The more people I meet, the more I love my dog. Every day I am reminded why I love him so much. Three weeks before Christmas in 2008 at about 2:00 in the morning, my dog woke us up out of a sound sleep because someone was knocking at our door. He barked in front of me as if to protect me from the stranger who was knocking. My husband answered, and it was a local police officer telling us that my father-in-law had called the police because he forgot our number. My mother-in-law was suffering from a brain disease and was in the hospital. We thanked the officer and raced to the hospital. We would have taken him, but the hospital would consider him to be a dirty pet. After visiting the hospital we drove home and hugged our dog once more. At this point it was unlikely that little dog remembered waking us up. What he did remember was that we left him alone for several hours and he missed us. He thought we missed him, too, so he greeted us at the door with his tail wagging  . Someone tried to break in our house that summer, but, once again, our little dog saved the day. Our curtains were damaged, but no one got in. When I got home from work, I found parts of my curtains lying on the floor. We called the police and the officer said that he did a great job. My dog is a loving sweet dog who just wants some attention. I worked with him for months and now he sits, dances, sings, shakes hands, and so much more. The best part is he looks out for me as much as I look out for him. My husband says the dog is spoiled  ; I say he finally has a loving home. The author's dog woke her up to tell her that   _  .
