I too have a 7 1/2 wk old male, he has 2 nights away from his family. I'm crate training him, for 2 reasons: he'll be alone a lot during the day and I don't want him to get hurt while I'm asleep.
I have Diablo in my room at night. I give him at least 30 minutes of vigorous play before bedtime, and last night he settled down after about 20 min. He wakes up 4 or 5 times a night, screaming and crying. Night one I took him out of his crate everytime to see if had to go (no). Last night, I took him out just twice--he did have to go--then we played, he got tired and back in the crate.
I'm no expert, but I've read 2 things I absolutely believe. Puppies this age cannot control their natural urges. And consistency is the golden rule of training. Stay in touch, I'm sure we can learn from each other's experiences.
