I have taken him with me out in the field and he has killed a few mice with no further instruction.... however I'm not quite sure if I'm going about this right I would like to eventually get him onto bigger game such as rock chucks, badger, raccoon,nutria,etc. and I'm wondering what age you guys start your dogs and how you go about it and if it's just a natural deal where the dog wants to hunt and he will find his own way or if there is steps I can take to improve his skill and get him even more interesed.....
