Dogs are smallthat have been kept by man for over 14,000 years. They are often called "man's best friend." The dog was very handy for man in the olden times. They were widely kept for working and hunting, but now they are mostly kept as a home pet.
Tamed dogs got their wightly ways from their wolf, who would have been wild pack hunters with many handy kinds of body speech. These kinds of inborn wits make dogs good at their playfulness and skills to fit into households, and these knacks have given dogs a friendly bond with men that has let them become one of the most wights on Earth today.
