Answer: positive


Question: I was skeptical that this would work to keep my hound dog quiet - but it works like a charm! Maybe because her nose is more sensitive?? We don't always put her bark collar on, but when we let her out at night when her barking would be more disturbing to neighbors, it works as described. Sometimes we only put the collar on and not activate it - that also works now that she associated the spray with the collar.

Answer: positive
