Jackie Reilly, it’s a natural spray remedy , you can get in in most vets and some really good pet shops. Its truly a miracle product ! You can usually get a small spray bottle to try for about 5 pounds to test if it suits your furbaby. My older dog was so anxious she hated all other animals , she was terrified . Now she so comfortable we can’t keep her away from our new pup ! Use it on our horses to ! Try some you won’t be disappointed xxx
