Mick is getting clear on the concept of “Down” on command but he still needs a little hint so he can succeed every time. There’s no point in putting an early skill to a test too soon. After a canine student of any age has the idea, the food lure can be a partial movement. After a dog gets that right, you can repeat with just a tiny movement of the treat toward the ground. His enthusiasm shows that he has no anxiety about this. Mick will be ready for the command without the food next. One baby step at-a-time, especially for a baby.
