Hello, My 7 month old Standard - Steeler has been a surfer from day 1. Now that he is a lot bigger, he swipes a lot. Anyone had this problem and success in stopping the behavior? We yell, he gets down, and back at it again. Pennies in a soda can? Setting him up with a bake sheet with items on it? Just a couple of things the trainer recommended that I have not done yet. ANy help would be great, Suzanne
