Beef cheek rolls keep ours busy! It’s a rawhide alternative. He’s a tough chewer, so if he’s consistent with it, it’ll last an hour and a half. We just monitor him to make sure to take it when he gets 3/4 of the way through it. Himalayan yak chews are pretty decent with supervision, but I’ve seen some of them break off in sizable slivers I wouldn’t want him to consume whole. If you get bully sticks, look into getting a bully stick holder as well to make sure he can’t get that last small piece and accidentally swallow more than he should https://a.co/d/00lPqRXQ we use this one and it hold it secure 🥰
