Trisable Silent Dog Whistle is FREE and is a silent dog whistle application that includes two 'dog hear-able' frequencies that can be used to attract a dogs attention. This dog whistle application uses two high-frequency sound files that are started and stopped with the use of finger-friendly buttons.

Dog whistle sounds or dog trainer whistle sounds are difficult for a human to hear but fully audible to our canine friends due to their greater hearing range.

Please enjoy this free dog whistle application courtesy of Trisable software.
