Blanket Roll
Prerequisites: Roll Over & Hold
This is a trick combining both aspects. I will show you the whole 5 part series of how I shaped this with Emily. Each video represents a different session and as you can see the foundation takes a few sessions to get laid down. I could have held the blanket and asked her to hold it but I wanted to shape it. But you should know at this point in her training I had shaped her to pick up things so if your dog doesn't pick up random items that are not toys you might need to work on that first.
This was done like 7 or 8 years ago, now I am so much more skilled I could have quicken the process with better reward placement. I would have started to reward her with my hand with my palm facing down so she was twisting her head lower towards the ground as she got the treat, this would have supported the movements I wanted next.
