Popular names that many people call their tiny male dog are Stan, Ben and Maxi. These names are popular because they do not give the dog a rough looking sound or image. Like other male breeds of dogs there is two ways to choose the name for the dog.
The first can be to simply choose a name which you like and think that the dog will like or the other option is to pick a name that is suited for the breed of the dog and the size. When this is done people choose a name which is focussed around the main details of the dog.
The tiny breed of male dogs tends to get called short names. This is not because it reflects on the size of the dog but more along the easy to remember side. When choosing a name there are many books which can be helpful.
