I have a friend who is looking to run in HT with his lab. He has been training to duck hunt, but now her wants to put her in tests. Sometimes during a retrieve, she will pick up the long bird first and the on the way back, she will also pick up the other bird, having two birds in her mouth at once. How would this play in a HT? I know about switching, but this is something that I never heard of in a test.
