A Puppy Mosh is a gathering — held at contests, weekends or club nights — in which Pups play together in a designated area while Handlers supervise, tend to gear and provide care. Moshes are commonly playful and non-sexual in character, focused on interaction between Pups, exercise of headspace and community.

Puppy Moshes became a signature event of Puppy Play community life as the tradition matured, appearing regularly at leather runs and dedicated conferences.

Rules vary between events. Most Moshes emphasise consent, supervision by Handlers or a designated monitor and respect for the shared space.
