Questions & Answers

20 Customer Questions

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.

Hi, is this product allowed on an airplane? I will be traveling with my dog soon, and was wondering if it was FAA Approved.

Worked for the first few times

I was very excited the first time I used this, it stopped my puppy in her tracks. After about the third time ( over a few days) it didn’t phase her, and actually she lunged toward it in my hand.

The product I used was labelled: Sentry STOP THAT! Behavior Correction for dogs & cats (1 oz) Worthless! A few short walks and only maybe 10-20 attempts to use and its empty. The hiss begins as soon as you press, but the spray is delayed too long. This occurs even when the can is held perfectly upright; if the can is slightly tilted it's even worse. I would NEVER buy or recommend this product.

It helps

Seems to help when my dog gets over excited when she sees other dogs, Still trying it out. Be sure to press the plunger all the way down, a good firm push.

It does work, however, for the price, the container doesn't last very a dog takes longer than a week! This is a short term item....

Good for Limited Use

Used with my fur babies to help with a barking issue. It worked as a surprise noise element, but only for a very limited time.

very effective

This worked better than anything I have tried before to stop excessive barking. After a few times, all I have to do is pick up the container. I like that I don't have to spray it now but I know I can if I need to provide a reminder.

Worked the first time

Maybe it's our puppy is more curious than others but it only worked the first time on him then it stopped.

Comforting spray

This did not help at all, not even a little. It actually irritated on dog and more aggressive

Stop That spray

Chewy does a great job getting the products delivered in a reasonable time as well as great selections. This product is expensive and does not work well. As well it’s a very small can with very little in it.
