I've now found the oz one
http://members.ozemail.com.au/~gentest/services.htmlSam, if any of these labs have the test you are looking for but not in your particular breed, they would probably be willing to run your dog through a test (for a fee of course) to see if it does carry the mutation that they have a test for. Some conditions are the same throughout breeds so one gene test can be used on all but there are others like PRA that has several different forms.
If it came back with a negative, it wouldn't help much as your dog could still carry the condition just not that particular gene that was tested for, but if did show positive, at least you would know and the lab may then be interested in developing the test for your breed.
