Is a dog really man's bestfriend?

my dogs are certainly my best friends.they are so loyal they seem to know what mood im in.they always give me kisses and cuddles and if i go out will all sit at the window until they hear my engine.they seem to know my car even when im at bottom of road.i so love them to bits.i wrote a poem about my dogs.

i had some dogs which i can consider my best friends. they do not talk to me alright, but their loyalty and trustworthiness is beyond question. not all dogs have the same degree of loyalty. i know this for sure after having had so many dogs in my life. the good qualities in a dog does not come with its breed. it is inherent in a dog itself. we will just be lucky if we can get hold of one who has all the qualities of a good pet that we desire most. so far, in my adult life, i have had the honor of having four. as a child, there is only one that i can recall.
