Sentry Understands Anxious Pets

Sentry uses pheromone technology to effectively change your pet’s behavior. With the help of their products, good behavior is right around the corner.

Change the Behavior, Not the Pet

Pets can’t talk, so they show they’re scared, frustrated, or not feeling well by changing their behavior. Give them the help they need for excessive barking or meowing, jumping on guests, licking, scratching, and spraying with the Sentry line of behavior products.

About Sentry

Sentry pheromone technology helps promote balanced behavior with science-backed solutions. Help your pet stay cool, calm, and collected with Sentry Behavior.

Questions & Answers

What does the noise sound like? Is it detectable to humans?

Answer by Chewy • Dec 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 Chewy • Jun 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 Chewy • Feb 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.

Perfect for Training

My dog would bark every morning when I was getting out of bed. Just using Sentry twice, stopped the barking.

If you drop this canister, the sprayer will NOT go back on, and is useless. As far as getting the barking dogs attention, yes, it does that, but the can does not last long at all.

If I am understanding correctly, this is supposed to disrupt a dog doing an unwanted behavior through both sound and smell (pheromones). We tried it today and yesterday when my dog, Benji was doing some attention barking. He heard the sound, but continued on. We’ve also used “Pet Corrector” in the blue bottle from another brand, and that one worked just as well (only sound mechanism no pheromones). If you use the spray repeatedly in a few seconds, the can will get very cold. For this price, I would try Pet Corrector first. That has worked occasionally for me and my dog. I’d be interested in trying this again with another dog, because this seemed ineffectual.

Not good

The spray hiss got our pup’s attention at first but he soon got so he ignored it. The container didn’t hold many bursts either; it was soon empty.
