[nagdu] Picking up things that aren't toys

[Tracy Carcione]

Krokus picks up lots of things that aren't his toys, like my shoes, hats, 
papers, anything.  Really, I don't mind if he carries things around, but 
then he starts chewing on them, and that I mind a lot.
At first, I scolded him and told him sternly to come so I could take the 
thing away.  Predictably, he didn't want to come.  So I started calling him 
cheerfully to come, and praising him when he did.  That way, he gives me 
what he's got, but he doesn't learn not to pick it up.  I've heard of 
trading a toy for the thing he shouldn't have.  How do people manage this? 
Do you pick up toys and carry them around, waiting for the dog to grab 
something non-toy?  Is there some other solution to this problem?
