Determine what triggers the barking - doorbell, fence line, boredom, separation anxiety.
Ensure your dog gets adequate physical and mental exercise to prevent boredom barking.
Never reward barking with attention. Withhold rewards until quiet.
Interrupt and redirect barking with clear commands and treats for obeying.
Try citronella spray collars, high-frequency devices, or collars that vibrate at the first bark.
Teach the quiet command. Always reward silence and good behavior.
Rule out pain, cognitive decline, or anxiety as a cause. Consult your vet.
