Here's an activity that will help your Doberman Collie burn off a lot of their natural energy; jumping rope is a fairly difficult cardio activity even for many humans, as one can jump rope at such as speed that it becomes a high intensity workout. With your dog, you'll want to start off slow and then gradually build to quicker, more intense pace.
This is another activity that's meant to help your Doberman Collie get the hang of commands and obedience training. Toy retrieval refers to an activity in which your Doberman Collie heads out and fetches all of their toys after a play period so that they can be then put away in a chest or trunk. The idea is that you'll want to train your dog so that on command, they'll head out a pick up all their toys strewn about the place.
