You can say any fool thing to a dog, and the dog will give you this look that says, :My God, you’re Right! I never would of thought of that!”
The association between dogs and humans stems from the fact that dogs perform functions that are useful to us. Some of these functions are quite utilitarian, others are more personal and psychological in nature. Some of the more common utilitarian functions include guarding and protecting property and people. eg. police work and war dog work, helping during hunting, finding game, pulling it down, digging it up, and retrieving it, shepherding, tending sheep, cattle, reindeer, and even geese or ducks, hauling, pulling carts or sleds, carrying packs, seeking and finding objects, people, or substances, tracking dogs, drug snigging dogs, gas-detecting dogs, truffle seeking dogs, performing rescue work, retrieving people from water or people buried in snow or wreckage, assisting the disabled, seeing eye dogs, hearing ear dogs, handicap assistance dogs.
