The deceased dog is NOT the issue. A child LAYING DOWN in the road is the issue. That child could have easily BEEN HIT NEXT. What do I do? Put my hands on someone else's child and attempt to "rescue" ? 

Kids are TAUGHT NOT TO TALK TO STRANGERS, and taught THEY CAN ALWAYS HAVE THE POLICE TO HELP THEM. 

If I saw a stranger attempting to pick up, carry or separate a dog - which any child would be screaming, crying, shouting and visibly UPSET how would that look? Would you assume a kind stranger is trying to rescue a child whose dog was just involved in a hit and run? Especially a deaf child? I don't know sign language. 

That child could have been MORE frightened and what if he ran out into traffic or got hit trying to get away from me? 

We call 911 for emergencies. This qualifies as an emergency. I'm not calling 911 because McDonalds didn't get my order right. 

BTW Peggy was being respectful to you in her comments and for you to be rude was uncalled for. You asked, she answered.
