Greenies and other "consumable" dental chews are NOT safe options, although many vets still think so. They may not break teeth, but they have the potential for worse problems... And I know this from personal experience.
I had been told by two different local vets that "Greenies" had changed their formula, and were now safe. As a result, I started giving Koid a Greenie now and then. He ended up in Tufts Emergency hospital for three days with an impaction, to the tune of $1800. The ER docs there told me that their NUMBER ONE cause of surgical impactions was dental chews. PLEASE don't feed these to your dogs!!! And rawhide is no better, for the same reason. Both these items are not easily digested by stomach acids, so if the dog bites off a large piece and swallows it, it can pass out of the stomach, undigested, to clog up the works in the intestines.
I'm not sure I agree with other parts of this list, either. LOTS of people feed raw meaty bones as part of a healthy raw diet. And "antlers" covers too wide a range of products. I agree that deer and elk antlers are very hard. They are so hard that my dogs have no interest in them. But moose antlers, especially the blade slices, are MUCH softer, and provide satisfying chewing without danger to healthy teeth.
Milk bones have very little "chew factor" to them... Dogs just eat them, and they are extremely poor quality food. Tennis balls shouldn't be left around if you have a dog who actually CHEWS on them... But most dogs just enjoy a nice game of fetch.... And normal tennis balls are too big for the average Havanese anyway.
Kodi has consumed pieces of both the soft Nylabones and pieces of the hardest Kongs. So while those might be appropriate for some dogs, they aren't for all. I have little experience with hooves, because the smell was so bad I took it away!!!
With most of these items, I think you need to watch and see how your dog interacts with them. Are they aggressive chewers? Then they are more likely to crack teeth no matter what. Even if you only gave them things on this "safe" list, and even if they liked them enough to chew on them, they can still go outside and crack a tooth on a stick or a rock. It happens.
