From now on eating gives your dog clean teeth. The Oral hygiene is important for the health of our dogs. To promote dental hygiene we should monitor if our dogs chew the food, play with dental toys and it is a good idea to offer a bone or snack at least weekly for this purpose. Greenies offer bone shaped toothbrushes with some toughness for cleaning and preventing tartar. Important to choose proper greenie size proportional to the size and weight of your dog.
