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.
