Heart is working out wonderfully for us. She has her quirks (like licking us), but she is an absolute sweetie. She is definitely coming out of her shell too. She is way more confident around people and around the house. We are trusting her off leash now even though she is thoroughly distracted by squirrels.
Best of all, she is turning into an excellent office dog. I am thankful the my current work situation permits me to take her to work. She (and any dog in the office for that matter) is an excellent distraction throughout the day.
She can be quite playful at times too. She is four now, but after having an older dog, and not seeing the puppy-like playing, this is a welcome sight.
