My pup (15 months) is doing a beautiful recall where she comes running at full speed and is rewarded with a tug/ball. How do I translate this to a crisp frontal sit, without slowing the recall down? I realize she should not come to expect a frontal sit all the time, but I think its time to introduce her to the front sit/finish.

If anyone has advice for training this, I would apprecaite it.

I would continue working on the recall with the dog getting the reward by running through your legs. This should keep the dog fast and coming in straight. Once the dog is accustomed to getting rewarded like that you should pay close attention to your body language when recalling the dog, standing up straight, arms to your side, feet together. The dog should see you looking like that, still knowing that when it gets there you will spread your feet and it will go through your legs (without breakng stride) and get the reward. Work on the sit fronts seperate from the recalls. Work on close tight sit fronts. Use soft food treats if you need to, to get the dog in tight. You can even practice getting the dog in tight by sitting on the edge of a chair and letting the dog come all the way in tight with your legs touching its sides.You should practice short recalls (like 6 feet) to give the dog plenty of reps putting its self in place. Once the dog is comfortable with the sit front you need to establish it as a position. Just like a heel or a sit or a down. Youll know that is accomplished when while the dog is sitting in a heel postion and you give the command and it flips out in front of you into a sit front. Once the dog understands all this then you can start mixing it up with the recalls.
