If it turns out she is partially blind, it would explain so much - just like with Tibby. Thanks so much Uabassoon for bringing this lightening bolt idea to me!
Let me know what happens with your friends dog.

The saddest thing about her limited vision is that she can't see just how incredibly beautiful she is
Oh believe me, she knows. Someone must have told her she was a little furry princess, because she is a total ham. And I'm convinced that she purposely acts cute because she knows how cute she is.
