We got our first pup at 6 weeks of age; the law in MD is now 8 weeks of age.
Our mothers have been done nursing the pups by 5 weeks of age (think sharp puppy teeth) and till they were dried up spent lots of time correcting pups for trying to nurse and trying to avoid the mob of pups wanting to nurse.
There is lots of debate as to the best age for pups to leave; 8 weeks is close to one of the first fear stages in Border Collies and may not be the best time to change a puppy's environment. Before the fear stages may be better for the pups.
