I use the gel - just bc I think the spray is sort of "startling" you know what I mean? So, we just put a bit on our finger - and put in their mouth, rub on teeth just before bed time. We don't brush. We dont' brush bc we're basically horrible, neglectful, unworthy parents - in a nutshell.
Marcel - who has not been on kibble (eats NV Raw) since 4.5 mths old has perfectly white teeth - he is now 1.4 years old. Wylie - who is 3.5 years old - has never had dental work - his teeth have actually cleaned up remarkably just from
being on raw, and intermittent use of Petzlife (we've actually been really lax about it). I just looked at his teeth for you - they are white with a few spots of tartar - nothing to warrant any dental work at all.
