My gals used to fight over bullies, so we don't do those anymore. Plus, they would develop a long stringy-type part when softened by chewing, and Luna almost choked one time.
We now use these:
Zuke's Z-Ridge Cranberry Fresh Breath Dental Bone Mini 15pk
This is the cheapest I have found, too. They come in different flavors, we get the cranberry and original ones. They do have way less tartar on their teeth now, and they don't break into pieces or get sharp at all. Izzy eats hers in about 5 minutes (she's my bigger girl) and Luna takes about 30 minutes. They love them
