My experience is like yours (I've shared that space b4 lol ) . I have a 2yo male that I work with from a pup . I started him out @5mos. on 2 pet rabbits ( bait & chew ) .Once I got them to run the game was afoot in the backyard . However in the field it turned out to be a nice walk communing with nature . For 3mos this went on much to my chargrin .Then one day in the 4th mo. the lite turned on . OMG what is he doing ?? Oh wow he's hunting.So shocked I actually a rabbit was chasing him . So I tell people that he started hunting at 10mos. but by 1yr you'd think he was a veteran .
