Comes in a spray form and an electric plug in form available online or in pet food stores. I know they have a cat version, but not sure if they have a dog version. The pheneromes in the spray calm my cat before travel. We spray it into his carrier before we leave. We don't have to use the plug-in anymore because our cat is used to travel. There were good coupons for $10 off that you could get online. Just download the coupon and use in stores. Check it out by googling Comfort Zone.
