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

We've used this three times since I bought it and seems to help. While they are not outwardly calm, the destruction is a great deal less! It went from torn pillows and blankets to their toys strewn about. Overall I would say this was a good purchase.

We’ve been using this product for a couple weeks and it seems to be helping some. Our youngest is marking less and all 3 of our babies seem like maybe they’re a little more relaxed. We are hopeful and plan to keep using it for now.

My dog has severe separation anxiety any time I walk away from her , like it’s ridiculous. I bought the calming collar , spray and wall diffuser and I haven’t noticed any difference. :(. We have also tried cbd and that doesn’t work either. Not this companies fault per se , my dog is just very needy !

Didn’t diffuse

I had the same problem as a few other people, it never diffused any oil. Of course I noticed after an autoship refill was already sent.

I have been using the Sentry calming spray which works amazing for my pup with separation anxiety. I purchased the diffuser hoping it would provide relief throughout the day for him but it has not. I will continue using the spray instead. Save your money and don’t buy this product.

I've tried everything over the last 5-6 years to help keep our rescue dog calmer. And I do mean everything. I ran across this product and decided to give it a try. Much like everything else we've tried, it does nothing unfortunately. It smells good when you're right up on it but otherwise I can't smell anything.
