This product is worth its price !!! I've got 1 Year old hunting dog from a shelter. Despite weeks long exercise alone to stay, it has all the things destroyed she got between her teeth. From shoes started on carpets, paper, linen. Was even cleared than anything she has not stopped and began to gnaw her basket. As for me did not come a dog crate or strong tranquilizers the veterinarian in question and also our dog trainer and psychologist were at a loss, we came last us to buy this necklace on the idea.
After just one week, we noticed that they became increasingly quiet as we were at home (went constantly to the second dog going on). And when we got home we found no chaos but a quiet dog !!!
One notices, however, once around the 4 weeks that no longer act the Phäromone. She was immediately aggressive to another dog over and destroy the started from scratch !!!
