[nagdu] teaching retrieving without encouraging scavenging

[Danielle Cyclorama]

Hi all,
I'm thinking about teaching my dog to retrieve objects I drop. He loves to retrieve and this seems like a useful skill. He already knows how to retrieve a few items by name, but I'm hoping to broaden this skill to include any object on the ground. However, I don't want him to think it is OK to pick up food I drop. I'm thinking I may teach him to retrieve on command rather then automatically if something falls. Any suggestions would be appreciated.
