I absolutely love this. When my dog starts to get upset she will not eat anything, so the chews don't work. I just spray it on her collar and she calms right down. I sometimes think she actually asks for it. I will continue to use this product.
I initially purchased this product to help keep my dog calm during a 6 hour flight. She was settled and quiet the entire time. It worked so well, I regularly spray her beds and crate with it.
