My black lab is a heavy chewer and LOVES rawhide bones. I'm hoping that the bone-hard texture in Nylabones will wear down more slowly. Nylabone's website indicates their products promote good canine dental hygiene - always a bonus.Does you dog like any particular Nylabone products? Would love to see comments about any Nylabones - positive and negative - so I can better decide which one to purchase. I will let you know which product I select, and how my dog does with it.
