” Reiter says.
When drinking water, cats use their tip of the tongue and keep it curled backwards so that the top of the tongue touches the liquid first.
