I tried registering with the US Shop and had troubles to get any login at all so I sent a message to one of the owners and she said that her admin took care of it.
If you had the same problem and couldn't register send an email to [email protected]
to register with your Club, as a K9 Handler or Dealer (if you have a dealership). They'll need the tax number and address and you'll get your dealer login.
He responds very quickly.
