Widely known for its implacable ferocity ...
The DOG (Canis Over-familiaris) is the product of millenia of evolution : capable of incredible feats !
Note how this dog - previously "conserving energy" - has snapped to instant situational awareness :
Stimulated by a faint rustling sound from inside the house, the Dog prepares to intercept a perceived threat against its family !
Racing inside, the Dog leaps to the defense of a young man sitting at the table. Will he be able to intercept the crackers in time ? (One can only hope so-for they contain materials Dogs believe are better suited for Canine consumption !)
Another job well done !!
Deciding to take no further chances on Human consumption of preferred Canine comestibles, the Dog takes up station to guard the kitchen against intruders.
Lord, what marvelous creatures Dogs are !!!
