It is important to keep your dogs teeth clean. Ideally you would brush them every day, or every other day. Feeding a food meant to clean teeth is also benificial. Medi-Cal makes an Oral Care food, and so does Nutro-Dental care, and Hills has an oral care food. The food is made in a large chunk, that does not crumble when the dog eats it, so his teeth have to go in and out, in and out, of the hard piece of food. If you notice a lot of tartar on your dogs teeth, then you should make an appointment with your Vet for cleaning and scaling.It is important to keep your dogs teeth clean.
