I took a cup of coffee with a friend and her black chiwawa. A little dog very nice and sociable as my friend. All of a sudden you approach this beautifull dog with a huge head..that without pleasantries approaches the chiwawa sniffing and than watching from above. As if wondering which country were so small that being. Often observe the dogs and their owners together. Often they are one the mirror of the other. Just in social behavior. You can imagine who was the big dog's owner
