ACME Dog Whistle #210.5

A dog’s hearing range is far greater than that of ours; it is also far more sensitive to high-frequency sounds. ACME dog whistles are designed to produce the greatest response from your dog, even over exceptional distances. The 210.5 is ideally suited to Spaniels with a single frequency of 5900Hz. It is the best whistle for close work and for dogs who suffer from hard of hearing.
