This reward placement is actually a combination of a 'left out' and a 'back alley presentation.' 'Back Alley' remains part of its name because the toy, when delivered, actually travels along the path of the back alley we are now familiar with. However, by its nature, this placement actually functions more as a 'left out' because our intention is for reward to appear behind and to the outside of the dog's position.
THERE'S ANOTHER IMPORTANT FUNCTION OF THIS DELIVERY: This reward placement can be used as a transition between the left out, and a neutral picture - meaning when I'm not carrying toy in visible sight for the dog.
Ultimately, we have to teach our dogs to perform with no toy in sight. No matter what reward placement, bridge behavior, or fun tricks we use to train our dog, eventually we have to be able to create reliable and proficient behavior that doesn't rely on heavy reinforcement or reinforcement in sight. Currently, we are relying slightly (especially those of us using toys) on the allure of the toy, which is visible to the dog. Part of the effectiveness of the 'left out' placement is that the toy is immediately to the outside of the dog's head - thus encouraging a straighter alignment. This needs to change. Practicing the following reward placement helps us bridge the gap between a heavily assisted picture and one that is not.
By transferring the toy to our right hand and still ensuring it's delivered to the 'left out' placement, we can maintain the dog's head position while removing the obvious visual aid from our left hand.

Once you've perfected your toss, invite your dog into the mix. This will be a more complicated experience with your dog in the picture so be sure to practice your toss placement again from as static position.
Here are a few things to keep in mind:
