Yesterday I was flipping through the Foster & Smith catalog and I saw that they have these no bark collars that spray the dogs with this lemon spray whenever they bark. I was wondering if anyone has experience with this. It seems a bit startling and I wonder if the lemon stuff hurts the eyes. I have no intention of buying this thing but was curious to know if anyone out there has used one of these. Nikko is a yapper but this seems a bit to drastic for him.
