If you don't want to name your poodle something "fru-fru" try using a name that goes with the color of their fur. For instance, if they're black, try something like Smokey or Coal. If they're white, try Blizzard or Sugar.
You should pick a name based on the dog's personality. Poodles are well known as been French, so maybe you should pick a french name like Pierre or Fifi. Poodles were also popular in the 1950s with the poodle skirt in style, so picking a name popular then would work.
