Wagner Lima, a 34-year-old Paraguayan cowboy, passed away on New Year’s Day 2017 in a motorcycle accident in Brazil. Everyone who knew Wagner knew how much his dear horse Sereno meant to him, and vice versa.

Wagner and Sereno were the very best of friends for many years.

Wagner’s brother Wando instantly knew that Sereno should be at the funeral, alongside his human friends and closest family members.

“This horse was everything to him,” Wando said. “It was as if the horse knew what was happening and wanted to say goodbye.”

Wando led an emotional and powerful march to his brother’s final resting place in the city of Cajazeiras, Brazil. Sereno marched with them, but no one in the crowd expected just how the grieving horse would react when he got close enough to Wagner’s casket to pinpoint Wagner’s scent.

Wando says he will now be taking care of sweet Sereno in his brother’s honor.
