Borophagus gives its name to the entire borophagine subfamily within Canidae, which includes some of the smallest known canids, but also the very largest, Epicyon, which has been estimated at 170 kg or so! No wild canid before or after is known to have reached this size.

Epicyon haydeni.

Though the measurements aren’t based on any particular specimens the mounted skeleton at the museum of Los Angles is a great reference.

A very powerful canid shape.

Not good with children, other pets, will absolutely destroy your entire house
