Heidi is an active, always on-the-run crazy sheep dog. She is always bouncy, full of energy. If you don't have any dog at home, she is the one for u. She will adore u , mesmerize over u. Her puppy-like, couldn't-careless attitude sometimes annoys the more senior dogs which are dominant, grumpy older dogs. Very faithful and loyal to her owner. She needs an active lifestyle, where the owner can work with, and play with her, with a big space to run about around..
