Pups do not go - it is nap time and all 14 fall asleep at once. It is not the way it works. One may have slept longer or later and be raring to go and another may be more low key as it is their temperament to be so. It is hard to digest that in an hour play session and they do change between 6-8 weeks.
The beauty of us spending so much time with them is we can sort that all out and be honest as to what we see.
Right now this Raven boy is sleeping more as he is younger but he won't be in another week. His skills seem up to par with the older guys. He truly holds his own. I am impressed. You give him a challenge and he meets it.
