Depends on the state. Using bait and dogs for bear hunting in Montana, Oregon, Washington and parts of Wyoming is illegal, there’s probably others too.
Here in Wisconsin they use bear bait which is sugary gooey stuff including old doughnuts etc. They then chase these poor creatures on ATV’s with loud hounds each with a GPS collar until the bear is up a tree and then a shot to the head. I get in trouble saying this in mixed company, but I think Wisconsin bear hunters are pussies.
We only have black bears though.
