Have you ever noticed that dogs can be trained to not cross over boundaries that they would otherwise be able to pass easily? My Lab never once jumped over the dog gate in the house even though she could have done so easily. She never went in the garage even though my Dad sometimes forgot to close the little gate he put up to block her while he worked in the garage. This video shows a little more extreme example. I think this is a little bit mean. The person calls the dog "stupped" even though they themselves can't spell it correctly. I think the dog had an experience with a beverage can where it was knocked over and made noise. Most dogs learn quickly how to avoid scary things. [media=youtube]udEmgbgxT98[/media]
