About This Item

Details

  • This collar mimics the pheromone given off by nursing mother dogs to help comfort your pup.
  • It’s a long-lasting way to help keep your furbaby’s anxiety at bay.
  • Your pup just has to wear the collar to experience its calming effects, and it can even be worn with antiparasitic collars (sold separately).
  • Reducing your furbaby’s stress may help improve your relationship with your best friend.
  • This longer-lasting collar means there’s less need for replacements, so it’s an eco-friendly choice.

Is it recommended to use the collar along with the diffuser? Or do you use one or the other?

This collar mimics the pheromone given off by nursing mother dogs to help comfort your dog and does not require the use of other products. If you have concerns with your pet, we encourage consulting with a veterinarian to determine what's best for your little one's current health care needs.

I had tried the thunderease brand one and thought it mite be working so I ordered this one since it last longer. This was delivered but my dog was scratching alot and soon after I took it off she was not scratching so much. Will see if one of the local shelters wants this unused one.

Love these collars

These collars have made a difference. We did make some changes in our routine to help the dogs but the collars are a huge help.

Will purchase the Zenidog flea again in the future

I have been using NexGuard and flea and tick protection for a few years. I hesitated because I’ve read about that many oral medications have caused seizures in dogs

I have been using NexGuard and flea and tick protection for a few years. I hesitated because I’ve read about that many oral medications have caused seizures in dogs. Therefore, I was excited to try the Zenidog collar for an alternative option for protection. It worked great. It was easy to put on and my dog didn’t mind wearing it.

Ultimate 4th of July Test!!!!!

I used this in my home in California during the July $th holidays. I put it on my Chihuahua on July 2nd and it's still on her ( July 8 ). To be honest I picked the worst stress day of the year asa fireworks are going off non stop leading up to and beyond the Celebrations. It showed a bit of promise at first but as the fireworks got louder and more frequent it didn't do much to calm her down. She has a spot she goes to under the bed and that's where she spent her time during all the noise. The request for this review came after I had it for only a few days and it's supposed to be good for a month so it will be incomplete. So far I can say it does not work for extreme situations ( LIKE FIREWORKS ) so maybe a sedative along with the collar would be better in these circumstances.

I'm thrilled with this collar! My anxious dog, Munchkin, has been relaxing more, despite the noise from new tenants, which usually triggers his stress. Previous remedies didn't work, but this collar has been a game-changer, especially during the recent thunderstorms.

Worth a try

I have 6 dogs and I choose Buckaroo to wear the collar because he is my “ special” doggie. It fit well, no odor detected. He is a cavapoo so I trimmed it some once

I have 6 dogs and I choose Buckaroo to wear the collar because he is my “ special” doggie. It fit well, no odor detected. He is a cavapoo so I trimmed it some once I fitted it to his neck. He never stopped scratching his neck area. I did not see any allergic reaction on his skin so I kept it on for several days to see if he would adjust. It didn’t do what it was designed to do for him at all. Eventually after a week of him scratching and rolling on the floor trying to scratch his neck area I removed it. He is back to “normal”. It may work for some dogs but not Bucky.

Could be okay for smaller events

I let my little dachshund use this on the 4th of July when the fireworks are going off and he gets very anxious. It didn’t seem to do anything much for him, but

I let my little dachshund use this on the 4th of July when the fireworks are going off and he gets very anxious. It didn’t seem to do anything much for him, but I’m not sure if this was too big of an event for it to work. It didn’t irritate his skin or anything which is what I was nervous of. Overall I would try this again as I love the idea for a car ride or something less anxiety ridden.

Not great on a furry dog with a flea collar

I really wanted this product to work perfectly on my dog, Azalea. She has anxiety issues especially around one of my foster dogs. However, it doesn't seem to have made an improvement in her temperament. I'm not sure if it's because she's so furry or if it's because it's next to her flea collar but she's the same cranky Azalea that she always is.

Calmed down anxiety barking

My dog went from not barking at delivery trucks pulling into the driveway to Cujo. Frantically running around the house and barking incessantly. She’s 5 years old. Never used to do it. I put the collar on during the day. It has helped tremendously. No odor. Lightweight. Easy to put on and take off. It eases her stress when I leave the house too. She’s back to normal.
