Great product
My mom's crazy barking dog has had shock collars ( worked O.K. limited) had collars that make noices and hanging things (no results) has had the debarking surgery twice within a month( not so great for the $250.00 dollars and seems a bit cruel. My mom has given this spray collar a 5 star award and wished we had tried it first, especially before the surgery which she really didn't want to do and felt bad about.Try this first before anything else but I suggest that you don't let the sprayer run out. Some dogs are very smart and might catch on.
