oh boy i dont miss that time. Mental stimulation would entain training. Make her work for EVERYTHING she gets and does. Physical would be walks, off leash play time preferably in a fenced area but NOT at a dog park. As mentioned already, dog parks are bad news and horrible for socialization purposes. Get into a training class. Perhaps get her into agility after she's got some training. Its mental and physical exercise and fun for both of you. I understand the GSD/BC cross. our 7 year old male is one. He was an energetic pain in the butt until he was about 5.... lol. He's still got some energy but I think the GSD side of him has mellowed him out. He takes after the GSD side more than the BC side but both are high energy and high need for mental and physical activities. Its never too late to start training and working with her. Again, i highly encourage you to get into an obedience class with her and move through the different levels. It will help you bond with her and a trainer can also help you with ideas and training to help teach her to control the energy. Good luck!!!
oh and as for keeping her calm in the house, there are several things you can do. When you allow her back inside from a potty break or play time, bring her in leashed. Walk her around the house on the leash, If she begins getting too excited, remove her from the house and try again. you would do this a couple times a day. Give her a "place" out of the way of general traffic and tether her to a heavy table or chair with an appropriate chew toy to chew on. Praise her when she is calm. No rough play in the house. By giving her a place out of the general traffic area of the livingroom but she can still see whats going on, you can encourage her to remain calm inside and this allows her to get used to the activity without feeling its necessary to jump up at every single thing that happens. You would work up to her staying on her place off the leash and continue to praise her as though she were tethered. She'll connect the dots and realize that calm in the house is going to prove a greater reward than being jumpy and exciteable
