We occasionally use the citronella collars for our pups and they work great. We only use them when someone new is coming to visit or workmen are around the house. That sort of thing sets them barking and keeps them upset. The collars seem to tell them that we have approved the visitors and they don't need to alert us - haha. We have three small dogs but do not use the collar on one since she has some breathing problems anyway and we don't want to aggrevate those. They really do not like the smell of the citronella.
