ACME 575 Professional Dog Training Whistle – In-Mouth, 100 dBA, UK Made

ACME 575: In-Mouth Training Whistle for Shepherds and Working Dogs

Rooted in decades of field craft, the ACME 575 offers a precise, audible signal when training or guiding dogs in open spaces. The in-mouth design relies on wind pressure and mouth shape to create a controlled tone, delivering a sound that can cut through wind and distance without being harsh or overwhelming.
