Dogs are such amazing and fascinating creatures! Love them so much!!!! ❤️
Did you know that the tiny vertical groove between a dog’s nose and upper lip isn’t just a random detail? It’s actually called the philtrum — or sometimes the vegetal groove — and it serves a fascinating purpose!
Each time a dog licks its lips, a bit of saliva collects in that groove. Thanks to capillarization, that moisture travels up to the nose, helping keep it damp. And here’s why that matters: a moist nose is far better at capturing scent particles from the air. 🌬️✨
That little groove plays a big role in what makes a dog’s sense of smell so extraordinary. Nature really thought of everything, didn’t it? 🐶💛
