My dog was 5 months old when he ran his first live track on a deer I shot.
I started him on short liver drags and hide drags playing with him and teaching some obideince( some my not have took like I wanted ).
Save you up some deer blood and a couple livers and get you some feet
Most professors will save you a liver and feet but you want feet off deer that ran atleast a 100 yds after there shot
