Sound Defense dog deterrent is your go-to protection against aggressive canines. Using patented technology to deter aggressive dogs the Sound Defense sends an audible signal into the sensitive hearing range of dogs, coyotes, and wolves triggering the flight response. Instead of chemical irritants and dog pepper spray, with the simple press of a button, repel dogs from up to 25 feet to intimidate and turn away aggressive animals.


Your Sound Defense warning device offers a dog pepper spray alternative that does not use any chemical irritant or propellants, saving you from harmful blowback and any need to buy and replace expensive chemical cartridges. Instead, each device comes with a 9-volt battery and allows for easy air travel. With each button press between 2 to 15 seconds, you’ll have more than 1 whole hour of continuous use for maximum protection. No pepper spray means no blowback in your eyes.


No need to have perfect aim. Just hold the button, and the audible sonic dog repeller defender broadcasts its sound over a wide, effective field. That’s up to 25 feet of safe zone between you and any aggressive hound foolish enough to think about approaching you.
