This certainly works for MAN & BEAST, especially after his favorite garlicky meal. I'm talking about a severe case of bad breath here.
We usually have a very stinky house for a few days after DH had this one dish accompanied by lots of garlic. His car stinks for a few days as well. Not only his breath is all that horrible smell, but you can also smell it all over his body because I think that odor comes out with his sweat.
This breath drops not only tastes good, which is a big factor that DH is even willing to take, but it also works almost on contact. In my case, all I need to do is give him some drops soon after he finishes that dish, than add some booster drops a few hours later for 3 to 4 times. Viola, no more stinky house, or car.
I use this with my mastiff who has nasty breath. He thinks it's a treat and when sees the bottle he sits by my side and wags his tail like mad. It's the best ever, puppy kissesa ren't so bad with Burts.
