A Wyoming boy heroically used his own body to shield his sister from a 2020 dog attack. A year after the vicious ordeal, he thinks he could have done more to protect his younger sibling.

Bridger Walker did not think twice about jumping in front of a big German Shepherd. The 7-year-old Cheyenne resident needed 90 stitches on his face after the terrifying dog was finished with him.

“If someone had to die, I thought it should be me,” he said according to People Magazine.

Celebrities and people from around the world have sent Bridger presents and fan letters since aunt Nikki first shared Briger’s horrific experience on social media.

Some of the many Hollywood greetings came from Chris Evans from Captain America, Mark Ruffalo (The Hulk), and Brie Larson (Captain Marvel).

“I truly respect and admire your courage,” Ruffalo said according to USA TODAY.

“Pal, you are a [real-life] hero,” Evans said in a video shared on Instagram. “What you did was so brave, so selfless, [and] your sister is so lucky to have you as a big brother.”

“Keep being the man you are, we need people like you … [and,] based on what I have seen, I do not think there is much that can slow you down,” he added.

All of this international attention has not changed the young man’s outlook even a year later. He continues to be very modest about his actions.

“It almost bothers him sometimes when he is called a hero because he [thinks], ‘Maybe I could have done more to shield her,'” father Robert said according to People Magazine.

Briger’s touching story of self-sacrifice also inspired different health specialists to offer the child different treatments for free, or a very minimal fee.

“He gave us so much hope,” the father said according to the New York Post. “That was kind of our first rainbow after all of this.”

New York dermatologist Dhaval Bhanusali treated the boy’s scars on a pro bono basis. This helped the child avoid a lengthy two-year wait for another specialist.

Bhanusali was pleased to report his patient “took it like a champion.”

“I probably showed more pain in my face doing it than he did,” he said according to People Magazine. “That kid is the bravest little dude I have ever met in my life. I do not think people quite understood the level of injury it really was.”

Robert enjoys seeing his “brilliant” little boy gradually return to his usual “fun, gregarious and full-of-life” self.

The father also expressed gratitude to everyone who showed so much love and assistance during what has been a difficult 12 months.

“It was absolutely miraculous,” he said. “For thousands–if not millions–of people to reach out from around the world, to a stranger that they have never met because they are concerned about the wellbeing of a 6-year-old boy in the middle of Wyoming … there is something special there.”

“I could not be more grateful,” he added.
