Things to consider when naming your dog:

A) Keep the name short, preferably one or two syllables. This will be easier for your dog to learn and remember. 
 
B) Match the name to your dog's personality. A noble hound may be fit to be King; a timid pooch may solicit the name Fluffy. 
 
C) Possibly name your dog the honor of being named after your favorite food: Brownie, Sugar, Cream Puff. 
 
D) Use a your sense of humor. Name your happy Lab, Spike, or a growling bulldog Cuddles, or your Great Dane Tiny. 
 
E) Be creative: Take your dog's name from the title of your favorite book, your current or a past lover, the name of your favorite actor, a line from your favorite song, the street where you grew up.
