15 Things Your Dog Can Smell That You Can't.
If you ever felt like your dog has a sixth sense about things, it's because they do. Well, sort of. It´s not so much of a sixth sense, but a highly enhanced 5th sense. We're talking about their sense of smell. It's so powerful, that it puts a human's sense of smell to shame. They can detect all sorts of things. They can even distinguish the smallest changes in scents, which can alert them to threats that we're totally clueless about. That's how awesome dogs are. So, if you're feeling a bit intimidated by your pooch's sense of smell, you should be.
While humans rely on all their senses, the sense of sight is their favorite, but dogs are different.
Dogs have the same five senses we have, but they navigate the world around them using mainly their sense of smell. So, next time they're sticking their head out of the window, it may not just be to get some fresh air.
Dogs have two olfactory bulbs connected to the brains that decodes all sorts of different scents.
Each bulb weights 60 grams, which is four times heavier than our own olfactory bulbs. It´s also more efficient, since this gives dogs 4000% more scent receptors than we have. So, it's no wonder we put their sense of smell to good use.
Dogs are very astute, and thanks to their sense of smell, they can tell when you're coming home.
Haven't you ever noticed how your dog is always there waiting for you at the door? It's not that they've been sitting or standing there all day for you to come back from work. They can recognize the scent of your car engine as it pulls into the driveway, which essentially tells them you're coming home.
Dogs don't rely on their eyes to recognize you or someone else in the family that they love.
They use their sense of smell to remember who you are. Even perfume and colognes can't hinder their ability to sense that it's you. It's why they're so welcoming to you, but growl when a stranger is nearby.
Dogs have been used by security officials at airport, subways, and other terminals to detect danger.
With training, they're able to sniff through packages and determine whether something being brought over on a plane or a train is harmless, or contains potential deadly chemical explosives, or bio hazardous material.
