All my dogs will chew these, though not all the time. They go through phases. Even Vegas, the most picky dog I've ever seen will chew these sometimes. This is the dog that will not eat a cookie (human cookie, a rare treat) without milk. They normally chew them for a few days then won't touch them for a few weeks, then one day I see them chewing on them again for a while. What I really like about these is that when they get too small I can just pop them into the microwave and they puff up and make a crunchy treat that everyone loves.
