I got a bully stick for noah after hearing about them on here and he wasn't interested in the slightest! perhaps the novelty wore off for yours or wasn't a tasty batch? ha.
Wow, we have the opposite problem! I can't leave bully sticks sitting around because Kerri would keep chewing on them till her gums bled! Someone suggested they would be able to pace themselves better if they were out all the time so I tried just giving them out and seeing what happened. Copley can finish a 12 inch stick in about 45 minutes- so that happened, then Kerri chewed hers for 2 hours straight until I took it away. We have bully stick chew time now for a half hour a day or so after walks. Maybe try a different brand? I get mine from best bully sticks and although my dogs equally like odor free and not odor free you might want to try the more smelly ones, they might be attracted more by the smell of those.
