The problem with these pups are they are so cute - so people tend to lavish heaps of attention on the pup when they are little and this does cause problems later.
All pups need to be taught alone time. Crate training is good for when a pup first comes homes. It does tend to stop a lot of so-called neediness later on.
A lot of people also grizzle about all the damage these pups can manage. My little one is now ~ 10 months old and I have left her free in the house with the older one since she was about 4 months old. No destruction - no toileting problems - so no hassles.
