Separation Anxiety in Dogs: Understanding the Signs, Causes and Solutions

Coming home to a destroyed sofa, complaints from neighbours about barking, or finding that your dog has had a toilet accident indoors can be frustrating. But what if these behaviours aren't caused by boredom or a lack of training?

For some dogs, being left alone can trigger genuine fear, anxiety and distress.

Separation anxiety is more than simply missing their owner. It is an emotional and behavioural condition that can significantly affect a dog's wellbeing and everyday life.

What Is Separation Anxiety?

Separation anxiety is a condition in which a dog experiences significant distress when separated from their owner or another important attachment figure.

Dogs are naturally social animals, and forming strong relationships with people is completely normal. However, some dogs struggle to cope when those people are no longer present.

It is important to understand that separation anxiety is not disobedience, stubbornness or attention-seeking behaviour.

A dog experiencing separation anxiety isn't deliberately destroying furniture or barking to annoy their owner. These behaviours may be expressions of genuine emotional distress.

You may also hear the term separation-related problems, which describes a wider range of behaviours occurring when dogs are left alone. Not all of these behaviours are caused by anxiety. Some dogs may struggle with frustration, environmental triggers or other underlying issues.

Identifying the cause is therefore an important part of any behavioural assessment.

What Causes Separation Anxiety?

There isn't always one clear reason why a dog develops separation anxiety. In many cases, several factors contribute to the problem.

Some possible influences include:

• Genetics and temperament: Some dogs may be naturally more sensitive or vulnerable to anxiety.

• Changes in routine: Moving house, changes in working hours or suddenly spending more time alone can be difficult for some dogs.

• Previous experiences: Rehoming, abandonment or frightening experiences may contribute to anxiety in certain individuals.

• Lack of gradual alone-time training: Dogs who haven't had opportunities to develop confidence being alone may struggle when suddenly left for longer periods.

• Medical conditions: Pain, illness, age-related changes or cognitive dysfunction can contribute to changes in behaviour.

• Environmental changes: A new baby, family member leaving, or changes in the household can sometimes influence a dog's sense of security.

However, not every rescue dog develops separation anxiety, and not every dog who follows their owner around the house has a problem.

Every dog is an individual.

Recognising the Signs of Separation Anxiety

One of the challenges with separation anxiety is that many behaviours happen when the owner isn't home.

Some dogs show very obvious signs of distress, while others experience anxiety much more quietly.

Common signs include:

Excessive barking or howling

Some dogs vocalise repeatedly or continuously when left alone. This may begin immediately after the owner leaves or develop shortly afterwards.

Destructive behaviour

Chewing doors, scratching walls, damaging furniture or attempting to escape can sometimes be associated with separation distress, particularly when the behaviour is concentrated around exits.

Toileting indoors

A previously house-trained dog may urinate or defecate indoors when left alone. However, medical causes and toilet-training difficulties should always be considered.

Pacing and restlessness

Some dogs repeatedly walk between rooms, circle, or remain close to the front door.

Panting, trembling or excessive salivation

These can be physical signs of stress, especially when the dog isn't hot or physically active.

Difficulty settling

Some dogs remain alert throughout the owner's absence, unable to relax or sleep.

Changes in behaviour before departure

Dogs are very good at recognising routines. Picking up keys, putting on shoes or preparing a bag can become signals that their owner is about to leave.

For some dogs, anxiety begins before the door even closes.

Are There Different Stages of Separation Anxiety?

Separation anxiety doesn't have one universally recognised system of stages. However, we can describe the severity of a dog's distress to help owners understand the problem.

Mild Separation-Related Distress

The dog may show early signs of discomfort, such as following the owner closely, becoming restless during departure routines, or briefly vocalising.

Some dogs may still be able to settle after a short period.

Moderate Separation-Related Distress

The dog may struggle to settle, bark repeatedly, pace, or show increasing anxiety when left alone.

The behaviour may continue for a significant part of the owner's absence.

Severe Separation Anxiety

Dogs experiencing severe distress may panic, attempt to escape, injure themselves, vocalise continuously or show significant physical signs of anxiety.

These dogs may struggle even with very short separations.

These categories are only general descriptions, not a formal diagnosis. The severity of separation anxiety should be assessed individually, considering both the dog's behaviour and emotional state.

What Happens in the Brain?

From a neurobiological perspective, separation anxiety involves the brain's response to a perceived threat.

When a dog experiences fear or distress, brain regions involved in processing emotions, including the amygdala, help activate the body's stress response.

This can involve the sympathetic nervous system and the hypothalamic-pituitary-adrenal (HPA) axis, which regulates stress hormones such as cortisol.

These systems are normal and necessary for survival. However, when a dog repeatedly experiences intense distress during separation, their emotional wellbeing can be affected.

A dog in a highly anxious state may find it difficult to relax, concentrate or learn new behaviours.

This is one reason why simply leaving an anxious dog alone until they stop barking isn't an appropriate treatment.

Our goal isn't to teach the dog to stop expressing distress. Our goal is to help them feel safe when alone.

Can Separation Anxiety Be Treated?

Yes. Many dogs can make significant progress with an appropriate behaviour modification programme, although treatment may take time and outcomes vary.

The first step is identifying whether the dog is experiencing separation anxiety or another separation-related problem.

Treatment may involve:

Gradual desensitisation

Helping the dog become comfortable with carefully planned periods of separation, starting at a level they can manage without significant distress.

Changing emotional associations

Creating positive, predictable experiences around relevant situations, while ensuring the dog isn't pushed beyond their coping ability.

Environmental management

Adjusting routines and arranging appropriate care to reduce repeated episodes of distress during treatment.

Building confidence and independence

Supporting the dog in developing comfortable, relaxed behaviours without forcing separation.

Veterinary support

In some cases, particularly when anxiety is severe, veterinary assessment and medication may form an important part of a treatment plan alongside behaviour modification.

Can Separation Anxiety Be Prevented?

Although we cannot prevent every case, especially where genetics, health or previous experiences contribute, there are ways to support healthy independence from puppyhood.

I recommend introducing short, positive periods of alone time gradually, while ensuring puppies have opportunities for appropriate social interaction, rest and security.

Other helpful habits include:

• Creating a comfortable, predictable resting environment.

• Encouraging calm, independent activities without forcing isolation.

• Gradually introducing normal departure routines.

• Avoiding sudden increases in the amount of time a puppy is left alone.

• Paying attention to early signs of distress.

• Maintaining an appropriate balance between companionship, enrichment and rest.

Remember, allowing a puppy to sleep near you or offering comfort doesn't automatically cause separation anxiety.

Dogs can have strong, healthy attachments to their owners while also learning to feel comfortable spending time alone.
