It worked, on the big woofer and the little happen. Didn't hurt them, just gave them a surprise and they stopped in mid bark. Now we are all ready to go camping and I won't have to worry about the other campers.

Once set up this collar is very effective and being small and light weight it is suitable for small dogs.

Dog collar worked well. Dog stopped barking after 3 days

Bought Ultrasonic Bark Stop Control Barking Dog Collar - seemed to be working until dog got it off and between the 3 dogs we have it got destroyed..........

We have the bark stop for our small dog to assist with training whilst out on walks. The sensor appears to active with normal activity and it is unclonclusive that it reduces his barking whilst on a walk. Mind you, the product manual does say intended use is for nuisance barking for a dog at home, that is sedentary.

Great service and delivery...but product turns on sometimes and sometimes doesn't. Bit frustrating. Bit of a shame.

got it and fits great ty
