Separation anxiety in dogs: how to recognize it and act
You come home and the cushion is in shreds, the neighbor says he howled for two hours, there is a puddle by the door. First thing to know: your dog is not taking revenge. Revenge requires an intention that does not exist in him. He had a bad time, and he shows it his way.
Second thing: not every dog who misbehaves alone is anxious. Boredom, lack of exercise, frustration at the window produce the same damage. Before talking about separation anxiety, you have to look, and the only reliable way is to film.
Boredom or distress: film first
Set your phone or a camera facing the door and the spot where he stays, and leave as usual. The first twenty minutes say it all. A bored dog rummages, chews a cushion, then lies down and sleeps. A dog in distress cries or howls continuously, paces, drools heavily, scratches the door or window, pants without effort, sometimes hurts himself trying to get out.
You can also run that film through Mimo for a body reading: stress panting, lip corners pulled back, eyes searching for the exit can be spotted even on a fixed shot.
The signs that point to anxiety
Vocalising starts within minutes of your departure and does not stop. Destruction is concentrated on exits, door, frame, window, and on your belongings that carry your scent. Accidents happen in an otherwise house-trained dog, often near the door. He does not eat what you leave him, even his favorite treat, and devours it when you return.
Even before you leave, the ritual winds him up: the keys, the shoes, the coat. He follows you from room to room, pants, trembles, presses against you. On your return, the greeting is frantic and long, well beyond the normal minute of joy.
Where it comes from
A puppy who never learned to stay alone, an adopted dog who has already been abandoned, a sudden change of rhythm (working from home then back to the office, a move, a break-up), a fear experienced alone (storm, alarm) that linked solitude with danger. Some very people-oriented breeds, like the Golden retriever or the Poodle, are more exposed.
It is not a training failure or a “spoiled” dog. It is an emotion, fear, in a situation he does not control. You treat it like a fear: by desensitizing gradually, never by confrontation.
The five-step plan
Five levers, worked in parallel, over several weeks.
- Neutral departures and returns. No long goodbyes, no fanfare welcome. You leave, you come back, you put your things down, and you say hello once he has settled.
- Defuse the ritual. Pick up your keys and sit down. Put on your coat and go to the kitchen. Departure cues must stop predicting departure.
- Graded absences. Start with thirty seconds behind the door, come back before he winds up. Then two minutes, five, fifteen. Move up a step only when the previous one is calm. Film to know.
- An occupation for departure. A long-lasting chew or a lick mat given just before you leave, and taken away when you return. Chewing lowers tension.
- A safe resting place and real exercise beforehand. A bed off the path, away from the window, and a sniffing walk rather than a run before you leave: a dog who has sniffed for twenty minutes sleeps better.
Count weeks, not days. During the working phase, avoid real long absences as much as possible: a neighbor, a dog sitter, daycare. Every panicked absence erases part of the progress.
What does not work
Punishing on return, even with a sharp “no”, is the worst choice: the dog does not connect the punishment to the mess from two hours ago, he connects your return to something unpleasant, and the anxiety grows. Getting a second dog “to keep him company” does not cure the fear of your absence: you may end up with two anxious dogs.
Anti-bark collars add pain or discomfort to fear. And letting the dog “get used to it” by leaving him eight hours straight is the opposite of desensitization: it is flooding, which fixes the fear instead of undoing it.
When to consult
If your dog hurts himself (broken claws, damaged gums), refuses all food when alone, if progress stalls after a few weeks, or if your life is turned upside down, consult. A veterinary behaviorist can rule out a medical cause, assess severity and, when needed, propose a treatment that lowers the anxiety while the behavioral work happens.
Medication is neither a failure nor a stand-alone solution: it lets the dog be in a state where he can learn. A positive-methods trainer then supports you through the plan, step by step.
Frequently asked questions
My dog only destroys things when I leave, not when I am there. Is it definitely anxiety?
Not necessarily. Many dogs get thoroughly bored alone and touch nothing in your presence because you keep them busy. Film: a dog who chews a cushion then sleeps is bored, a dog who cries for two hours at the door is in distress.
Should I leave the TV or radio on?
It can help mask building noises, but it does not treat the fear. Useful alongside graded absences, not instead of them.
How long can a dog stay alone?
A habituated adult tolerates four to six hours, a puppy much less. Beyond that, a break is needed: a walker, a neighbor, daycare. An anxious dog, however, does not tolerate a duration he has not learned, even a short one.
