Separation anxiety is one of the most common behavioral problems in dogs and one of the leading reasons dogs are surrendered to shelters. Understanding it is the first step toward helping your dog feel safe when you're away.
How Common Is It?
Studies estimate that 20–40% of dogs presented to veterinary behavioral specialists suffer from separation anxiety. A 2020 study in Applied Animal Behaviour Science found that the prevalence increased significantly during the COVID-19 pandemic, as dogs became accustomed to constant human presence and then struggled when owners returned to work.
Signs of Separation Anxiety
The hallmark behaviors include destructive chewing (often focused on doors, windows, or personal items with the owner's scent), excessive barking or howling, house soiling despite being house-trained, pacing, drooling, and escape attempts that can result in self-injury. These behaviors occur specifically when the dog is separated from their attachment figure and typically begin within 15–30 minutes of departure.
It's important to distinguish separation anxiety from boredom-related destruction or insufficient house training. A dog with separation anxiety shows distress signals (panting, drooling, pacing) as you prepare to leave and the behavior is triggered specifically by your absence, not by lack of stimulation.
Causes and Risk Factors
Separation anxiety is more common in dogs adopted from shelters (who may have experienced abandonment), dogs that have experienced a significant change in routine or living situation, and dogs that are hyper-attached to one person. Some breeds are more predisposed, though it can affect any dog. Contrary to popular belief, it's not caused by "spoiling" your dog — it's a genuine anxiety disorder.
Treatment: Desensitization
The gold standard treatment is systematic desensitization — gradually increasing the duration of absences while keeping the dog below their anxiety threshold. This typically starts with "mock departures" of just a few seconds, slowly building up. A 2014 review in the Journal of Veterinary Behavior confirmed that desensitization combined with counterconditioning (associating departure cues with positive things like special treats) is the most effective behavioral approach.
Environmental Management
While working on desensitization, management strategies help: providing puzzle toys (like frozen Kongs) during absences, creating a safe, comfortable space (many dogs do better in a room rather than a crate), playing calming music (research has shown classical music reduces stress behaviors in kenneled dogs), and minimizing dramatic departures and arrivals. Avoid punishing your dog for anxiety-related behavior — punishment increases fear and worsens the condition.
When Medication Helps
For moderate to severe cases, veterinary behaviorists may prescribe anti-anxiety medication (such as fluoxetine or clomipramine) alongside behavioral modification. These medications aren't a quick fix but can lower the baseline anxiety enough for behavioral therapy to be effective. The American College of Veterinary Behaviorists recommends medication as part of a comprehensive treatment plan, not as a standalone solution.
