I lost my Chihuahua last month. He is 3 years old and is not fixed. He's a tiny Chi....about 7 pounds. I live north of Detroit though, so I can't imagine it would be him. Still, the description sounds exact. I have pictures of him that I can send you. Even if it's not him, I would feel better knowing one way or another.
