It is known in human circles that poor nutrition can lead to poor dental health. I would assume this holds true with dogs too and that dogs raised on less than desirable diets might have teeth that are more brittle and likely to break. If this is the case, the blame of the problem is being misplaced however. Chewing of bones is not the problem but rather the poor quality diet fed during growth should be blamed. Could, of course, be nutrition during development as well. LOTS and LOTS and LOTS of dogs chew on “appropriate” bones without losing and cracking teeth however femurs and other weight bearing bones are not recommended.
