At 13 months old in the duck blind yeah the dog is going to itching to go. Don't get discouraged just know that in the yard you need to fix the problem. There are a lot of factors involved during a true hunting environment, just the same as a HT you can't exactly imitate it. Make SIT black and white during training, hold her to a high standard. Go back to putting her on a check cord. Without the dog being cc its hard to keep yard work black and white, results become gray from a nagged dog. Being fare sometimes isn't.
