Manufacturer ACME understands like no other to produce dog whistles in absolutely identical pitch even over decades.
Therefore quite clearly our recommendation from own experience with the hunt dog training: Decide with your first dog for this universal dog whistle set and buy immediately a supply of the identical dog whistles on stock for your cars, different jackets and your family members.
Plus, stick with the once-chosen dog whistle model for years to come! Your dog will always know that HE is meant.
