A curious question: why dogs? I mean can't cats or donkeys be trained for similar objectives?
As a lifelong cat person it doesn't feel right to me that a son of a b.i.t.c.h is selected over my son (my cat i.e.).
PS: the forum was eating up a word so I had to put in periods there so it stays. Somebody inform the forum what the mother of a dog is called.
Dogs are trained on reward method which means dogs does something good, u reward it with food, dog will do it again for reward. So first is that dogs are very easily trainable than other animals. they are eager to please always, this attitude makes them great animals for training.
secondly, the bite. the bite doesnt kill a man like bigger cats but gets the job done, like stopping a man from getting away.
thirdly, the nose. this nose saves lives. cats have a good nose too but arent too eager to please so difficult to train.This nose can sniff a sniper hidden in trees, sniff explosives, sniff drugs. some breeds do it better than others. once the dog gets scent of a human or material like cloth, it can start chasing on basis of its nose only.
fourthly, ears. Very responsive to environment and can detect noises and sounds that humans cant, cats can too but again not easily trainable.
fifth.size matters. Intimidating looks, menacing teeth , bigger size keeps burglars and unwanted people at bay.
sixth. loyalty. give it food. then beat the hell out of it. it will lick your feet again after a few minutes. keep repeating. the dog wont go away , ever.
seventh. pack sense. the dog is a pack animal like a wolf. it will give its own life to save another pack member or leader like human.it thinks of a human like a family member.
Thats all from top of my head right now
