Can Dogs Have Panic Attacks? Signs, Causes & What To Do

By Dr Duncan Houston

Quick Answer

Yes, dogs can have panic attacks. These are sudden, intense fear responses driven by a surge in stress hormones like adrenaline and cortisol. They are more severe than normal anxiety and can lead to dangerous behaviours if not managed early.

As a veterinarian, I see this most often in dogs with noise sensitivities, separation issues, or underlying medical or behavioural conditions.

What Is a Panic Attack in Dogs?

A panic attack is an acute activation of the fight or flight response.

When triggered, the body rapidly releases adrenaline and cortisol, causing:

• Increased heart rate

• Heightened alertness

• Urgent need to escape or hide

Unlike general anxiety, panic attacks:

• Start suddenly

• Escalate quickly

• Can occur without a clear trigger

Dogs are not “overreacting” in these moments. Their brain is telling them they are in danger.

Signs of a Panic Attack

Signs can vary but often include:

• Trembling or shaking

• Pacing or frantic movement

• Trying to escape or bolt

• Excessive barking, whining, or howling

• Drooling, vomiting, diarrhea, or urination

• Clinginess or hiding

• Destructive behaviour such as scratching doors or digging

In severe cases, dogs may injure themselves trying to escape.

Severity Levels

Understanding severity helps guide what to do next.

Mild

• Shaking, restlessness, clinginess

Moderate

• Vocalising, pacing, hiding, difficulty settling

Severe

• Escape attempts, destruction, self-injury, inability to settle

Severe cases require veterinary support.

Panic vs Anxiety vs Phobia

Anxiety
Ongoing, lower-level nervousness

Phobia
Intense fear linked to a specific trigger such as fireworks

Panic attack
Sudden, extreme fear that may occur with or without a trigger

Many dogs with panic attacks also have underlying anxiety or phobias.

Common Triggers

• Loud noises such as storms or fireworks

• Separation from owners

• Previous trauma or negative experiences

• Pain or illness

• Feeling trapped or confined

High-Risk Situations

Some situations predictably increase the risk of panic:

• Fireworks events or storms

• Moving house or environmental changes

• Boarding or kennels

• Changes in routine or owner absence

• Recovery from illness or injury

Planning ahead in these situations can prevent escalation.

Medical Conditions That Can Look Like Panic

Not all “panic” is behavioural.

Conditions that can mimic panic attacks include:

• Focal or partial seizures

• Pain, especially spinal or abdominal

• Cognitive dysfunction in older dogs

• Toxin exposure

• Neurological disease

If episodes are sudden, unusual, or worsening, always rule out medical causes first.

What To Do During a Panic Episode

Focus on reducing stimulation and creating safety.

1. Stay calm and avoid reacting emotionally

2. Move your dog to a quiet, low-stimulation area

3. Reduce noise where possible

4. Speak softly if they seek reassurance

5. Allow hiding rather than forcing interaction

Do not punish, restrain, or force exposure. This worsens fear.

When It’s an Emergency

Seek urgent veterinary care if you notice:

• Self-injury or bleeding

• Collapse or unresponsiveness

• Possible seizure activity

• Continuous panic lasting longer than 30 to 60 minutes

• Signs of toxin exposure

These situations require immediate attention.

Treatment Options

Behavioural Training

• Desensitisation to triggers

• Counter-conditioning to create positive associations

• Structured relaxation training such as mat training

Medication

Used when episodes are moderate to severe:

• SSRIs for long-term control

• Trazodone or gabapentin for situational use

• Fast-acting medications for predictable events

Environmental Management

• Consistent routine

• Safe, quiet resting areas

• Reducing exposure to known triggers

Supportive Aids

• Pheromone diffusers

• Nutraceuticals such as L-theanine or alpha-casozepine

Preventing Future Panic Attacks

• Track triggers, timing, and severity

• Intervene early before escalation

• Use medication proactively when prescribed

• Build confidence through gradual exposure

• Avoid overwhelming situations during recovery

Consistency is key.

Common Mistakes Owners Make

• Punishing fearful behaviour

• Forcing dogs into triggering situations

• Ignoring early warning signs

• Inconsistent routines

• Waiting too long to seek veterinary advice

These can worsen panic over time.

Practical Action Plan

If your dog has a panic episode:

1. Reduce noise and stimulation

2. Move them to a safe space

3. Stay calm and predictable

4. Monitor duration and severity

5. Seek veterinary advice if recurring

FAQs

Do dogs grow out of panic attacks?
No. Without intervention, they often persist or worsen.

Are panic attacks the same as seizures?
No, but they can look similar. A vet assessment is important.

How long does improvement take?
Many dogs improve within weeks to a few months with consistent management.

Should I comfort my dog during a panic attack?
Yes, if they seek it. Keep interactions calm and reassuring.

Final Thoughts

Panic attacks in dogs are real and can be severe, but they are also highly manageable with the right approach.

The key is early recognition, ruling out medical causes, and building a structured plan that supports both behaviour and physiology.

If your dog is showing signs of panic or sudden behavioural changes, tracking patterns and getting early advice can make a significant difference. The ASK A VET™ app allows you to monitor behaviour, identify triggers, and connect with a veterinarian when you need guidance.
