Evaluating a humane alternative to the bark collar: Automated differential reinforcement of not barking in a home-alone setting

Five family dogs barked too much when left home alone. The team set a small camera and a treat dispenser on a shelf. Every 30 seconds of quiet earned a beep and a piece of kibble.

The owners left for 30-minute sessions. Barking was counted live. The rule flipped on and off in an ABAB design so the team could see if the treat schedule really worked.

Three dogs almost stopped barking. Their quiet time jumped from a large share to over a large share. Two dogs still barked a lot, so the trick did not work for everyone.

When the treats stopped, barking came back. When treats returned, quiet returned. Thinning to every 2 minutes kept the peace, so owners would not need to feed every half-minute forever.

Jessel et al. (2016) reviewed many DRO studies the same year. Their paper says DRO works, and the dog data add a new home-alone example to that list.

Kimball et al. (2023) warn that lean schedules can bring back problem behavior when places change. The dogs also showed a small bounce when the schedule thinned, so plan for relapse.

Shawler et al. (2020) stopped vocal stereotypy with RIRD, not treats. For loud dogs, rewarding quiet worked without any scolding or interruption.

You can cut home-alone barking without shock collars. A $100 treat dispenser and a DRO rule give owners a humane plan. Start with 30-second quiet windows, then stretch the time. If barking returns, check the schedule first.
