Animals helping animals.

Some animals actually help other animals. Stumpy the blood donor dog has actually saved 120 dogs with his donation.  
A vigilant alpaca protects turkeys  from foxes.  Trained dogs are helping save the red squirrels who are in danger of extinction.

All of the helpful animals look happy in their work. The alpaca looks delighted to be surrounded by turkeys. Some animals like some people  really do like to help.
These are the ones we have heard about. I winder how many other helpful animals  are out there.
