I think many people got emotional because they could picture their own dogs being lost, and would want whoever found them to do everything in their power to find the true owner. It really wasn't even from your post, but it seemed like people were offering to take the dog, before you even had a chance to find the owner, and I think this got people upset.
Yorkietalkers often get suspicious when someone doesn't do what they consider is enough updates, but we have a wide variety of people, and a really good system of checks and balances. I just want to welcome you to Yorkietalk, and try to focus on the many good points, I'm so glad there are people like you that will care for a lost dog. So many others would have just shut the door. Anyway, welcome to Yorkietalk, we're not perfect, but we are darn good!
