Wang was 11 years old when her mother gave her a white Samoyed that she named Reno.
That dog grew up with her, slept by her side, and accompanied her for more than a decade. When Wang learned she was pregnant, Reno died. Months later, her son was born with a mark on his left arm, exactly where the dog had a mark on its paw.
The doctors who examined the baby were clear: it was simply a birthmark, with no medical significance. But to Wang, this coincidence was not accidental. Since then, she believes Reno is still by her side, now on her son’s skin. The story, which originated on social media, continues to divide those who read it between science and faith.
