Careful. Anything that hurts to tap on your knee cap can break a dog’s tooth. Ask me how I know

My vet said if you can’t scratch it with your finger nail it’s too tough for a dog.
So…not antlers or water buffalo horns (the two things that gave my dog slab fractures!)
Success with soaking kibble or using wet food and freezing it in a topple toy. Not quite chewing, but takes my dog a decent time to eat her meals.
For actual chewing, I like mumbies (or whatever, there are tons) but they can leave shreds since they are wood.
