Does anyone have a chihuahua? The little smooth haired ones, especially the fawn and white, sure are cute and my wife wants a house dog again. A nearby animal shelter had a young female come up for adoption yesterday, but there were 4 people wanting her so they had a drawing and we didn't win. I've heard conflicting stories about them perhaps being hard to house break and sometimes being bad tempered, although the couple I've seen lately were certainly friendly. What's others' experience with them?
