What is separation anxiety?
Separation anxiety is a genuine anxiety disorder. When a dog with this condition is separated from the person they are attached to, they experience a physiological stress response — elevated cortisol, increased heart rate, and psychological distress. The destructive behaviour, barking, or accidents that result are not the dog acting out. They are symptoms of that distress.
This distinction matters because it changes the treatment approach entirely. Punishment after the fact — the classic mistake of returning home to damage and scolding the dog — has no effect on the behaviour and may worsen anxiety.
Signs of separation anxiety
The defining characteristic is that the behaviour occurs specifically in your absence. Signs include:
- Excessive vocalisation (barking, whining, howling) that begins soon after you leave
- Destructive behaviour — often focused on exit points like doors and windows
- Toileting indoors in a housetrained dog
- Drooling, panting, pacing, or self-harm
- Refusing to eat when alone
- Attempting to escape confinement
A home camera or video doorbell can be invaluable for seeing what actually happens after you leave — many owners are surprised by what they find.
What causes separation anxiety?
The causes are not fully understood, but risk factors include:
- A sudden change in routine (return to office after remote working, a bereavement)
- Early weaning or inadequate socialisation
- Previous rehoming or traumatic experiences
- Certain breeds with high social needs
- A previous period of illness or pain
What actually helps
Separation anxiety requires a systematic behaviour modification programme. The core approach is graduated absence training:
- Identify the threshold at which your dog begins to show stress (this may be 30 seconds or 30 minutes)
- Begin practising absences that remain below that threshold
- Gradually, over days or weeks, extend the duration
- Never leave the dog for longer than they can currently cope with during the training period
This process requires time and commitment. For moderate to severe cases, working with a qualified behaviourist is strongly recommended. Your vet can also discuss whether medication to reduce the anxiety baseline is appropriate — medication alone is not a solution, but it can make behaviour modification significantly more effective.
Common approaches that do not work
- Getting a second dog (the anxiety is about you, not about being alone)
- Punishing upon return
- Ignoring the dog before leaving to ‘reduce attachment’ (no evidence this helps)
- Expecting the dog to ‘grow out of it’
