  • Oh dogs...A best friend that always has your back.

  • In fact, studies have shown that men are three times more likely to get a girl's phone number if they have a dog by their side.

  • And do you ever feel like your dog just gets you?

  • It turns out that humans and dogs both respond to emotional sounds.

  • When your dog hears you crying or laughing, the response in their brain is similar to that of a human's.

  • In fact, they interpret your crying as another dog whining, which may make you wanna cuddle your buddie.

  • But did you know that dogs often curl up into a ball when sleeping to conserve body heat and protect their most vulnerable organs in the abdomen from predators?

  • Comfy.

  • If you're not always around to cuddle, leaving them some clothes that smell like you will actually help them with separation anxiety.

  • And while you may think you have the smartest dog, animal psychologists believe most dogs are about as smart as a two-year-old human.

  • Dogs can understand more than 150 words, count up to five, and notice simple errors such as one plus one equals three.

  • Dogs are also capable of solving spatial problems.

  • They learn the location of hidden treats, find the fastest route to the park, and operate mechanism such as latches and simple machines.

  • And by the way, dogs aren't completely color-blind as many people think.

  • But unlike the three specialized receptors in our eyes to distinguish colors, dogs only have two.

  • Because of this, they see black, white, blue and yellow.

  • Meanwhile, their brains don't interpret red and green, but instead see gray.

  • Of the 75 million domesticated dogs in America, Labradors are the most popular.

  • But the most intelligent dog breeds are Border Collies, Poodles, and German Shepherds.

  • However, these are measures of intelligence that compare to our own.

  • Dogs are amazingly smart in other ways.

  • You've probably heard of drug sniffing dogs, but did you know that dogs can sense seizures, detect low blood sugar, and can sniff out cancer?

  • In one study, dogs were able to identify 30 out of 33 cases of prostate cancer by smelling participants' urine.

  • It's believed that dogs' highly sophisticated sense of smell can detect variation and the presence of volatile organic compounds.

  • Their sense of smell is 10000 to 10 million times more sensitive than humans', depending on the breed.

  • A secreted fluid from their nose helps them smell by capturing scent chemicals in a thin layer of wet mucus on their nose.

  • In fact, for a dog, breathing is different than smelling.

  • A small fold of tissue called the Alar Fold separates the flow of air, depending on whether they are sniffing or breathing,

  • which also allows them to pick up pheromones in the air to help locate and determine the readiness of possible mates.

  • Tinder for dogs.

  • On top of it all, humans really do love dogs.

  • A recent study found that dogs activate the same hormonal response that triggers us to love and care for our own babies.

  • Accompany that with studies showing decreased stress and anxiety, and it's clear why they've become such an important part of our lives.

  • They truly are women and men's best friend.

  • Umm well, unless you are a cat lover.

  • In which case, you should watch our scientific debate on cats versus dogs, where we try and figure out which precious pet is truly the best.

  • Head on over to that video to help us to decide which side wins, and subscribe from our weekly science videos.
