Call it what you like, but there is no other description I can think of that would cover hiding in a corner because of being humiliated, and then needing help to recover his "mojo." I don't exactly anthromorphise, but I certainly know that animals have emotions.It's fine to disagree.
IMO what you describe has nothing to do with being embarrassed.
Embarrassment is beyond their scope. Its easy to project human emotions onto them though.
