This is another classic name that dog owners tend to favor. A dog named Duke will follow commands very well, as he is intelligent, quick-witted, and has good manners. This is the same dog that is considered a true friend of man. Of course, you can always go with “Duchess” if your pet is a female.
“Duke” seems an especially popular dog name for larger breeds known for being loyal, like Labrador retrievers. However, it also works well for any smaller breed with regal qualities, such as a Yorkshire terrier.
