Bully sticks also smell like crazy. But they do the trick. Some of my other favorites for time consuming:

Beef knee caps
Rib bones
Kongs with safe peanut butter (I’m sure you knew this one)
Tracheas (they don’t take much time)
Ligament bones, or plain ligaments
Dried jerky sticks

And of course, I’m always an advocate for feeding them out of trick bowls or treat dispensers, makes a huge difference in the evening
