This is the heartbreaking moment a pet horse was overcome with grief as his late owner and ''best friend'' was buried.
Cow herder Wagner Figueiredo de Lima, 34, and 8-year-old grey stallion Sereno were ''inseparable'' and spent up to 12 hours a day together.
The Paraguayan cowboy struck up an ''incredible bond'' with the beast, which he had owned since birth, as they grazed cattle on the remote farm land.
But Wagner was killed in a motorcycle crash in the early hours of the morning on January 1 in Rio Grande do Norte, Brazil, near his home in neighbouring state Paraiba.
