Sissy is a very intelligent dog who figures out things very quickly. She knows how to open a door not completely closed by reach her paw through and pulling back. She is very persistent about letting you know when she needs to go potty. She doesn't take "wait" for a answer. She will bug you to death.  Sissy is laid back. She is very calm and doesn't play much with the other dogs. She prefers people. Probably similar in size. She is not near as vocal as she used to be....just chills but still lets you know when she wants to go out or in or to sleep.
