Amazing siblings! Check out the full story below.
The boy's mom posted the pictures and video on to Facebook with the caption: "Look at my puppy's reaction to the beautiful tribute, his face tattooed inside a lion's mouth. The video is EXCITING. That's why I saw Rafa asking Erick to make brave face."
She later added: "My dear friends, when I posted this video I could swear that it would not cause this dimension of sharing that caused. THIS IS CALLED GOD. Because he was the cause of the success of this video, because contrary to what many people think, I have never had anything easy in this life, only US and GOD and the closest friends know well what I've already spent in life so Erick is here with us."
