Well as you see with your two every chin has different preferences. My two love apple and pear about the same (favorite of both), but also love willow (weeping willow to be specific). I have a whole assortment though, so I rotate the chew sticks from day to day as to what I offer. Another thing I noticed is with some wood, like blackberry, they don't like it as a chew stick, but destroy it over night if I make hanging toys out if it.
