Canine Anxiety: Causes, Consequences, and Treatment

Anxiety disorders are among the most common and serious welfare problems in companion dogs. Fear, separation distress, and generalised anxiety reduce quality of life chronically and are often inadequately addressed.

Key Facts

An estimated 40-50% of dogs show clinically significant anxiety symptoms
Noise phobia affects one third of dogs — thunderstorms and fireworks are major triggers
Separation anxiety is the second most common reason for dog relinquishment
Anxious dogs have shorter telomeres (a biological ageing marker) than calm dogs
Combination treatment (behaviour modification plus medication) outperforms either alone

Welfare Considerations

Anxiety is not a behaviour problem but a welfare state. An anxious dog experiences chronic psychological suffering — elevated cortisol, suppressed immune function, shortened life expectancy, and impaired quality of life. Punishment-based approaches to anxiety-driven behaviour worsen the underlying state. Evidence-based treatment combines behaviour modification (systematic desensitisation and counter-conditioning) with appropriate medication where indicated. Early identification and treatment produce substantially better outcomes than waiting until anxiety becomes severe.

What You Can Do

Seek veterinary behavioural assessment for any dog showing fear or avoidance behaviours
Use only force-free, reward-based approaches with anxious dogs
Discuss anxiolytic medication with a vet — it can be part of a welfare-positive plan
Provide safe spaces and predictable routines to reduce environmental anxiety triggers
Never punish a dog for anxiety-driven behaviour — it worsens the welfare state
