Yup... Part of the reason their sense of smell is so acute... 300 million olfactory receptors and a third of the brain devoted to deciphering scene probably plays a big part too 😉 and shows us just how critical small is in their thinking process...
Dogs trust their nose first, then their ears (hearing 30x greater than ours), then their eyes in order of sensory perception feedback... God was so serious about canine scent perception he even invented the Jacobson's organ, a secondary olfactory system in the roof of their mouth (that pea sized lump behind their upper front teeth). This one is more devoted to detecting pheromones used in communication, tracking prey and understanding social cues. Humans even have one, but unfortunately ours is more of a non functioning vestigial organ at this point 🙁
Dogs truly are the ultimate scent detectors. Scent rules their lives...
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? 🐕💛
