Heroes come in different shapes and sizes and there is one such hero that is being celebrated worldwide for saving his sister from a dog attack.

He grabbed his sister and ran away from the spot. 

The incident gave Bridger 90 stitches. His aunt shared his story on social media. 

The six-year-old told his family that if one amongst the siblings was supposed to be dead, he thought it should be him. 

Bridger's bravery is making headlines across the world. The Instagram post has garnered over a million likes, with fans including Captain Marvel and Captain America.

"I hope I am hald as brave in my life as you are in yours," she said.
