The family who rescued a dog had reason to be glad they did because the dog rescued their three year old son. The boy wandered off and the dog kept him warm until help arrived. http://www.dailymail.co.uk/news/article-...-home.html
Isn't it wonderful. It really goes to show that the good we do comes back to us. In this case quite directly since the dog they rescued, rescued their son.
I think very often, with rescue dogs, they form very strong bonds to their families, and will always stand by them, and give what they can. He definitely saved this little boy's life because of his love and loyalty.
