There's a reason that dogs are truly a man's best friend, and that is their undying loyalty to their 2-legged companions.

Dogs are known for their unconditional love towards us humans, and it's pretty safe to say that we often give that love right back.

From the smallest gesture to putting their lives on the line, you hear some pretty incredible stories about dogs having their humans backs. Keep scrolling to find out about the two most loyal pooches...

They aren't called "man's best friend" for nothing...

Dogs are some of the most loyal and trustworthy animals that we humans can come by. With pups being one of the most popular pets across the world, it's clear that we all tend to share a mutual love of the fluffy little guys.

We will do anything to protect our faithful companions...

There's nothing quite as horrifying as the thought of something happening to our beloved dogs, and we often find ourselves going to extreme lengths to protect our furry little friends.

Remember the guy who punched a kangaroo for his dog?

Yep, that's right, one man actually punched a huge kangaroo that had gotten his beloved dog into a ferocious headlock. Luckily, nobody was hurt and the kangaroo hopped away with a slightly bruised ego.

Now that was an extreme case...

But we will often do whatever it takes to protect our pooches, including running out into traffic when our dogs have escaped or even breaking up a fight between your dog and the neighbors' - often resulting in some pretty nasty cuts and bruises.

But what about when our dogs look out for us?

Dogs are used all around the world in emergency services to help people in need, such as fire-rescue dogs who are there to help to sniff out people stranded in burning buildings or in the aftermath of rubble and ruins.

But pet dogs have been known to step in with a helping hand, too...

Especially when it comes to children, dogs are known to be protective and will put their lives on the line in order to protect "their human."

Back in 2007, a Doberman-Pinscher saved the life of a seventeen-month-old baby from a venomous snake by pushing the child out of the way and taking the snake bite himself.

Luckily, he was injected with anti-venom and lived to tell the tale of his life-saving actions.

A woman's life was saved when her very own dog stopped her from choking...

She began choking on an apple when her Golden Retriever jumped up and down on her chest until the apple was dislodged and flew out according to the American Society for the Prevention of Cruelty to Animals, who awarded the dog with a commendable mention.

But even when they're not saving lives, they're still always by your side.

And he is also autistic and can't speak.

The only comfort that the family had whilst Marshal was missing, was that the two family dogs had gone with him.

After reporting his disappearance to the police, the family, neighbors and local authorities spent several hours searching.

Marshal was eventually found by a neighbor just a mile away from his home.

Marshal aunt, Kayla Stewart also spoke to WJHG and said, "We were panicked. All sorts of worst case scenarios are running through their heads."

Corey Dobridnia, the Public Information Officer at the Walton County Sheriff’s Office, told Bored Panda, "Minutes are precious when it comes to the search of a child."

He also added, "Marshal was in good spirits when found. A little dirty from the walk through the woods, but unharmed and happy,"

"Dogs are loyal creatures. I feel like they probably knew to stay with him when they saw he was alone. Their instincts kicked in. They stayed with the boy and watched over him until he was located." When Marshal was found the Facebook post was updated with a comment that said, "We don't deserve dogs'.

Dogs really are man's best friends!
