Hercules - Reception and Administration

Hercules is a 7-year-old Coton de Tulear who loves meeting old and new friends at the Melbourne Musical Theatre Studio. Born in 2019, he is proud to be the first Coton born in Victoria.

Upon your arrival you can expect a warm greeting from Hercules. He loves a scratch under his chin or on his butt, but he doesn't like being patted on top of his head. Once your lesson commences, he will settle down and patiently observe, keeping an eye on the clock, and ensuring your lesson runs smoothly.

When not maintaining professional standards at the studio, Hercules loves to get outside on a sniffari, or going on an adventure in search of the perfect wide-open space for zoomies.
