So my puppy has had a operation so is crated to rest..she an French bulldog so very bouncy and excited..we sprayed this and it really does help..doesnt last the longest but keeps her calm as she hates the crate (vets orders) the only thing I would say is the smell is disgusting that’s why I’ve knocked a star off..people who came in would comment on the smell.as well..but apart from that it worked ..
