When new pups are born, their mother naturally emits pheromones that give the puppies a sense of security and comfort. These pheromones help dogs bond to each other and their mom. ThunderEase replicates these pheromones for a drug-free, vet-recommended, calming solution that puts an end to unwanted behaviors like destructive chewing and problem barking. ThunderEase is effective in treating: – Fear of loud noises like thunder and fireworks. – Uneasiness in a new home or environment. – Stress when socializing or during training. – Problem barking. – Destructive chewing. – House-soiling (or “uh-ohs” as we like to call them). – Travel anxiety such as shaking, vomiting, panting, agitation, and salivation. – Stress when visiting the vet. – Anxiety when boarding or kenneling. – Stress caused by changes in the environment like new furniture or remodeling.

We put it on subscription
For us, this is something that has really made a difference. My partner’s dog is a mix of ‘working’ dogs (collie, staffie, britney, etc) and is always ready for action. Moving my two cats into his space amplified his natural tendencies and training has been slow. I added this collar in a desperate attempt to bring a little peace. Its not magic, and it’s certainly not something that we put on and immediately noticed a huge shift.What we noticed is that around 3.5-4.5weeks our dog is being a louder barking PITA and we realize it’s time for a new collar. After an hour or two he’s back to the calmer version of him, and is better able to respond to commands and his calm down time shortens significantly. For us this is a staple and I bought and extra and then put it on subscription so we always have one in the closet waiting.

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.

Worked Wonders Immediately
Fabulous product. Immediate result! Meet Merlin, my 9 week old Bernedoodle puppy. He’s teething and in the evenings he’d get more uncomfortable because of it, so a bit more spunky. I was going to get one of those plug in pheromone gadgets but that won’t work in our home because the substrate that aerosolizes the pheromones is unsafe for birds. So my friend recommended this Thunder Ease collar and as soon as I put it on Merlin it had an immediate soothing effect. The collar is adjustable and you simply cut off any extra you don’t need. It attaches easily but is secure. It reminds me of how a zip tie works in that once you put it on you pretty much want to leave it on. The manufacturer recommends 24/7 use for optimum result. I was cautious because I didn’t want the collar to have a sedative effect or change the personality of the puppy – and it doesn’t. He’s not drugged, just calm, like he would be when he was feeling safe with his dog mom. The collar is light weight and flexible doesn’t bother my puppy at all. On an adult dog wearing a collar, this could easily be a secondary collar because it’s so light and unobtrusive. Highly recommend.

Pricy but has some effect
Our senior dog has started to get anxious in her golden years and we have put her on anti anxiety, pain, anti inflammatory meds, etc, and while these helped, she still had a base anxiety level that was a bit high. So we gave this a try, and it’s a soft rubber feel that’s extra long and can be cut to fit your dogs neck. It won’t make any noise when moving around and easy for us to take on or off for baths, but it does seem like the effects wear off quicker than 4-5 weeks, so I would say it’s a bit pricey for a month of some minimal effect, but it’s better than doing nothing for her anxiety, so we continue to buy this monthly for our pup.

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.

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