At this level of training we are looking for your dog to not only recall over a longer distance but also with distractions. That may be through dummies on the ground or a thrown dummy or in an exciting environment ie a rabbit pen. Make sure you can stop your dog self rewarding and set your dog up to succeed. Do introduce distractions one at a time and gradually build the temptations up. You can click and reward at the end of the exercise to show your dog what is expected.
