I have three dogs, two are pets and one is a livestock guard dog
I have a miniature pinscher myself, I really love him. I can definitely understand why people call dogs "man's best friend", we really have a special relationship with them.
They are so smart and territorial as far as protecting the home too
Not only that, they can perform so many other roles too, like hunting, herding, and even aiding handicapping individuals as well.
Yes my livestock guard dog protects the livestock and can not be lured off the job even with a treat
That's impressive self control, I've heard the ability of livestock dogs to guard their herd is instinctive, since they're bonded to the herd at an early age.
Dogs also helped the handicapped to be able to retain some independece as well
That's very true, they can even assist police and military too due to their great sense of smell, helps with bombs and drugs.
Dogs truly are mans best friend they not only help us they actually love us as well
It makes sense that dogs were the first species to be domesticated, if they didn't have such a good innate relationship with humans it wouldn't have been possible I'm sure.
