The name is the most used cue you will ever teach. Pick one that is easy to say fast and easy for the dog to hear.
Sound
Two syllables ending in a vowel carry well: Maple, Juno, Piper. Hard consonants at the start cut through noise. Avoid names that rhyme with cues, like Beau and no, or Kit and sit.
Teaching it
Say the name once, and the instant the puppy looks, pay. Ten times a day for a week. Never use the name for anything the puppy dislikes.
Changing a rescue's name
Fine at any age. Pair the new name with the old for a week, then drop the old one. Dogs learn a new name in days when it predicts good things.
