The moment your dog barks a painless and harmless citronella spray is released towards their muzzle which surprises them.

The collar brings a corrective action based on different sensorial factors: the sight (the cloud of spray), the hearing (pschitt), the touch (cold contact) and the smell .

The effect of this surprise is sufficient to interrupt the dog's excessive barking. The dog will therefore associate the collar with the need to stop barking. In a few days the dog learns to keep quiet while wearing the collar so no more trouble with the neighbours!
