Jackie Reilly, it’s a natural spray remedy, you can get in in most vets and some really good pet shops. It’s 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 too ! Try some you won’t be disappointed xxx
