Sadly, dogs can be unpredictable animals.

However lovable they may seem, when they aren't treated well from being a puppy or trained in the correct way, a dog can be aggressive and, ultimately, very dangerous.

Neglected dogs tend to be the most unsociable...

And they can cause an unbelievable amount of damage to us humans - especially to children.

Dogs have even been known to cause death in the past...

So when raising children around dogs, it's super important to be cautious at all times.

But when one family experienced an aggressive stray dog...

A 6-year-old boy showed the most incredible act of kindness by putting himself in harm's way to protect his little sister.

Nikki Walker, who is from Cheyenne, Wyoming, took to social media to tell her nephew's heroic story last year.

6-year-old Bridger was playing with his sister recently when disaster struck.

What was assumed to be a stray dog came charging over to the children...

And, without thinking, Bridger pushed his little sister out of the way and took the full force of the dog himself.

Writing on Instagram, Nikki said:

"He, himself, took on the attack so that the dog wouldn’t get his sister. He later said, 'If someone was going to die, I thought it should be me'."

The 6-year-old was immediately taken to the hospital once the dog lost interest...

And even though he was soon discharged, he was left with some serious facial injuries. But thankfully, this story has a happy ending.

Nikki explained:

"After getting bit several times on the face and head, he grabbed his sister's hand and ran with her to keep her safe. After receiving ninety stitches (give or take) from a skilled plastic surgeon, he's finally resting at home. We love our brave boy."

Nikki wants her nephew's story to be shared...

"Please, share my nephew’s story so that it gets as much exposure as it can. We know that our little hero would love some words of encouragement from his favorite heroes," she wrote, alongside tagging the likes of Tom Holland, Chris Hemsworth, Robert Downey Jr., Mark Ruffalo, and Chris Pratt.

Bridger's story has since been shared thousands of times...

And the little boy has been receiving flurries of praise from all around the world.

People have been left touched by Bridger's selfless actions...

And the fact he was willing to risk his own life for his sister is truly heartwarming.

It's rare to see acts as selfless as this...

And Bridger's parents have been condemned for doing such a great job in raising their children.

But this story also demonstrates how dangerous dogs really can be...

And Bridger was actually very lucky to walk away without any long-lasting injuries.

Now, we have a health update from the little boy's dad, who posted some progress shots of his injuries...

Of course, people were thankful to see that the scarring had decreased dramatically.

We're so glad the scars are healing!
