Vocal by design
Alert heritage - announcing things IS the historic job.
What helps: ['Thank-and-redirect: acknowledge the alert, cue quiet, pay the quiet', 'Manage triggers: window film and white noise beat willpower', 'Exercise first - a tired alarm system fires less. Never bark collars']

Prey drive is hardwired
Small fast animals flip an ancient switch - this is wiring, not disobedience.
What helps: ['Management IS the training: never unsupervised with small pets, period', 'Secure fencing plus leash or long line outdoors for life', 'Feed the drive legally: flirt pole and lure-chase games']

Selective about dog friends
Not every dog wants a hundred friends - this breed prefers a curated list.
What helps: ['Quality over quantity: a few calm, known companions beat any dog park', 'Parallel walks are the gold-standard introduction', 'Advocate for their space - declining strange dogs is good ownership']
