I don't see it being done. Not saying a dog won't hunt either,but knowing what time it is when your ready to go. Seems far fetched with out alot of trashing....
i've owned a dog that would tree squirrles by day an coons by night an she was by no means trash she was one hellva meat dog that wouldn't mess with a deer opossum ect. she was a tree dog deluxe
but thats also not a bear or hog but i think it can will an has been done many of times somewhere along the line
(before i die i will hunt a bear behind a pack of hounds an a mountain lion) lol
