How to do it? Start simple obedience and training activities for Little Jack from day one. Do not be embarrassed that he is still so small. Small, but very smart. Don’t expect miracles of obedience right away, have patience, be consistent, and be persistent.
The lessons should be very short at first, literally 1-2 minutes. Gradually, you will increase the time, but still no more than 30 minutes, otherwise it will be difficult for Jack to concentrate his attention on you.
