[EX Q]: 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.
[EX A]: positive

[EX Q]: If you’re thinking of starting, have started or even have been eating Keto, this book is a must have! This is exactly what I was looking for when I started!
[EX A]: positive

[EX Q]: Great color, but it doesn’t fit my 38mm series 1 properly on one side. It would be a 5-Star product if both sides stayed on properly. Disappointment otherwise.
[EX A]:
negative
