It definitely does the job. Where the little dog (mini pinscher) used to approach you, you felt the smell; now, after a month of daily use, it is not as bothersome. I believe it is worth it.

It doesn't smell particularly our dog's mouth, so it shows that it is effective. Don't expect results for tartar, it only gets removed with brushing.

It is very effective in terms of the smell of the dog's mouth and quite more economical compared to other products. I do not know, of course, to what extent it is efficient in protecting against plaque, etc.
