I'm old school too. I use rawhides. Under supervision. Seems to be taboo these days.I know the current phase people are in is to never let their dog chew on anything. But in 20 years of fostering dogs, we've always used rawhides. We've never had a dog choke and there are times I've had 30 foster dogs at a time! I get many dogs I think are going to need professional cleaning. then a month after having nightly access to rawhides, their teeth look so good they don't need it. The rawhides available now are not like the ones 20 years ago. they are made differently and dissolve better. We hand them out after they eat, and they chew while we are watching TV. At bedtime, I pick them all up, till the next day. Of the many types we've tried, these are the two that are liked the best by the dozen dogs we have: https://www.chewy.com/redbarn-naturals-bully-twizzle-stix-7/dp/45954 and https://www.chewy.com/redbarn-peanut-butter-filled-rolled/dp/46150
After a month, most dogs gums and teeth will be 75% better. In 20 years, I've had 2 dogs that seem to have an inherited tendency to have inflammed gums. They are also the only ones that will get bad breath. Those may need professional cleaning, and brushing, with a chlorohexidene based gel.
