We recently brought my 1 year old GSD back inside she has lived inside before. After we brought her back inside she started having these energy spurs she'll run really fast around our kitchen and living room and down our hallway when she's doing this she also will jump on the furniture especially my bed and the couch in our den sometimes she'll just lay there until you come near her and then she'll act like she is going to rip into the couch and she'll take off running again. Sometimes she'll get infront of me and jump up and down like she wants to play with me and then take off running again. Most of the time it happens when I try to go to bed and I'll shut me and her in my room and she'll start rubbing up against my bed and then jump on it and when I try to grab her to get her off she just goes nuts and starts running around.
When she was little and she lived inside she would do this but I could easily calm her down. Now that she is bigger it is much harder. She knows she is not allowed on the furniture. She gets plenty of exercise at least 3 hours a day playing with her toys and a 2 mile walk in the evening.
Is there something that is causing her to do this? and if so is there anything I could do to correct this?
