This has been a god send, my dog had a trip to the vets for dental work, last time he was fine after surgery but this time he wouldn’t settle in his crate at night and hated being in the dark, this product was recommended to me and after reading other reviews, I decided to give it a try, Its worked wonders, a couple of sprays before we close his crate at night and he settles much quicker, last night we even managed to switch the light off! Happier dog and even happier owners x
