How to Tell If Your Dog Has Anxiety (Free Assessment Tool)

The 5 Most Reliable Signs of Dog Anxiety

Individual behaviors can have many explanations. But when you see two or more of these consistently, anxiety is the most likely cause.

1. Destructive behavior focused on exits

This is the most telling sign. An anxious dog does not chew random shoes — they scratch at the front door, gnaw on window frames, or dig at the threshold you walked through. The destruction is targeted at the barrier between them and you (or between them and escape). Exit-directed destruction is the hallmark sign that distinguishes separation anxiety from boredom [ASPCA] .

2. Excessive vocalization when alone

Barking, howling, or whining that starts within minutes of your departure and continues for extended periods. The key word is extended — a few minutes of barking after you leave is normal. An hour of non-stop howling is not. Setting up a camera or asking your neighbors can help you gauge the duration.

3. Panting, drooling, or trembling without physical cause

If your dog is panting heavily when the room is cool and they have not exercised, or drooling excessively in a non-food context, their body is in a stress response. Trembling during storms or fireworks is the most recognizable version, but some dogs tremble simply from being left alone.

4. Pacing in fixed patterns

Anxious dogs often walk the same route repeatedly — door to window to door, or in a circle. This repetitive motor behavior is a coping mechanism, similar to how some people pace when nervous. If you notice wear patterns in your carpet near doors, that is a strong signal.

5. Refusal to eat when alone

A food-motivated dog that ignores a stuffed Kong or leaves their breakfast untouched while you are away is telling you something important. Anxiety suppresses appetite. If your dog eats normally when you are home but ignores food when you leave, the stress response is overriding a basic drive.

Anxiety vs. Boredom vs. Medical Issue

Before assuming anxiety, rule out the alternatives:

• Boredom — destructive behavior is random (shoes, pillows, trash) rather than exit-focused. Dog eats normally. Behavior happens throughout the day, not just in the first 30 minutes of alone time.
• Medical issue — sudden behavior changes in an older dog, or behaviors accompanied by lethargy, vomiting, or changes in gait, warrant a vet visit. Pain can mimic anxiety symptoms.
• Under-exercise — a young, high-energy dog that gets 15 minutes of exercise a day will be destructive. That is not anxiety — it is unmet physical needs.

If you are still unsure, set up a camera. Record the first 30 minutes after you leave. What you see will tell you whether this is anxiety, boredom, or something else entirely.

Types of Dog Anxiety

Understanding the type helps you choose the right intervention:

• Separation anxiety — triggered by being left alone or separated from their primary person. The most common type, affecting 14-20% of dogs.
• Noise phobia — triggered by specific sounds: thunder, fireworks, construction, vacuum cleaners. Often develops or worsens with age.
• Travel anxiety — triggered by car rides, unfamiliar environments, or the vet's office.
• Generalized anxiety — persistent low-level nervousness without a clear trigger. The dog seems "on edge" most of the time. This is the hardest type to treat without professional help.

What to Do If Your Dog Scores Moderate or Higher

If our assessment tool shows moderate or severe anxiety, here is a practical starting plan:

1. Start with an anxiety vest. Pressure therapy works for 70-90% of dogs and provides immediate comfort with no side effects.
2. Add calming treats with L-theanine or chamomile. Give them 30 minutes before known triggers.
3. Build a consistent daily routine — feeding, walks, play, and departure/arrival rituals should happen at roughly the same time each day.
4. Begin graduated absence training if separation is the trigger.
5. See your vet if symptoms are severe or if 4-6 weeks of consistent intervention shows no improvement.
