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

Would this help my really hyper dog calm down around people ?

Answer by Chewy • Aug 30, 2018
This calming collar helps alleviate problem behaviors caused by stressful situations such as travel, thunderstorms, new pets in the home, new visitors, car rides, and vet visits.

Do the calming effects eventually wear off after continued use? Do they become immune to it?

Answer by Chewy • Mar 25, 2024
When using Sentry calming products, the perception of the pheromones by pets is immediate. However, as in every behavior program, the visible improvement in specific behaviors requires some time, depending on a variety of factors including: the animal, the nature, duration and severity of the problem, and behavior modification.

Will this collar stop my dog from chewing up everything

Answer by Chewy • Jan 23, 2022

Is it safe for puppies

Answer by Chewy • Sep 17, 2020

These aren't a miracle cure, but they seem to take the edge off our dog's anxiety. He was having trouble settling down in a new house after our move, and following us around anxiously. Within half an hour of putting this collar on he finally went to bed on his own and stopped following at our heels. He was still anxious, but at least able to rest a little. I think these are a decent add-on to whatever else you might be doing to reduce anxiety. I have found they work better than another brand and also better than the pheromone sprays.

I think it’s working!

Hard to tell but I think it’s helping our girls with thunder storms! It’s expensive so we only put on just before storms and take turn off once they calm down.

Material

It does not meet my expectations. He does not respond to this version of the calming collar. Others (the black one) was more effective.
