I don't know any breeders in SD - however, have you asked your vet to suggest one? I just checked the National Beagle Club and there are no SD breeders listed there - that doesn't mean they don't exist, just that they're not members of the Club. Are you looking for "pets", "show beagles", or "field beagles"? I don't ship my puppies, but I know many breeders do. One that breeds "pets", but usually with show "backgrounds" is Bandon Beagles in Oregon, they don't charge "extra" for shipping, which many breeders do. I will check some of my breeder friends, and get back to you when I hear from them.
