Tips for Choosing the Right Name
✓ Themed names build a story
Theme names ('River', 'Atlas', 'Sage') give your dog a character that grows with them.
✓ 1–2 syllable names train best
Dogs learn shorter names faster — even within a theme, shorter wins.
✓ Test the name out loud
Say 'Come here, [name]!' 5 times fast. Does it feel natural at the park?
✓ Avoid command conflicts
Names that rhyme with 'No', 'Sit', 'Stay', or 'Down' create confusion.
