Ineffective and expensive.
I didn't notice a difference when using these collars. Be aware that they a one time use product, which makes them very expensive. I won't be buying them again.

No recibí la talla que compré (4 collares desperdiciados)
Compré 4 collares talla LARGE para mi perra, y recibí 4 collares SMALL. No le entran, además que son la mitad de estrechos que su talla LARGE… parece piola, temó que se podría lastimar o ahorcar por ser tan finito. Adicionalmente, puse mi esperanza en esta compra. Se avecinan los fuegos artificiales de fin de año, que en mi país y ciudad (Ecuador, Guayaquil), son una tradición. Cada familia quema un monigote lleno de cohetes y fuegos artificiales a medianoche en el cambio de año, por lo que la ciudad asemeja a estar en guerra, con las casas estremeciéndose ante tanta pólvora reventando en cada calle y descampado. Mi perra la pasa realmente mal, y sus collares Adaptil son muy importantes para lograr superarlos… este año, nos falló, pues los collares no le quedan. Los compré y le pedí a una hermana que está visitando mi país por las fiestas de fin de año, para que nos trajera los collares. O sorpresa! Son talla SMALL… no le cierran alrededor del cuello de mi perra. Muy irresponsable la empresa ThunderEase al enviar la talla equivocada. No saben el daño que nos están ocasionando al tener que pasar sin collar el Fn de Año. Mi perra ha usado collares Adaptil desde hace 10 años, pero en otra empresa (CEVA). Desde hace un año, los empezaron a vender directamente en mi país, pero se agotó la talla de mi perra (Large), por lo que los pedí por Amazon a esta empresa, ThunderEase. Craso error. Los primeros años, los collares prestaron un servicio invaluable. Pero no use solo el collar, también el spray, pero lo encontré poco práctico, pues al ser hiperactiva y reactiva, no se quedaba quieto en un solo espacio. El collar nos sirve más. También trabajamos juntas en educación amable, técnicas de reducción de estrés (no todo funciona con todos los perros, por ejemplo los Thundershirt, volvieron loca a mi perra, y terminó atacando a su adiestrador… yo he aprendido a escucharla, así que no insistí y no me llevé ningún mordisco). Para el 31 de diciembre, o en ocasiones de alto estrés, como un sismo fuerte (en el 2016, en Ecuador atravesamos por un terremoto 7,8 y cada tanto tenemos sismos superiores a 5 y 6 de magnitud(, o tormentas eléctricas muy fuertes, utilizamos varias técnicas y ayudas, las que unidas, nos permiten superar esa noche y días (la quema de monigotes empieza el último día laborable… cada empresa u oficina quema el suyo) y finaliza los primeros días de enero. Usamos aromaterapia, musicoterapia en la habitación y ruido blanco en las dos habitaciones aledañas, collar Adaptil, L-Triptofano, bloqueo de ruido en las ventanas, Kong cargados, juegos de olfato (alfombra olfativa), tapete para lamer… y armo un refugio para ella y mi persona en el vestidor, entre el baño y el dormitorio. Al no tener ventanas, es el mejor sitio para estar, aunque nada detiene el estruendo y el crujir de la casa por las cargas de pólvora en los monigotes cercanos. Con los años, he ido mejorando la insonorización de este espacio y aumentando los juegos olfativos y de lamida para tenerla entretenida, lo que nos permite poder dormir un par de horas al menos, durante esa noche. Aunque no sé qué tanto de ese sueño se debe al cansancio por los ladridos y los gemidos durante las horas de la quema de monigotes. En la empresa CEVA, es probable que les hubiera dado 5 estrellas, pero he leído algunos reviews en este producto y empresa, y ya no estoy tan segura de su efectividad. Tal vez han sacrificado calidad o cantidad por precio. No lo sé. El collar talla small que abrí, es la mitad de ancho del que usaba… tal vez los están haciendo demasiado delgados también.

