Ingredient Information

Instructions

Balance. Support. Promote

For over a decade, Sentry has worked with leading pet experts and top universities, researching effective ways to help pets lead happier, less stressful lives.

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.

It Works!

I've had a terrible time potty training my dog. Then thought it would be worth trying the calming diffuser and she no longer potty's inside when I'm gone.

Works very well.

This really calmed my cats and dogs. Some can be for dogs or cats or both. It has a nice, good smelling scent. Makes the pet calm and relaxed. I feel it lasted more than 30 days but just follow the instructions. They also have other products like a collar and sprays. Smells really good. I used it for my cats and dogs. As young as a 2 yr+ to senior age. A bit pricey but so worth it.

Waste of money

I have 11 dogs and with them being stuck in the house for winter, things are a little tense. I thought this would help. Not at all. Waste of money

I wasn’t sure if this was working, but then when my dog was getting really antsy and wouldn’t settle down easily, I realized that the diffuser had been empty for several days. Additionally, his vet recommended it, and I truly feel there is a benefit for him. Even if it doesn’t help him - the small fragrance that it gives off is pleasant enough for me to keep it on autoship!

I plug this in when we're camping in our RV. Both dogs sleep soundly through the night, without needing to go outside to the bathroom. They get me up at home and that's bad enough, but making noise during the night in a campground would be bad for everyone. I was happy that I could save a few bucks and get the refill, rather than replace the whole unit--which lasts a long time, by the way.
