What I've read says the same.....after an hour of hard contractions and no puppy, see the vet. You could try doing traction on her belly timed with a contraction. What you do is firmly stroke downward (toward the rear legs) as she has a contraction to help her deliver. If that doesn't work, the vet is likely your next option.
copied this post as reminder to myself..
the traction mentioned above...
should that be done along the back
or the belly?
