Via Reid Stott, this photograph, from which I'll just quote the caption:

Rea, a police dog, helps rear two tiger cubs along with her own puppies in the Belgrade's Zoo, Friday, Jan. 4, 2002, as its trainer Mirko Matic watches. Rea adopted the little tigers after their mother tried to eat them. Serbia's police transferred Rea to the Belgrade's Zoo to feed the little tigers. As a sign of gratitude Zoo's management decided that one of tigers will be named SAJ which stands for Special Anti-terrorist Units - Serbian police crack squad. (AP Photo/Darko Vojinovic)

Seems like the humans in that part of the world could learn a little from the dogs. (And perhaps the tigers have learned a bit too much from the humans).
