Did you know that the tiny vertical groove between a dog’s nose and upper lip actually has a purpose? It’s called the vegetal groove (or philtrum), and it’s not there by accident!
Each time a dog licks its lips, a bit of saliva collects in that groove. Through a process called capillarization, the moisture travels up to the nose — helping keep it damp.
And why does that matter? Because a moist nose is much better at capturing and holding scents from the air. 🌬️✨ That’s part of what makes a dog’s sense of smell so incredibly powerful!
Nature’s design is always so clever, isn’t it? 🐕💛
