Originally styled after a 1950 Mercury, and later a custom body, the truck has a canine motif, complete with big ears, tail and tongue.

In 2016, the entire fleet of floppy eared fidos all received facelifts due to the update of the classic Mercury body style, now featuring three-dimensional teeth and real studded collars.

A fourth truck, Monster Mutt Junkyard Dog, made its debut, but would be retired in April of the same year.

For 2019 Cynthia Gauthier is going to compete in the Stadium Series 1 representing the Fire and Ice Version of the Monster Mutt Dalmatian.

It was piloted for a few years by Charles Benns (the rottweiler monster truck's original driver) and is now driven by former Team Grave Digger superstar Rod Schmidt.

Unlike its predecessors, the truck retains the classic Mercury body that Monster Mutt was so famous for, this time with a rusty design.
