Gizmo is back to his old self - YAY! He ate all his dinner last night and played as usual. It was so sad when he wasn't feeling well Tuesday night. He wanted to play the "look what I got - come and chase me" game and he could barely walk fast much less run but he tried. I was walking behind him very slowly for 2 rounds around the dining room table then he just kind of gave up. It was so sad, but last night he was running at full force and barked at a noise he heard. I have never been so happy to hear him bark as I was last night!
