I always try to choose a name that can be shortened to one syllable to make commands easier and clearer for the dog (and me). As an example, our current two labs are Reba and Gemini. Reba becomes "Rebe" in the field and Gemini becomes "Gem". Both allow emphasis for commands. That has made my life easier over the years. Multiple syllable names that sound weird or can't be shortened somehow just don't work for me.
I named my new Vizsla pup Goose. I always let my kids provide ideas for names and my oldest son really liked the name Goose. My wife and daughter couldn't come up with anything better and I am not particular, as long as it isn't too long of a name or too stupid.
Current dogs are named Abby and Belle....and now Goose.
There are sometimes two names for a dog: the name on its AKC registration which is traditionally three names like a person's name on a birth certificate. The other name is the dog's call name. I prefer one syllable call names: Sport, Butch, Gus, Mags, and Jen are examples. I've also thought that I would call my next dog either Girl or Boy which gets reinforced with "good boy" and "good girl." Brittanys were created in France, so Elle (el) for a female and Homme (home) for a male would work nicely.
