Dog - Wikipedia, the free encyclopedia |
 | | In this time, the dog has developed into hundreds of breeds with a great degree of variation. |
 | | For example, heights at the withers range from just a few inches (such as the Chihuahua) to roughly three feet (such as the Irish Wolfhound), and colours range from white to fl, with reds, greys (usually called blue), and browns occurring in a tremendous variation of patterns. |
 | | Dogs, like humans, are highly social animals and this similarity in their overall behavioral pattern accounts for their trainability, playfulness, and ability to fit into human households and social situations. |
