My dog only gets anxious when in a car. She doesn’t need it all of the time, but once you put it on you have to leave it on? It won’t last any longer if you take it off? It only lasts up to 4 weeks, so it gets pretty expensive!

Answer by Chewy • Sep 07, 2018
The calming collar is required to stay on for the full 4 week period. If removed consistently, the effect would wear-off.

Is this collar safe for a mixed dog/cat household?

Answer by Chewy • May 29, 2021
This collar is safe to use while around other pets.

What is this made out of? I have two large chewers and they tend to chew plastic on each other's collars.

Answer by Chewy • Dec 07, 2018
This collar is made out of silicone.

Is this a one-time use product or is it refillable?

Answer by Chewy • Nov 01, 2018
Each collar can be used up to 4 weeks.

Separation anxiety

Have been wrestling with separation anxiety whenever we have to be gone. (Cody lost his 2 companions last year due to age). I bought the Thunderease pheromone

Have been wrestling with separation anxiety whenever we have to be gone. (Cody lost his 2 companions last year due to age). I bought the Thunderease pheromone jars and put them around the main room...I noticed a slight change. Giving him 300 mg of Trazadone helped a bit more. The combo of the jars, the Trazadone and the collar did the trick and he hasn't caused any additional damage to the entry door.

I purchased two of these collars based on the reviews. One for an anxious senior to help him be more comfortable during car rides and the other for an over active yearling to see if it would help him focus. It was a waste of both time and money as there was no change in the behavior of either dog. Very disappointed.

We recently lost one dog to a tragic coyote accident. She was 11. Our other dog had been with her for that whole time and depression set in. We actually thought we’d lose him too. Our vet recommended this collar and it has been a lifesaver. It may not work for every pet but it definitely did for ours.

We really loved the diffuser version and thought to try this, but did not notice any improvement. I wish it could be put on and off more than once but seemed that once it was on, it had to be cut off and couldn't be reused which was unfortunate for bathing. Not worth the money but wish it had been!

I did notice a difference in my anxious dog. Unfortunately it fell off and it was lost. I have high hopes that the collar would be an effective way to help calm my dog for New Years Eve fireworks. I’ll be purchasing another one.

I use this for my dog with big feelings on leashed walks. He is less likely to explode with this collar. I know when it is wearing out because he is more anxious

My dog went from terrified to slightly worried during New Year’s Eve fireworks. This was the first time he didn’t hide under the bed, trembling. The collar and the spray were life changing for him.

Trying to help my 9 yr old Cavapoo, I bought this and put it on him, hoping it would help calm him down. He is a Velcro dog who also acts out anytime I am gone. The acting out involves finding any paper paper like products and shredding them. He has been wearing the collar and it was easy to use and adjust. However, I've seen absolutely no change in any of his behaviors. For him, it did not work.

It seemed to have no effect on her at all. She’s fine in the car until it moves and then she gets extremely nervous panting and running back and forth. I thought

It seemed to have no effect on her at all. She’s fine in the car until it moves and then she gets extremely nervous panting and running back and forth. I thought the collar would help but it didn’t so I’m trying to find another solution.

I have a very quirky dog who has a trauma history we'll never know fully. This collar makes a noticeable difference in her anxiety and reactivity. It also has no discernible smell, unlike other brands. We have it on autoship!
