We have a baby gate separating the dogs from going downstairs where the cat food is... it has been there for a year, and she is still bothered by it. I snapped a picture of her trying to get underneath the gate; you can see that our other dog is just fine, but she thinks that if she can get her nose underneath it that she may have a chance. She stayed like that for almost ten minutes. The other picture is of a later self-imposed corner of the room pout! She makes us laugh all the time.
