Have any of you heard of that liquid you put in your pets water that helps freshen breath and prevent tartar buildup?

I've been using it with Nebo for the past few weeks..it's hard to tell if it's working with the tartar (and I brush his teeth a couple of times a week too) but his breath smells nice lol. It works with cats too, maybe you could try it!

This isn't the brand I'm using, mine is from Petco but I couldn't get the Petco website to load...I'm sure they are about the same thing.
