Barney and Roxy are training, both on and off the lead. On lead they’re working on pulling, being the pack leader is vital here, you should be first through gates, doors etc, try to make them walk behind you if they start pulling, you are the leader, not them.
Pretend to have some of the treat first when you reward them, you are pack leader so you get first dibs on food.
Recall training involves a long lead and a secure place, with the lead on call or whistle, whistling carries better so I recommend that, if they don’t come reel them in and only reward when they come to you themselves, not if you’re hauling them to you, repeat this as much as you can, it’s a slow process but everyone wins in the end!
As you can see, smiling for the camera training is next!
