I purchased this item for my dogs, a Chihuahua and Stafford, from my vets. It worked really well on them, helping them relax and like others have said, they fell asleep on the settee, while the fireworks were being let off. So I purchased it from Pets at Home for my mums Jack Russell. It didn’t quite work as well, on the Jack Russell, who still decided to bark at every bang! It’s not got a very pleasant smell, but I would definitely use it again at New Years Eve for my Stafford and Chihuahua.
