I have a 1 year 3 month German shepered she was a hyper little thing had so much life and wild and a couple a days now my husband and I have notice she is more layer back wants more of our attention and is more attentive to what we are doing. We don't know if there is something is wrong or not as one had this problem or what it could be. We also have a 2 year old Great Dane as well and they are inseparable. They are both female as well Great Dane is spayed and German shepherd is not.
