When the bloodhound is tracking blood and barking for the player to catch up, they should occasionally hop a little so they can be seen in tall grass, behind bushes, etc.
Not too often, and their back feet don't need to leave the ground. Maybe only add the hop animation into the cycle after a certain number of barks, enough that could mean the player is having trouble spotting the dog.
Of course the priority should be on fixing the directional audio of the dog's bark (along with the other misaligned sounds) but this would be helpful regardless.
