This is a good calming spray I used it for one of my dogs who gets stressed out in my husband’s car. She’s fine in my car, I think its something to do with the noise of his exhaust system. The only draw back with this spray is the smell. I didn’t like the smell of the spray. We used it several times for car journeys long and short, but the smell was rather strong to me. It works well and the dog responded well to it. I just had to take her bed out the car and wash her blanket each time.
