Don't know who's breeding Old Style in Qld. Will have a looksee. I know a few around the Childers area who are darned good breeders, and one in brissy but none of them actually have puppies at the moment.
Will PM you details, you can look into each breeder at your leasuire, contact them, discuss and see who you feel most comfortable meeting/dealing with. Know of Old Style breeders in both Vic and NSW, but as I said, not Qld.
You keep saying you want a healthy dog? What exactly do you mean by that?
GSDs come in a myriad of different colours. I assume you are wanting the most common black and tan/black and gold?
Lots of puppies around OZ ATM.
