I'm so sorry to hear this, everyone was so caught up in this poor sick pup . This kind of thing really puts a sick feeling in your stomach.
On the other hand, I'm a little relieved there is no suffering pup. I really feel bad for the people who donated though, try to chalk it up to you tried to do a good thing for the pup. I'm curious as I'm sure others are, on how this info was found out to be was a scam.
