How does it work? Every time your dog barks, the electronic bark-sensing unit releases a painless spray of citronella in front of the dog's snout. Your dog hears it, sees it, feels it, and smells it!
Most of us are familiar with its pleasant lemony scent. Citronella is an essential oil that is derived from the stem and leaves of lemon grass and has been used in medicine for a thousand years.
The original 3rd generation model includes:

Citronella spray refill or scentless refill
Aboistop, a self-sufficient product, requires no human intervention; it will work even if you are not there. Should you want to reverse the effects of Aboistop, just stop using the device. Ultimately, the animal can be trained to cease barking without having to wear the device. Aboistop is the only humane solution to the problem of nuisance barking.
