The form of animal behavior that this prairie dog on guard duty exhibits is altruistic behavior.
This means that the dog isn't only thinking about itself, but rather about the others as well. Since it escaped danger, it alarmed other dogs as well, so that they could also be safe and not injured by the golden eagle. It seems that not only humans, but also animals are capable of showing such a behavior.

Explanation:
The body of an adult man weighing 70 kg is made up of approximately 6.7 • 10 ^ 27 atoms.
The body of an adult male contains approximately 57% water, but if we look by weight, hydrogen is only 11%, while if we look at the mutual ratio of atoms in water, there are a total of 67% hydrogen atoms. 
In this way, most of the weight (mass) of the human body comes from oxygen, but most of the atoms in the body are hydrogen.
