Why some dogs bark, howl or chew when left alone
The door closes, and within a minute the howling starts. Or you come home to a scratched door frame and a note from a neighbor. It’s easy to take it personally. It isn’t personal.
The ASPCA is clear on this point: dogs who bark, howl, chew or have accidents when left alone aren’t being spiteful or disobedient. They’re showing distress. That changes what helps.
What it usually looks like
The same handful of behaviors show up again and again, usually soon after the owner leaves:
- Barking or howling that keeps going
- Chewing or scratching at doors, door frames and windowsills
- Pacing the same path back and forth
- Accidents from a dog who is otherwise house-trained
- Drooling or heavy panting
Many dogs also start to react before you leave. Picking up keys, putting on shoes or grabbing a bag can be enough. We cover those in departure cues.
Rule out a medical cause first
Some of these behaviors have medical causes. The ASPCA lists house-soiling causes such as incontinence, urinary tract infections and medication side effects as things to rule out. A vet visit comes first, before any training plan. It’s also the right place to ask whether anything else is going on. Only a vet can diagnose your dog.
Why punishment backfires
If the behavior comes from distress, punishing it adds more distress. A dog who is scolded for a chewed door when you get home can’t link the scolding to something that happened hours earlier. What they can learn is that your return is unpredictable, which makes the next absence harder.
What does help
The approach the ASPCA describes is gradual: short absences your dog can handle calmly, built up slowly.
- Start below your dog’s limit. If trouble starts at five minutes, practise absences well under that.
- Watch, don’t guess. A phone or pet camera shows you what actually happens while you’re out.
- Grow the time in small steps. Go a little longer after calm reps, repeat after mild signs, and step back after a stressed session.
- Avoid long absences while you train. One long day can undo weeks of progress, so line up cover. See covering long days.
We explain the method in more detail in graduated departures.
When it’s more than a training problem
Stop and call your vet if your dog injures their mouth or paws, breaks teeth or nails, or tries to get through windows or doors. That needs a professional. Ask your vet about a board-certified veterinary behaviorist (DACVB) or a Certified Applied Animal Behaviorist. More on that in when to call your vet.
