Well -- it is difficult to get a puppy from ethical, dedicated breeders, in part because they don't have that many litters. I know a number of breeders in New England, and right now I don't believe any of them have puppies available.
Keep in mind that while there are usually one or two pups in a litter that may be available at eight weeks of age, breeders hang on to some pups to 'grow them up' a bit, looking for their next show dog. Bassets can take a very long time to mature, which means you could wait for awhile. It can be discouraging.
The show season is also in full swing now, which means everyone's on the road chasing down points.
Have you contacted all New England breeders listed on the BHCA web site? If one doesn't have anything available, they would probably know someone else who does.
