Watch out man. Pretty sure it's illegal to use dogs to sniff out down game. Stupid as it might be. Good luck man either way but just don't let the Game Nazi see you trying to do the right thing by doing EVERYTHING find your animal cause he will gladly give you a ticket for it.
I think you can go for a walk in the woods with your dog.... No reason to bring a gun/bow, the animal is either down or going to survive at this point. Good luck on finding it.
