Here's why your canine companion is actually pretty smart

Did you know that dogs can detect things like seizures, low blood sugar and cancer? A new AsapScience video looks at some of the scientific wonders of man's best friend.

They might technically have the knowledge of a 2-year-old human, but dogs are actually pretty smart. A new video from AsapScience explores the ins and outs of the science of man's best friend.

Of all the animals out there, dogs are actually pretty similar to humans. When you are laughing or crying, for example, dogs react to your emotions just like other humans would -- they get sad when you're sad, and happy when you're happy.

Dogs can have a beneficial impact on your romantic life as well. Studies have shown that men are three times more likely to get a girl's phone number if they have a dog along with them, according to the video published Sunday. So you could meet your future partner just by taking your dog out for a daily walk.

Have you ever wondered why dogs curl up when they're resting or sleeping? Aside from it being more comfortable, lying like this protects your pooch's vital organs in their stomach from predators like coyotes, mountain lions and, as it goes in my house, toddlers.

Watch the video below to learn even more about our canine companions, like how dogs aren't actually completely colorblind, and that they can sniff out medical conditions like seizures, low blood sugar and even cancer.