Amazingly helpful, my go-to for anxious/sensitive dogs!
I regularly use the Thunderease/adaptil pheromone collars for my dogs, and have for 7 or 8 years now. They are a huge help for us and can be a big help for many types of anxiety and fearfulness! They also make a travel spray (I didn’t use much or in enough situations to compare and evaluate effects) and a plug-in diffuser for the home (I sometimes use that and it works well too, but takes longer to build up/have an effect, and of course you can’t leave windows open so I tend to use that more in summer/winter and occasionally in a smaller area where my separation anxiety-prone foster stays when I leave). I find the collar works best, and the effects kick in the fastest/within a day or two days. It is body-heat activated and a releases pheromones that mimic those released by canine mothers while nursing, and for many dogs it can help provide some level of overall calm. It makes a HUGE difference for my two especially (not quite as much for my foster) - can see less stress in them the day after I put it on. Each collar lasts about 30 days and I do notice as when it wears off - more anxiety/anxious behaviors again, plus they are more stressed and get a bit crankier with each other. I wonder why… and then check the timing of when I put the last new collar on - and that’s how I realize how much it’s helping!! Having three sensitive dogs I am well-versed in canine body language, and this is my go-to calming tool because it is so helpful. It may not help with everything, and doesn’t “solve” trauma and emotional needs not getting met - positive behavior work and understanding/respecting/supporting your dog’s body language, needs, and unique preferences is of course important, especially for deeper change. But this collar/pheromones takes the edge off so that they are not so sensitive and responsive to stressful triggers! Currently I’m using on just one of my dogs and it helps her feel more confident and secure. If we have a stressful event coming up though, I get collars for two or all three dogs. Some dogs don’t get much of an effect apparently, based on reviews years ago it either worked great or owners didn’t notice much effect. I've personally seen amazing results for mine and a few others so it’s definitely worth a try! (FYI I have also tried a couple other cheaper brands, but they don’t seem to work much/as well as the Thunderease one. Plus some other brands have very strong scents, which for a dog’s strong sense of smell might be highly uncomfortable, especially in a new and potentially stressful situation!)

Works but not very long
We are repeat buyers. On number 14+. Our purchases are buying 1 or 2 at a time because of bad experiences with aitocharging items. Therefore we do not benefit by the lower rate. Sadly. The product works well the 1st week, then declines rapidly the 2nd week & barely makes it to 2 wks. Therefore we give 3 stars. This product has a strong oder even tho the pharemone should not have oder. While we support the results of this collar--when its opened new-- the longevity & price for poor longevity, are not impressive. Thunderease needs to do better. Thinking we deserve a better price or freebies about now.

ThunderEase Anti Anxiety Collar
For one dog it worked great! It was like night & day with him. For the other dog there was no difference.

$20 to play a little game of “will it help?”.
Update: I have purchased this again. The zip tie for the collar has helped, and his bestie has left it alone. Perhaps the smell is deterring him from helping to get the collar, I am not sure. This is the first collar he has not helped team werewolves with. Original review: I have a tiny werewolf with huge separation anxiety. Spinning in circles like a tornado, and barking while he spins-he is great at multitasking. Obviously, I am not the team leader, that title goes to Team murder mittens. Specifically, his bestie in trouble… my void. I have given this collar almost 2 weeks. It is not on him tight, he has a double coat and I didn't want it on his skin, just close enough to get warm since that is how it is activated. The collar is adjustable, soft, and you can cut it to fit. I also used a zip tie to ensure any extra didn't flop about, and it would stay on securely. Kind of like a belt for your belt. Lol. Because knowing my luck, he would find a way to get it off with the help of his bestie. This is why they are always naked, they help each other. I gave up on collars-see photo with my void son modeling a necoichi collar- it lasted for that photo and it was off and under the couch. Verdict thus far: It has taken the edge off. He is not Cesar Milan calm, but he spins less, and his separation anxiety freak outs are less intense. He thankfully has NOT been able to get it off. He is the most high energy, non food - non toy motivated, texture sensitive (absolutely hates metal or concrete or shoes on his paws), mind of his own-good luck everyone else while he holds up the middle digit of his tiny paws with a wicked smile- doggo I have ever had. That being said, he is an excellent guard dog, and he is very brave for something so small (only looks big because of his coat). He just happens to want to be held in your arms indefinitely. I think this is worth a try if you’d like to see if this will work for you. 10/10 the tiny blessing for our family.

Just another fancy collar - Mixed results
I really, really wanted this to work. Our dog struggles with anxiety, and after reading about pheromone technology, I was hopeful that the ThunderEase Calming Collar would be the solution we’ve been looking for. The Reality To be fair, it wasn't a total failure. We noticed a very minimal improvement in behavior, but it was so subtle we almost had to convince ourselves it was happening. If you’re looking for a "magic solution" or a silver bullet for anxiety issues, this isn't it. Pros & Cons Pros: Easy to put on; didn't have a harsh chemical smell. Cons: The results simply don’t warrant the price tag, especially considering you have to replace these every 30 days. Final Verdict For the cost of monthly replacements, I expected a much more noticeable change in behavior. It might work for dogs with very mild "jitters," but for anything more serious, it feels like a waste of money. We won't be buying a replacement when this one expires. Save your money and look into other options.

Nutzlos. Schade.
Ob mein Hund dieses Teil trägt oder nicht, macht absolut keinen Unterschied. Kann daher die Wirksamkeit nicht bestätigen. Schade. Aber die Hoffnung stirbt zuletzt.
