I adopted Wolfgang as a 2 year old. He was underfed and a bit traumatized from having been dumped at the Humane Society due to his family having lost their home to foreclosure. The foster mom who took him from the Humane Society was a professional GSD trainer and hypothesized that Wolfgang was a grazing eater because he just picked at his food. He exhibited the same traits as Shadow when I got him home. He would grab a mouthful of food, follow me and drop it on the ground in the room I was in and eat it there. Rinse and Repeat. Gradually I found food he liked more and he more naturally wolfed down his food. The follow and drop eating behavior became sporadic over time as we bonded and he became sure of the permanence of his home. Shadow's behavior may well change over time just like Wolfgang's. Shadow sounds marvelous. Enjoy!
