#2277: Chewhistle

Having a toy-oriented dog can be a nuisance when their favourite is a squeaky bone or ball.

Today’s invention is therefore a ball with a high-frequency whistle embedded.


As the canine in question gnashes on his rubber pal, air is driven through the whistle.

This generates sound at such a high frequency that only he (and the other neighbourhood mutts) can hear…thus maintaining some measure of domestic quietude.
