Too many folk over complicate stuff with regard to training dogs.
Make it your mate and lay down firm and clear rules and boundary’s.
Get it used to ferrets and stock, other dogs and the great world outside.
Get it’s recall working.
Take it out and show it lots, it will start to mark naturally, don’t over praise it for marking.
Play tug and piss about with it and it will naturally begin to retrieve usually.
Most of the rest of ferreting work it will learn on the job.
