I recently adopted a 6 year old mutt that was listed as a Bernese Mt / Border Collie mix, or a Rotti mix. She was abandoned, and has all the neurosis that might result, especially separation anxiety and inattentiveness. Today I visited the Sugarbrook Field Trail Wildlife Management Area with her. While she is still very much getting used to her new family, she seemed very happy to be outside and off leash, more attentive because she was free to roam a touch further, and most importantly, unafraid. This may become our regular hangout.
