Most greyhound owners are told when they adopt a greyhound that they should put something on glass doors such as Post-It notes so that the greyhound knows they cannot walk through it. We are raised in kennels and do not have a lot of real life experience so we have to learn these things.
The Post-It notes were taken down from our patio doors long ago because we know we can't walk through glass. Apparently Mama doesn't know that. The other day she was using the BBQ on the deck. She had a plate in her hand and walked smack into the door. The plate hit her in the stomach and she left smudges all over the door. I ran in to see what happened and had to turn my head so that she would not know that I was laughing at her. Luckily she didn't get hurt and more importantly, she did not break the door. I bet she doesn't do that again.
