    Rated 4 out of 5 by from Miracle This collar worked to calm our 80 lb lab Bailee with her anxiety of riding in a vehicle within 5 or 6 minutes of putting it on her...Very happy with it.

    Rated 1 out of 5 by from Disappointed My puppy has been having a hard time relaxing in her crate so I thought I would try this collar. My local pet store only sold it in the 3 pack, so I spent over $50 on a product that showed no results. There was absolutely no change in her behaviour even after wearing the collar for 3 weeks. The collar does not fasten very well and I was frequently putting it back on my puppy as it had fallen off. It has now gone missing in our backyard as it fell off when she was playing. I have two collars still in their packaging and have no intention on using them. Huge waste of my money.

    Rated 1 out of 5 by from Nothing yet Bought this about 4 days ago and my 9 month old long haired chihuahua puppy still barks at every noise she hears. Bought it because of the 4th of July fireworks that go on around our house every year, we live outside city limits. Hope it starts working soon!

    Rated 1 out of 5 by from very disappointed I bought this for our 6 month old lab when my parents were coming to visit. Before arriving, I made sure he had it on for at least a week. We saw the same excited behavior that we always saw when my adult kids came to visit, nothing different. The only thing that I did notice was that when my parents came, he did start chewing on the rungs of the kitchen chairs when he wasn't getting their attention. I've taken the collar off and they've returned to Florida. Before using the calming collar, I also bought the Sentry calming toy that looks like a fuzzy bone...He chewed that right up. I thought the collar would've worked better, but didn't. It smelled nice, but my dog obviously didn't care about that. Very disappointed that it didn't work after how much it cost. : (

    Rated 5 out of 5 by from OMG Really works! I was ready to give our new Lab puppy away, you couldn't stand her. She is now 8 months old and I tried one of these collars. You can actually pet her after only few hours. I cannot believe it is the same dog! This is a miracle, honest. We played fetch this AM and she brought the ball back and dropped it!!! I am buying a case of these!

    Rated 5 out of 5 by from Will be a continued buy The 30 days of my first collar is almost up and I will be buying another very soon! I bring my Aussie Shepherd to work with me (dog daycare) and he paces and whines when he can see me walking around. I bought him to work wearing this and he was like a new dog! He was happy to play without looking for me constantly and was relaxed and calm in his suite during the breaks. Have seen reviews that say it falls off but i haven't had any issues with that considering he plays very rough and has other dogs hanging off his neck fluff every day. Love this collar!

    Rated 1 out of 5 by from Too much perfume smell I'm not sure why the collar has to have a perfume. I can't imagine the dog cares. But we did. We had to take it off the first day. The perfume was way too much for us.

    Rated 5 out of 5 by from So helpful! I bought this to use on a dog that has suffered from separation anxiety off and on for 8 years. She recently became an only dog again and started howling all day, pacing in circles, heavy drooling and constantly wanting to be in my lap. Within 5 minutes of putting the collar on her, she is totally calm and juse longoing on her bed. Best product ever, works even better than the prescription she was on 8 years ago!

    Rated 1 out of 5 by from Overpowering smell! I tried this to calm my anxious foster dog. I took it out of the box and put it on him in the car. The camomile smell is so unbelievably overwhelming I had to drive with the windows down. We got home and the smell is still so strong I can’t even have him on my lap or next to me on the couch. The smell is so strong it gave me a migraine I can’t even imagine how horrible it is for the dog WEARING it! Absolutely horrible I don’t care if it does work I physically can’t handle him wearing it so we’re not going to find out.

    Rated 1 out of 5 by from Made my 1.5 mastiff pit mix very ill Day one I noticed she was scratching at it but thought it was because she never wears a collar is was uncomfortable. Went to work the next day and when I came home I noticed her hair was falling out all down her back. Have her a bath and went to bed. Woke up to all her hair gone, covered in hives and open wounds from scratching. Took it off threw it away and gave her another bath. About a week and half later the hives are finally going away but all her hair is still falling out and she won’t stop scratching.

    Rated 5 out of 5 by from Fantastic product. We have been using this product for a few years and it has been a literal lifesaver. We were at the stage of considering having our much loved stafford with severe separation anxiety put down. The difference that it made is wonderful and I thoroughly recommend thhem.

    Rated 1 out of 5 by from it didn't work I have a 4 year old Yorkie and bought the calming collar in order to try treating him to get adapted to a new home and control anxiety when he is left alone (barking). After almost a month using the collar absolutely nothing happened, the only reaction I got was from others saying your dog smells good. So the chamomile worked for some humans but not for my dog. Maybe it works for other dogs but not to mine

    Rated 1 out of 5 by from Did not work on my dog I bought this collar about a week ago . We have had pretty bad storms and my dog is terrified . The collar didn't help at all for the storms. I will say as far as being calmer acting she has been but didn't help with storms.

