I just found this lovely picture on the Internet and thought I will share it with you.
It shows a female dog feeding a 10-day-old tiger cub and her puppy at a zoo in Hefei, Anhui province, China. The tigress, who is a first time mother, was deemed incapable of feeding her young because of insufficient milk (Picture by JIANAN YU/REUTERS).
The dog clearly adopted this little tiger cub and it's treating it as his own. It shows that animals are capable of altruism and they can be very kind to one another.
