I'd have to go with not bothering BUT I'm not a novice and would (hopefully!!) know when to involve a vet, and when it's not necessary. For a novice breeder, it can be helpful to know that mum is empty, and that the puppies are all healthy - it could be possible to miss something a vet will pick up on.
On balance if everything seems to be proceeding normally (quiet puppies, other than when nursing = a happy healthy situation), I don't think you need to bother.
As Basset puppies change drastically from day one through to week 5+ I don't let any potential buyers come to see before that age. Their ears don't come down until around that time +, and that could be disappointing to the new Basset owner!! And even then, I tend not to allow touching - all too often people go from kennel to kennel, bringing any infection doing the rounds in. I have them take off their shoes too. And if there is a need to touch them, they have to wash their hands! That may be ott (bearing in mind that provided the puppies have taken mum's colostrum, they should be protected up to around 5 weeks when it starts to drop away) but for me, it's just not worth risking infection getting in.
