My experience is a bit different to JG's, possibly because I only use the Emmi Pet on toydogs so much smaller teeth and smaller, tight mouths - my large dogs never need their teeth cleaning as they have bones regularly. The toothpaste that came with it I couldn't use because the dogs hated it. I bought an Arm & Hammer beef flavoured one on Amazon instead and they like that. The worst trouble is that they all HATE the Emmi Pet being used. Absolutely detest it. 2 or 3 of them try to bite every single time, the rest give up and put up with it but very unhappily. And yes I did do it all gradually to get them used to it, but if anything they dislike it more for every time.
So I don't do it more than once a week. The older dogs all had a lot of tartar. It IS going, but so slowly that I know that I am going to have to take them all to be done by the vet, so I can start afresh. Some of the tartar isn't shifting at all. I don't know if it is our water perhaps, but the younger dogs in particular (aged 2-4) have really thick all covering pure WHITE tartar on their back teeth, and the Emmi Pet isn't doing anything whatsoever there. Wheras on the brown tartar on the canines and teeth closer to the front, it is going.
If there are sore gums, the Emmi Pet DOES make them bleed. And yes that is without brushing as you are not meant to. I can use it perhaps 5 minutes per dog per time maximum, that is all they will tolerate. So all in all I am not very impressed. It would probably be fine if it was used for prevention as opposed to tartar removal. I'm trying that with my Poodle puppy.
