I would not personally let him cry that long.. he is too young to be away from mom and he needs you... I let them go to sleep and when they are right out of it, I then put them in their crate.. that way it is so much less stressful for them... that is one reason why 12 weeks is the best time for a person to get their baby.. mom does so much training and playing and loving them and that 4 weeks makes so much difference to them...
Hope this helps... just love him and let him sleep, then transfer him.. if he wakes right away.. then not tired enough.. but keep a puppy awake playing at night until they are really tuckered out... |
