Pepper, my Dalmatian, just recently in the past year has started getting into the trash. I put a gate across the kitchen doorway, plus a chair pushed against it for extra support. He pushes the gate out of the way with his nose and slides the chair to the side with his paw just to get into the kitchen. I have tried everything I know to get him to stop but he manages to find a way into the trash. I dont even know why he even started in the first place. I am now putting the trash can in the bathroom with the door shut when I leave. What can I do to stop this nasty habit.
