so, finally home from work overseas and spending the first night with the new puppy. as usual jet lag has me up in the middle of the night so i took the time to watch the hillman puppy dvd to get familiar with it and the question i have is that going by the timeline it looks like by around day 21 he's starting force fetch. that makes that pup about 17-18 weeks old which seems young. i've always been told not to formal hold or force fetch till after the adult teeth come in. Is hillmans technique early compared to others or did i just miss something along the way?
