Dog PTSD: Post-Traumatic Stress in Companion and Working Dogs

Dogs can experience post-traumatic stress disorder following severe or repeated trauma, with symptoms including hypervigilance, avoidance, and chronic fear responses.

Key Facts

Canine PTSD was formally recognised in military working dogs following research on dogs deployed in Iraq and Afghanistan
Symptoms include persistent startle responses, sleep disturbance, avoidance of triggers, and changed social behaviour
Rescue dogs with histories of abuse or neglect frequently show PTSD-like presentations
The neurological basis is similar to human PTSD, involving dysregulation of the fear memory circuit
Treatment combines behaviour therapy (systematic desensitisation and counter-conditioning) with medication in severe cases
SSRIs and trazodone are commonly prescribed for dogs with severe anxiety and trauma responses
Early intervention following traumatic events significantly improves prognosis
Some working dog programmes now include psychological rehabilitation before rehoming retired dogs

Welfare Considerations

Canine PTSD represents a significant animal welfare issue that is often underdiagnosed. Many dogs from rescue backgrounds are euthanased due to behaviour problems that are in fact trauma responses. Recognition of PTSD as a genuine clinical condition - not just 'bad behaviour' - changes the treatment approach fundamentally. With appropriate behavioural and pharmacological support, many dogs can recover substantially. Investment in trauma-informed rescue and rehabilitation is both welfare-positive and cost-effective.

What You Can Do

If adopting a rescue dog, ask about their history and seek a behaviourist experienced in trauma recovery
Work with a certified clinical animal behaviourist if your dog shows persistent fear or avoidance
Avoid punishment-based training which can worsen trauma responses
Support rescue organisations that provide proper behavioural rehabilitation before rehoming
Advocate for pre-rehoming assessment and trauma support for all rescue dogs
