I have used Citronella collars to great effect. They have a microphone to pick up the sound of the bark and this triggers a puff of citronella which dogs don’t particularly like, but which doesn’t harm them. I recently loaned one to our friend Nick at Urban Haze for a visiting dog who persistently barks at passers by. Charge up the Citronella Collar, switch the battery to ON and wait for the bark. Here’s what happened.
Woof – pffft … (confused look)
Little woof – pffft …. (look of recognition)
…. no more woof!
Smart dog! Early days yet but apparently the expression on her face was priceless!
