If you're talking about the hard ones--I think that
would be O.K. Lots of people in our training classes
used either a buster cube or a kong---hard rubber
toys with holes--filled with carrots or peanut butter
or kibble or other doggies treats. If you stuff
them right, the dogs are supposedly kept occupied
for a while trying to get the goodie!
Take care, Lori

Is it ok to leave a pup in a crate with the nylabone unsupervised? Our dogs
never had them and so I just don't know how they break down. Thanks! Karin
