i have two toy poodles, one is 8months old the other is 6 months.well the little girl mia started digging up the lawn and eating it,and guess what! yes my other toy copies her.I have to have a little chuckle when i watch them in the garden, as when my hubby plants anything one of them is SURE to go and unplant it. lol...i too have found that a crate at night is a god send.good luck with your puppy.

If he's on the leash and searching for stuff to eat whilst been walked, yank him to the side to knock his concentration and field of view from whatever he wants to eat. keep doing this he will soon learn and not been so concerned on what's out their to eat, just make sure he can have the odd sniff though.
