I also brush my dogs teeth about once a week. Herc is the only one who likes it done. But mostly I feed them dry food, which helps alot, and give them soup bones from the butcher and pig ears. Felice is almost 9yo and her teeth are better looking them some 2 yo dogs I've seen!

There is a dry food called T/D made by science diet that you can feed dogs/cats that have bad teeth or you can feed it to make sure they don't get bad teeth. The food is large nugguts so the dog/cat HAS to chew it, so it breaks up tarter. You can also feed it as treat to help their teeth..
