I bought it from a local store, before it came to zooplus. My golden retriever suddenly started to be afraid of train rides, to the point of panic - barking and trying to escape. Since we don't really have any other choice - we have to travel by train at least few times a month, I tried several types of sedatives from the vet, to try and get him used to the train again. Nothing worked. By a chance I finally found these and they WORK! He's finally getting used to the train again and mostly calm.
