They work well

My dog ​always barks often, and neighbors often complain. I tried to buy this product, the effect is amazing. My dog ​​never barked frantically again, which reduced me a lot of trouble.

It's great. It's easy to do. I wish this could be a little bit smaller.Thinner is even better.

The effect is good, with a few operations is really dare not shout, really God, after not afraid of being complained about, trustworthy

This product is really amazing,my dog likes inexplicable barking,later tried this product,only used twice before stopped barking,the effect is really incredible.Sincerely recommend!

I've just bought a dog that barks all the time, so I've chosen this dog trainer to give me a buzzing warning that my dog is more obedient and no longer barks
