I remember which one they are referring to. The picture looked like this:

The little boy was standing in front of some people (parents, presumably. this was a while ago and I can't remember if he had siblings or not.). He was about six or seven. He was holding a little white terrier-looking dog. The fireman came and ripped the pooch out of the boys arms and the boy had his arms outstretched and was screaming "Snowball! Snowball!". He was crying.

It made me cry so much for the little boy. He did get his dog back if I remember correctly.
