What does the noise sound like? Is it detectable to humans?
Answer by ChewyDec 04, 2019
For a demonstration, please click on the available video. The sound is audible to humans and other pets in the area.

If this is completely safe, why the label warning for pets and children?
Answer by ChewyJun 14, 2018
The Sentry Stop That! Noise & Pheromone Dog Spray is non-toxic and can be used around pets and children. The warning is to ensure the product is used properly.

Does this help dogs not fight with their Siblings
Answer by ChewyFeb 03, 2018
The spray’s pheromone mist redirects the pet’s attention and behavior. The effect is longer lasting than noise alone and helps the pet not to re-engage in the negative behavior.

Crazy barking

I was unsure if this would really work, I have two sm dogs that bark at any sound from outside. Used this the first time and it’s not a loud sound, caught their attention right away and they stopped barking and laid down. Was so surprised. Normally they don’t stop when tolded to. I’ve used a few times in the first week and I have 90% less barking. . Highly recommend this product it worked for us.

Buy this product

I bought two and I don’t think that I’m ever going to need to open the second one. I have two large Rottweiler puppies and I’m at the point that I just need to show them the spray can and their bad behavior STOPS. When I take the cap off their behavior IMMEDIATELY STOPS. No more jumping, bullying, going into the fireplace, chewing what they shouldn’t, just bad behavior period. I carry it around on my person like a gun in a holster, not that I even own a gun, LOL. WOW. GOOD JOB.

Really impressive

My puppy responded immediately to the sound and maybe the smell of this product. I've been trying to get her to stop jumping on friends and neighbors for months with moderate success. This product seems to have done the trick, I'm really impressed with its effectiveness.

Bark stopper

Works on older dog to stop barking. Most of the time when I take the top off and shake the can she stops. I have a young dog who gets too rough herding the older dog. This spray/sound stops her behavior.

Finally found something that works

I have tried so many products to help keep my dogs from barking at people who walk in front of my home. This product has helped quite a bit. It has not solved the problem but we are finally making progress.

a pump sprayer this aerosol to loud !

Why not a pump sprayer - the sound the aerosol spray very loud - when walking - very difficult. Made a bad noise and dog under stress from dog behind fence. He slipped his harness ( never did before)

I was extremely surprised at how well this worked. I actually bought it in 2020 and still have it for when my 2 year old pup needs a correction but just seeing the can he behaves. When we first got it we were having issues with him being a bigger bread and nipping and not knowing when his play was getting too aggressive, and wanted to stop it immediately and this was a life saver!

It Works surprisingly well.

I have tried everything for Sir Barks Alot, my very vocal pup. Collars, calming aids, handheld ultrasound things, nothing works for more than a day or two. I blasted my dog with this amazing gift of silence and it worked. I’m almost out so I will be ordering more, but actually all I need to do is show him the can and he shuts up. I’ve even blasted it out the door when he’s outside and it works. Now I just show him the can and he quiets down, I believe that can speaks his language.

Sentry "Stop That" Pheromone Dog Spray

Love this product. Works great with my dogs. I have 4 and sometimes they'll get into a fight over toys, food, etc. When you spray it makes a loud noise that gets their attention. Then when they get a whiff of the pheromone, they all just lay down and chill out. Now, all I have to do is show them the bottle and they calm down.

not happy with the results

I had bought this a couple of years ago and it was good. This one had a very strong smell that lingered for a while, made my husband sick. It did not stop her from barking
