Query: Dogs still bark

I have two dogs and they are not big barkers but every so often they have their moments. So I bought this item hoping it would alleviate the barking to some degree but it does not help at all. My son has even tried plugging it in right next to where the dog is barking and it has had no effect whatsoever. It is now back in the box so do not waste your money.
