someone like you asking all these questions throws a red flag to me. im a breeder of treeing walker coon hounds and english coon hounds but my peta/hsus radar just went off with you.
you want physical addresses,you want to look at the pups before buying, most hound breeds are NOT AKC pappered while some are most are UKC or PKC and most folks that know hounds know this.
just from your post,and this is only my opinion, you really sound like you would like to visit someones kennels, maybe take some video, hoping to see bad conditions. JUST SEEMS A LITTLE WEIRD TO ME but, you may be on the up and up and in which case there are plenty of breeders out there
