Long Island Bulldog Rescue covers the Northeast including NH and has mostly english bulldogs. They have mostly adults but they sometimes have younger dogs/puppies. You can apply for adoption at
http://longislandbulldogrescue.org/i...n-application/ (must re-apply every 6 months) or follow them on facebook at

There are lots of scams and poorly bred bulldogs so I highly recommend Long Island Bulldog Rescue (LIBR). I have fostered for them and can attest that they truly care about the health and welfare of their dogs. Most dogs are placed in a foster home first to evaluate their health and behavior and then they are available for adoption.
If you are interested in fostering the foster application is available at
