Although tiring, I just treated Max like a toddler! When he tried to eat the plants,steal my shoes,chew the chairs etc, (Remote Controls were his favourite)I just said a firm NO and removed him from the object and give him one of his toys instead to play with. I have never moved objects away from him just keep removing him and eventually he just got the message, if I said NO he just left it alone. Have to be a bit patient though!!
