You should bring in a radio flyer-sized wagon for him to pull for you. Easier than dragging a bag across the floor.

Oh, I have pull-carts for ME to use (and they help get things across the multiple changes in floor level that a wagon and dog would not handle well), but none were in evidence this time when I needed them. The lovely thing about F is that he does not need a training with a particular item or process, but is glad to lend his dog power in unique situations and to follow the person's lead to get it done.
