Make sure you teach him a firm leave It command. Always offer him approved toys when taking your stuff away. By 8-months mine had this down. He does not touch our stuff. I would just remove the sock and firmly say leave it...then playfully toss him a toy or chew and praise and encourage him to play with it instead. You could keep him leashed with you in the house for awhile too. That way if he tried to pick up your stuff you can correct it immediately. Once the shoe has been eaten correction is a bit late. We used a crate in the house, and later a tether and eventually weaned off both. I crated through the night for the first year and just used it occasionally for containment after that. I do not even keep it out now but he still knows what it is if we have to drag it out and use it for some reason.
