I can see two things right away that I don't like.
1. They start shots at 5 weeks old!!
Puppies should have their first set of shots around 8weeks old, any sooner and it isn't effective as they still have the antibodies from their momma's milk.
2. They sell with Full Registration only, never limited!!
They obviously don't have the puppies well being in mind if they are selling full registration to anyone who will pay.
