I have the same problem with my little one. He follows me around EVERYWHERE i go. Even if i am in the shower, he is ready to come in. I did spray some water on him to make him realize that it is wet but he didn't even care...still wanted to come in and be with me. Even leaving him with my husband doesn't work. He also cries and barks when i leave for work. I don't know how long he barks for. I waited outside yesterday for 5 minutes and he was still barking. I think he doesn't even touch his food all day until i come home and stand in the kitchen...then he eats. He seems to be fine though when i come home. He is just really happy to see me... and ready to play and go for a walk.
Well...i still hope that he will "grow out" of it because i just got him last weekend.
