Use by adding one pump to 100ml of your pet's usual drinking water. It is said to have a dental care effect just by adding it to the drinking water for pets who dislike brushing their teeth. I tried it because my dog hates brushing his teeth. I used 6 drops. It didn't work for my dog, so if you are using it or want to try it, how about it? Thank you for looking.
