I have a 6mo which one parent was clear, the other a carrier. When should I have her tested. I am assuming that she will not be affected, but want to make sure.

What are the signs of EIC?

If the parents were tested clear and carrier, your dog has a 50/50 chance of being either a clear or carrier. There would be 0% chance of being affected. I believe you can do the test at any time.

Yes, that is correct you can test at any time as early at 2 weeks of age. I believe the information is on the Univ of Minn website.

You can send in dew claws, so that's pretty early
