My Max was really small, 2 lb 9 oz at 14 months, and he would bark to get the attention of the other dogs. But the cutest was when the dog food bowl or water bowl was empty, he would really let me have it. Standing on his back legs, just telling me off. He would also do that when he felt it was bedtime. He'd just come right up to me and let me know it was bedtime! I sure miss that.
