Our GSD is 2 years old. I am a stay at home mom, so GSD is very used to someone being home with her all the time. When we leave, she goes upstairs into all of our garbage cans (as she can reach the small ones in bedroom and bathrooms) and pulls stuff out. Is this just her way of letting us know she is annoyed or is this just her way of handling separation anxiety? Has anyone else experienced this type of behavior when you leave the house?
