Stress and anxiety in dogs can lead to noticeable changes in behavior and health, leaving owners worried about their pet’s well-being.
From pacing and whining to destructive chewing, these signs can be distressing for both you and your dog.
We outline the common causes of stress and anxiety in dogs, what you can do at home, and when to seek veterinary help.
Dog Stress and Anxiety — Why It Happens
Dogs experience stress and anxiety for many different reasons, ranging from environmental changes to underlying medical conditions. Separation from their owner, loud noises, unfamiliar people or animals, and traumatic experiences can all trigger anxious behaviors.
In some cases, chronic pain, illness, or hormonal imbalances may contribute. Emotional distress can manifest in subtle ways at first, eventually impacting a dog’s physical health if not addressed.

Common Causes of Stress and Anxiety in Dogs
Separation Anxiety
Separation anxiety occurs when a dog becomes highly distressed in the absence of their owner.
This can lead to pacing, whining, barking, and destructive behavior. Over time, repeated stress episodes may cause gastrointestinal upset, appetite loss, or depression.

Noise Phobias
Thunderstorms, fireworks, and other loud or sudden sounds can trigger intense fear in dogs.
Signs may include trembling, hiding, or attempts to escape. In severe cases, the stress can be so overwhelming that it affects heart rate, digestion, and overall health.
Changes in Environment
Moving to a new home, adding a new family member, or rearranging furniture can unsettle a dog.
They may pace, vocalize, or cling more to their owners. Dogs thrive on routine, and unexpected changes can cause ongoing anxiety.
Lack of Socialization
Dogs who haven’t been exposed to various people, places, and other animals early in life may be more prone to anxiety.
Encounters with unfamiliar situations can leave them fearful, leading to defensive behavior or withdrawal.
Chronic Pain or Illness
Physical discomfort can heighten stress and make a dog more reactive to minor triggers.
Conditions like arthritis, dental pain, or skin problems may lead to irritability, restlessness, or changes in behavior. Addressing the root health issue is key to improving emotional well-being.
Past Trauma
Rescue dogs or those who have been abused may carry emotional scars that lead to chronic anxiety.
Certain triggers may remind them of past experiences, resulting in fear-based behaviors that require patient, gentle handling.
What to Do If Your Dog Is Experiencing Stress and Anxiety
Begin by identifying and reducing the source of stress wherever possible. Provide a calm, safe space where your dog can retreat when feeling overwhelmed.
Consistent routines, regular exercise, and mental stimulation can help reduce anxiety.
Using positive reinforcement training builds confidence and creates positive associations with previously stressful situations.
In some cases, calming aids such as pheromone diffusers, pressure wraps, or prescribed medications from your vet may be beneficial. Always avoid punishment, as it can increase fear and worsen anxiety.
When to Call or Visit Your Vet
If your dog’s anxiety is severe, persistent, or interfering with daily life, it’s time to seek veterinary guidance.
Sudden changes in behavior, especially when accompanied by physical symptoms such as vomiting, diarrhea, or loss of appetite, may indicate an underlying health issue.
Dogs that become aggressive, self-mutilate, or show signs of extreme distress during specific events need prompt evaluation.
Your veterinarian can recommend a tailored treatment plan, which may include behavior modification, supplements, or medication.
