My poor dog is very anxious and a nightmare in the car. Whimpers and shakes and very sick within 5mins of a journey. Used this and she was definitely less stressed. We stopped after 1hr of our journey for her to have a break then carried on for the last hour of our journey. As we stopped, she was sick but I think she’s just travel sick. It did reduce her stress levels though and 2 days later when we travelled the 2hrs back, she actually slept a lot of the journey and no vomitting at all.
Not so fussed on the smell but can put up with it for her.
