Have you tried contacting GAHH for an approved shop? I sent them an email and had a response with a variety of shops in the Chicago area within 24 hours. Granted it was only "GAHH approved" shops and not recommendations from this forum...
Sausage dogs are great (been through a couple myself)! You know that the "powers that be" have a sense of humor when you look at a Dachshund!
