Have a very anxious breeding dog, spaniel, she’s so sensitive to noise and fireworks scare her and send her under the bed. The vet recommended this and I thought it was a lot of mumbo jumbo but tried it and put it on…fireworks started and she fell asleep next to me! just couldn’t have believed it but tried it the next night. The one night I was away at friends, we didn’t’ have it with us she started getting anxious, scratching the carpet trying to hide behind the tv. So its a must in my house and have recommended it to other pet owners. Better than adaptil….bought the spray as well, not tried that yet.
