Wow that would be good for those cold chihuahua dogs. I remember when I first saw a chihuahua. I was swinging in the park and one came up to me. It was the weirdest thing I ever saw. It was bloated looking and shaking. I felt sorry for it and wanted to help it not be cold but didn't want to touch it because I didn't know what kind of animal it was. So I went and got my mother and she laughed at me and told me that it was a chihuahua dog that was pregnant. She couldn't believe that I had never saw one before. Now I see them everywhere.
