Elsa can be cuddly when she gets comfortable with you. She's really loves her sister, Anna, who is fostered with her. They are always rolling around and biting each other. It's really cute to watch.
In addition to her sister, Anna, Elsa lived with two other puppies and a kitten (all three adopted from HSSV). Elsa and her sister played with the puppies. Elsa could definitely hold her own with dogs that are twice her size. Elsa was not scared when I brought her near the kitten.
Elsa takes time to warm up to people. She's not shy, she's just indifferent. If you give her a toy, then she'll pay a little more attention to you. We have one teen in the house (17 years old), and she met extended family (children ages 6, 7 and 11).
Elsa loves chasing after things (toys, blankets, puppy pads) if you hold it up over her. So, I would just move it around and she chases and grabs it. It's the cutest thing. Elsa has the most amazing blue eyes; it's as if she can read your mind when she stares at you. She's an old soul in a puppy body. Elsa doesn't want to be treated like a baby, but she loves to play.
