Thought maybe I'll take Charlie for a short walk to the end of the block from home. Ended up a pretty long one in terms of timing. He spotted a gopher in the ground. At first I let him just watch, but he would not leave! Sat his butt down and pulled his new head collar. I wish I had the camera with me. I ended up carry him all the way back home, all 22lb of him! By the way, the new head collar works very well, except the pulling when he saw the gopher. He is much better on leash now.
