i brush as often as they allow... i use cet toothpaste they have poultry flavor that my guys like best,, CET also makes chews i never found them in a store s i buy online,,,it has the same enzyme in teh chew thats in the paste i also use plaque off, by proden,, its a tinly little scoop that is put in food. i just had both of my dogs teeth cleaned and trying to put it off for as long as i can for next time. i dont know about the liver treats for teeth i know thats is what works well for tear stains,, its whats in angel eyes, i just buy the dehydrated little cubes of it and it does the same thing and is way cheaper |
