The short answer: First find out whether your dog is bored or anxious. Bored dogs do well with exercise before you leave, a long-lasting chew or puzzle, and background noise. Anxious dogs need slow practice with very short absences, and often help from a vet. Record your dog once to see which it is.

Boredom or separation anxiety?

The American Kennel Club recommends a pet camera or a barking monitor app to see what's going on, including whether a squirrel at the window is the real trigger.

If your dog is bored

  1. Exercise first. A good walk or game before you go. The AKC suggests a midday dog walker for long workdays.
  2. Leave a job. A stuffed, frozen chew toy or a treat puzzle given as you leave.
  3. Cover the noise. A radio, TV or fan masks the sounds that set off alert barking.
  4. Block the window if your dog barks at people outside.

If your dog is anxious

  1. Talk to your vet. For severe anxiety, a vet may prescribe medication to use alongside training, then phase it out.
  2. Practice tiny absences. Step out for a few seconds, come back, and reward calm behavior. Build up slowly. The AKC notes that adding too much time at once won't work.
  3. Make departures boring. Keep comings and goings low-key so leaving isn't a big event.
  4. Avoid long absences while you train if you can. A sitter, daycare or a friend can help.
  5. Never punish. Your dog isn't being spiteful. It's distressed, and punishment adds stress.

If progress stalls, a certified separation anxiety trainer or veterinary behaviorist can help. Some online vet services can also discuss anxiety treatment with you.

Common questions

How do I know if my dog has separation anxiety?

Signs include barking or howling that starts soon after you leave, plus pacing, drooling, panting, chewing doors or windows, or accidents only when alone. A pet camera can show you what happens. Your vet can confirm it and rule out other causes.

Will getting a second dog stop the barking?

Sometimes, if your dog is bored or lonely. But dogs with true separation anxiety are usually attached to their people, so a second dog often doesn't help. Try training first.

Is crating a dog that barks when alone a good idea?

Only if your dog is already relaxed in a crate. A crate can make a panicked dog more distressed and can lead to injuries.

Want a step-by-step plan instead of piecing tips together?

Brain Training for Dogs is an online course by certified trainer Adrienne Farricelli (CPDT-KA). It uses reward-based games to build focus and self-control, which is what most barking problems come down to. It costs about $47, one time.
