Hi - I looked at their website and they do have some cute pups at reasonable prices. As far as them not wanting you to come to their home, I thought it said you were welcome to come to their home if you make prior arrangements but would not be permitted to go inside their kennel although you could view it on video. I think they are just being responsible in this respect as people can bring things in to young puppies on their shoes or clothing so it sounds like they are just protecting their dogs.
