    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 5 out of 5 by from Amazing Changes I have purchased two of these. My dog is a rescued Chihuahua. He would growl, bark and bite anyone new and he was so unfriendly to my wife and I that I almost got rid of him. He constantly hid under our bed for hours at a time. I tried the collar. Within a week he started to calm down. After 2 - 3 weeks he was so much better, it was amazing. He still hides but usually for only a few minutes at a time. He doesn't growl or bite my wife or me. He still barks at guests but he doesn't bite and rarely growls at them. He's getting better all the time. As he's calmed down he's learned that people won't hurt him. After about a month, he lost his collar. I didn't buy another one right away because I thought he was so much better. He starter regressing. I got a new collar and almost immediately he got better again. I will try and wean him off it sometime later but for the next several months he'll still be wearing one.

    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 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 1 out of 5 by from Didn’t get a chance to see if it worked I bought the collar today at work and as soon as I got home I put it on my dog. In less than 4 hours he hag gotten it off and chewed it to pieces. The collar came with no instructions. I figured it needed to be cut once fitted but I wasn’t sure which way to insert it into the cutouts (2) and be able to have the end placed through the “belt loop” to keep the end from flapping around. As I mentioned there was instructions or information provided with the collar such as not to wear when in water (found this info on website) or what to do if consumed by your dog. If I knew how to properly put the collar on to avoid the same situation from happening again I would like to try it again. PS I agree with one of the other reviewers that the perfume smell is a bit overwhelming and also made me a bit nauseous as well.

    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 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 5 out of 5 by from Wonderful product I just bought the Calming collar for my 3month old Doberman Pincher, He was horrible and was very unfocus, or like a very bad case HADD. Put on the collar within 2 hours I see a huge change in him. He wouldn't sleep through the night and pacing and whining . We happy to say Thank you , he a whole different puppy. I got a whole night's sleep, no pacing or whining, from me or the pup. I highly recommend this to anyone with pup or dog issues, I could almost say miracle. He so much calmer and lovable and focus.

    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 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 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 Seems to work but the scent is atrocious I bought this yesterday and it seems to work to take edge off my very antsy Dalmatian, but the "lavender chamomile" fragrance of the collar was so strong that it was giving me a headache and after trying to put up with it over night (my dog sleeps in my room), I ended up having to throw it out.

    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 4 out of 5 by from Calms doesn’t Train Miracle works like a drug, but if you are thinking it’s not going to take the place of training your dog. This eliminates stress that can cause unwanted behaviors. For us our geriatric boxer mix had become anxious when our other 2 dogs passed away. She constantly paced back and forth, would walk in circles and when we left would work herself into a panic. We actually thought she may die it was so bad. We had put her on medication but all it did was drug her. The collar is different it makes her feel calm so that at 15 years old she can get the rest that her body needs. The only downside is that some may not care for the smell and I’m not so sure that the collar works for a full month. I’d say it works great for 2 weeks then we start to see a difference. It does get costly not lasting a full month but it’s better than the alternative. Another option is to cut the collar in half and zip tie it to her regular collar and seal the remaining half back in the package. You can extend the use to a full month that way.

    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.
