Try using quality milk bones out of the bins not the bags also dingo bones (you can find them at walmart or pet smart) at about 5-6 weeks ...
a pup will chew on one for a week when the dingos get small I throw them away.
I've never had double canines nor tarter problems, I give them to the babies, teens and adults often, also I send a pack home with the puppy pack.
hope this helps
