Auto Citronella Bark Collar Waterproof IPX67 Spray Bark Collar with 3 Adjustable Spray & Sensitivity Level, Rechargeable Citronella Dog Collar Humane Anti Barking Collar for Dogs

Our dog has a 9 inch neck and we've tightened as far as it will go. It moves so we have to reposition it. Despite that it's worked very well. After 2 weeks he whispers instead of barks. He will bark at door knocks so hoping that gets better. It beeps then sprays at which time we say "no bark" then praise him when he's been quiet for a bit. Helps him understand. Battery life is very good. I charged it adter a week. I don't think there's any vibration. Very good quality.

I purchased this product in October, around the 20th. The spray didn’t generally come out at a high-pitched bar, but after about two months, the device no longer works. The spray mechanism doesn’t accept the compressed gas from the canister. Its fizzes out.

So I was having trouble with my neighbors as my dog was barking all the time. I got this collar yesterday and started using it immediately. My dog sort of freaked out when the collar sprayed her the first two times. But now if she starts barking I only have to hold up the collar and she stops. She does not want me to put it on her. Smart puppy.

I like that it was easy to set up and the instructions were clear. It also comes in a structured box with all the necessary components.

This product has decreased my terrier's barking by 85-90%! In a small home this is a major benefit! The only reason I did not give it 5 stars is the unit does not automatically show a constant red light when the collar needs recharging or refilling.
