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.

Got this to help train my kitten to stay off counters. This seemed to only work through fear of the noise the canister makes. Positive reinforcement with treat and clicker and changing the surface of the counters has worked way better. The smell it produced was very strong and irritating and actually bothered me. It also ran out in 2 days. Not worth it.

Dog couldn’t care less!

My dog isn’t bothered by the spray sound at all and the smell is awful and way too strong! Irritating! Not a fan. Can’t recommend it.

Cat hates it, I love it!

Skippy is horrible when it comes to sitting in front of the TV meowing! All I have to do is show her the Sentry bottle and she stops the bad behavior!

Very effective.

Makes an impact. Should only be used to stop big time “No, no’s”. Not for correcting little things.

The sound of the spray.

I think the sound scared the kitties enough for them to stop their wrong doing. :)

I sprayed it maybe two times. Now I don't even need to spray it. Just get it and pop the top and my cat immediately stops the bad behavior. He now doesn't do his usual bad behavior habits he used to do every night. So highly recommend
