have a look at the post in the general section "advice for new puppy owners "
hereif you scroll down theres a bit about what to expect when you bring a new puppy home :)
going to a new home can be very traumatic for puppys, new smells sounds etc.... no mum or litter mates.. it will take awhile for them to settle in its only natural.
congratulations on the new pup by the way :)
