usually start at 12 months with breaking them in to the lead kennels and traps with a few 300 yard runs at the track, then keep them away from the the track till 15 months for qualifing in between that time just walking and getting use to the tread mill but no heavy work
first qualifing run then start again with them bfore second qualifing run and away we go lol
i have found over the years you can pretty much tell what you have by 2/3 time at the track
yes there will alway be one to surpise you but not often
i do work them pretty hard for the break in period prob harder than most

yes i break in alll my own pups i find it better that way as you learn pretty quick what you have and there differant needs
