Wow! Thank you everyone for your rapid responses. I did not mean to portray I only want or were after a "Tiny" in particular. We just love the breed period, and want a loving lil' cuddly.
Obviously though, we were more attracted to getting the smallest we could - for our own reasoning. Sounds as if it is just a chance one takes (disease wise) and pray that all will be well. Think all the so called "horror stories" were getting a bit overwhelming for me is all. Again, I greatly appreciate the encouragement and positive responses.
