This collar is lightweight and comfortable for all sizes of dogs.

The collar detects the sound of the dog barking and administers a short spray of citronella to distract the dog. In time, this acts as a deterrent and the barking will reduce or stop altogether.

It is effective for 30-40 sprays per refill. It is supplied complete with an 88ml citronella scented refill can.

Additional refill cans are available. 

This item uses a PetSafe 6V alkaline battery (included).
