This is what an all natural bone looks like - YorkieTalk.com Forums - Yorkshire Terrier Community
I hope this helps you.
I can't stress enough how dangerous Nylabones are and rawhides.
Not only can a piece of rawhide break off and get lodged in the
throat or stomach they also swell up when wet and could cause
a blockage. Nylabones when chewed can break or small pieces
like the size of a grain of salt (tells you on the package) SHOULD
pass. But when these particales don't pass they can cause damage
to the intestines, stomach and bowel track. They are likes little
slivers of glass. I have said this in the past several times and I hate
repeating myself but we get newbies all the time. Buddy was hospitalized
for 4 days due to this. Please find another way to relieve the need
for chewing like a natural bone. You will be safe and worry free.
