Well, I think it was SOOOOO weird that I even found that! I was reading another post where the poster was asking if her Chi was long or short haired (I still don't know) so I decided to go to Google and look up "Chihuahua puppies" and I clicked 'images'. The forth pic was of the two in the picture you posted and I remember thinking "aw, those two are cute" and I searched around a bit more. Then I came back here to look at pics and I saw your post and I"ll be darn if it wasn't the exact same picture! How coincidental is that?? I'd say the chances of something like that ever happening again are VERY slim.
Well, I hope I saved you some money and heartache. If you lived by me I could get you a pup and I would even bring it to your house. I'd even leave it in a beautiful little basket with a bow around it's neck with a note on it and ring the bell and run if you wanted me to :wink: !
Good luck finding your baby. There is one out there for you and it will come to you, I just know it.