    Rated 1 out of 5 by from SAVE YOUR MONEY!!! Bought a collar 5 days ago and has not helped a bit, my dog is still agitated with the sound of the wind blowing!! She wines and wimpers more than she did before the collar, so obvisiously THERE'S NO RELIEF, NO BENEFIT IN THIS COLLAR.I was really excited about thecollar when I first saw it and thought if only just a little relief would be nice, but there hasn't been any. Sorry Folks!

    Rated 4 out of 5 by from Fireworks I just purchased this collar on the morning of July 4th this year since the night before was pure torture for my 8 year old Chihuahua. Poor little thing shook all night. We went to a barbeque on the 4th and she wore the collar and much to my amazement, she remained calm. The only time she really got scared was for the super loud fireworks. I highly recommend this product!

    Rated 3 out of 5 by from Working but dog has upset stomach The color seems to be working well for my dog. She has had it on for about 10 days. She has anxiety, especially about noises, but she is not hyper. It seems to have made her less stressed and more playful. But, she has vomited a number of times. I’m not sure that the collar has caused the vomiting but there has been no other change in her diet or routine.

    Rated 1 out of 5 by from Save your money. Bought the collar in hopes my dog could finally make it through a thunder storm without shaking like a tree in a hurricane, or pace back and forth like a nervous parent. This collar is brand new, and no where near the 30 day expectancy date. Do not, I repeat, DO NOT waste your money on this filth.

    Rated 1 out of 5 by from Does not work at all. I bought a three pack of the calming collars to quiet down my young dog. I changed the collars every month, as directed and am on week 10. I have not noticed one bit of difference. He is still hyper and barks just as much as before I started using these collars.

    Rated 1 out of 5 by from Sentry Calming Colar Well it definately must be a breed of dog, because this collar did nothing for our mixed beagle/boxer. Im sorry but I could not recommend this product....our Thunder Jacket is a better choice and medication, for the Thunderstorms and Fireworks

    Rated 1 out of 5 by from Didn't work for us. Bought this collar two or three weeks ago because our dog is petrified of storms; it didn't help her at all. She paced and panted; clawed at doors and could not be consoled. I even cut up a Benadryl as suggested by our vet; no difference.

    Rated 4 out of 5 by from Works well. Great product for calming anxiety. I was introduced to the calming collar in 2010, when I worked as a dog handler in a doggy daycare facility. One of our high-strung, anxious dogs started wearing it and there was such a noticeable difference in his demeanor that I began to recommend it to other dog owners.I opened a pet supply store in 2012 and provided light grooming services, such as nail clipping. I kept a calming collar on hand for nail clips. It only took about 5 minutes to see a dog visibly relax after putting it on.I've used on my own dogs ever since, but have been disappointed with the quality of the product over the years. The original collars were caked in the powder that coated the collar. Since I didn't need it for daily use, I could preserve the collar and powder in a ziplock bag and get a lot of use from it. Whereas the new design is harder to size and barely any powder coats the collar. One of my dogs has dementia and wears the collar daily and it doesn't last the 30 days that the packaging promises.This collar does work well, I just wish I the duration of it's effectiveness was longer.

    Rated 4 out of 5 by from Wow! I bought this about a few days ago, and I see a difference already. My 9 yr old cat has severe anxiety and it causes him to cling to me. He follows me everywhere and MUST be cuddled up next to me at all times (according to him). I also have 2 other cats and two dogs, which "compete" for my attention, and my clingy cat does not approve. He is an absolute sweetheart except when he occasionally feels his space has been compromised by the others. He normally swats and hisses at the dogs and cats without warning, when he feels threatened, and other times he is fine with them. He is a bit unpredictable. Ive tried numerous techniques over the years to no avail. the dogs definitely do not trust him at this point, and cower at the sight of him even when he is being peaceful. Well, after putting the collar on him he immediately seemed calmer. Tonight he snuggled up with the dogs WILLINGLY, and they even snuggled back without fear. Its as if they sensed the peace in him too! I will continue to buy the collars since now my happy lil zoo has finally come together and my lil boy doesnt mind sharing me anymore. He's content as can be! My only wish is that it was a snap collar, ive read reviews that he could get snagged and hurt and for that reason i have it on loosley so he can pull it off if he needs to. He smells really good now too :D
