I have used Citronella collars to great effect to stop unwanted barking. Worn like a normal collar, they have a microphone to pick up the sound of the bark and this triggers a puff of citronella into the face of the dog, which dogs don’t particularly like, but which doesn’t harm them. Charge up the Citronella Collar with the fragrance, switch the battery to ON and wait for the bark.
Here’s what happens …
Woof – pffft … (confused look)
Little woof – pffft …. (look of recognition)
…. no more woof!
The expression on the dog’s face is priceless!
