I've noticed that Daisy does. This morning I was taking her out before I left, and I was running late. She was taking her sweet time, so I griped at her a little. She looked at me like don't rush me but she went ahead and went. When we got back inside I put her in her crate and she will usually kiss me goodbye (lick my hand) but today she turned her back on me and just sat down, LOL. I guess she didn't like being rushed and griped at. She holds little grudges like that all the time. I think it's kind of funny.
