Mitzi's appetite is different everyday.  Yesterday she couldn't get enough to eat, today she didn't eat her breakfast and doesn't really want anything and probably won't eat until later on.  She is fit and well and would love to go charging around the fields but she is now on lead walking only, which she isn't best pleased about, so I think she is sulking a bit at the moment as she is a very active dog and loves her agility and running around but she is not able to do everything she wants at the moment.
