I have a young lab, and she does not seem to like to use her nose. First day out dove hunting, and she made some wonderful marks, often coming within inches of the bird, and then not finding it. It was obvious she was using her eyes and not her nose... In the past, I have used live pigeons in a wet gunnysack to help train dogs... Drag the wet gunnysack with live pigeons over cover, and at the end, place a live clipped-wing pigeon. What are some tricks of the trade that you guys do to get a very visually oriented dog to use her nose???
