You’ve noticed it for a while. The barking when you leave. The chewed cushion when you get home. The way your dog follows you from room to room like a shadow.

You told yourself it was just a phase. But lately, it feels like it’s getting worse — not better.

Dog separation anxiety is a progressive condition. Left unaddressed, it escalates. What starts as mild whining can become destructive behaviour, self-harm, and severe distress that affects your dog’s health and your household. The earlier you recognise the warning signs, the easier it is to turn things around.

Here are the 11 warning signs that your dog’s separation anxiety is getting worse — and what to do about each one.

What Is Separation Anxiety in Dogs?

Separation anxiety is a genuine anxiety disorder — not disobedience, not spite, and not a training failure. It occurs when a dog becomes severely distressed in the absence of their owner or primary attachment figure. The distress is real, the suffering is real, and it requires a real response.

An estimated 14–17% of dogs experience separation anxiety significant enough to affect their quality of life. Many more show milder symptoms that owners dismiss — until those symptoms escalate.

11 Warning Signs Your Dog’s Separation Anxiety Is Getting Worse

1. The Barking or Howling Starts Sooner After You Leave

Early-stage separation anxiety often involves barking that starts a few minutes after you leave. As anxiety worsens, the barking begins the moment you pick up your keys — or even when you put on your shoes. If your dog is now reacting to pre-departure cues (coat, bag, keys) before you’ve even left, the anxiety has escalated significantly.

2. Destructive Behaviour Is Increasing in Severity

Mild separation anxiety might mean a chewed shoe. Worsening anxiety means destroyed furniture, ripped carpets, scratched doors, and shredded bedding. If the damage is getting worse with each absence — or spreading to new areas of the home — the anxiety is intensifying. Destructive behaviour is your dog’s attempt to cope with overwhelming distress, not deliberate misbehaviour.

3. Your Dog Is Injuring Themselves

This is a serious escalation sign. Dogs with severe separation anxiety sometimes injure themselves trying to escape — broken nails, bleeding paws from scratching at doors, or injuries from attempting to break through barriers. If you’re coming home to any signs of self-injury, seek veterinary help immediately.

4. Indoor Accidents Are Happening More Frequently

A house-trained dog having accidents only when left alone is a classic separation anxiety sign. If those accidents are becoming more frequent, happening sooner after you leave, or occurring even during short absences, the anxiety is worsening. This is not a house-training problem — it’s an anxiety response.

5. Your Dog Won’t Eat or Drink While You’re Away

Anxiety suppresses appetite. If your dog is refusing food or water during your absences — even when meals are left out — the anxiety is severe enough to override basic biological drives. This is a significant warning sign that requires professional attention.

6. The Anxiety Is Triggered by Shorter and Shorter Absences

Early separation anxiety might only appear during long absences. As it worsens, the threshold drops — your dog becomes distressed when you leave for 30 minutes, then 10 minutes, then just stepping outside to check the post. If your dog can no longer tolerate even brief separations, the condition has progressed significantly.

7. Pre-Departure Anxiety Is Developing

Dogs with worsening separation anxiety begin to anticipate your departure and show distress before you’ve even left. Signs include pacing, panting, trembling, or shadowing you as you prepare to go out. If your dog is now anxious during your morning routine — not just after you leave — the anxiety has become anticipatory, which is a more advanced stage.

8. Your Dog Is Becoming Clingy Between Absences

Worsening separation anxiety often bleeds into your time at home. Your dog follows you everywhere, becomes distressed when you close a door between you, or cannot settle unless physically touching you. This hyper-attachment is both a symptom and a driver of worsening anxiety — the more dependent the dog becomes, the harder separation feels.

9. Neighbours Are Reporting Constant Noise

If neighbours are mentioning that your dog barks, howls, or whines continuously while you’re out — not just for a few minutes — the anxiety is severe. Sustained vocalisation throughout your absence indicates your dog is not settling at all, which is both a welfare concern and a sign that the condition needs urgent attention.

10. Your Dog’s Physical Health Is Being Affected

Chronic anxiety takes a physical toll. Watch for weight loss from not eating during absences, digestive issues, a dull coat, or increased susceptibility to illness. If your dog’s vet visits are increasing alongside the behavioural signs, the anxiety may be affecting their immune system and overall health.

11. Nothing You’ve Tried Is Working Anymore

If strategies that previously helped — a Kong toy, background TV, a worn item of your clothing — are no longer making any difference, the anxiety has progressed beyond what simple management tools can address. This is a clear signal that professional intervention is needed.

Why Does Separation Anxiety Get Worse Over Time?

Separation anxiety is self-reinforcing. Each distressing separation confirms to your dog that being alone is dangerous and unbearable. Without intervention, the anxiety deepens with every absence. The dog’s threshold for distress lowers, their coping capacity shrinks, and the condition becomes harder to treat.

This is why early intervention matters so much. A dog showing 2–3 of the signs above is far easier to help than a dog showing 8–9.

What to Do If Your Dog’s Separation Anxiety Is Getting Worse

Step 1 — See Your Vet First

Before starting any behavioural programme, rule out medical causes. Pain, thyroid issues, and neurological conditions can all worsen anxiety. Your vet can also discuss medication options — anti-anxiety medication is not a last resort, it’s a legitimate tool that makes behavioural training significantly more effective in moderate to severe cases.

Step 2 — Stop Reinforcing the Anxiety

Avoid dramatic departures and arrivals. Long, emotional goodbyes increase your dog’s anticipatory anxiety. Calm, matter-of-fact departures — and low-key returns — help your dog learn that your leaving and returning is unremarkable.

Step 3 — Start Systematic Desensitisation

This is the gold standard treatment for separation anxiety. The process involves exposing your dog to very short separations — seconds, not minutes — and gradually increasing the duration as your dog remains calm. The key is never exceeding your dog’s threshold. Progress is slow but lasting.

For dogs with moderate to severe anxiety, working with a certified separation anxiety trainer (CSAT) produces the best outcomes.

Step 4 — Use Calming Aids as Support Tools

Calming supplements, pheromone diffusers, and anxiety wraps can reduce baseline anxiety and make behavioural training more effective. They work best as support tools alongside a structured programme — not as standalone fixes.

Step 5 — Increase Exercise and Mental Stimulation

A physically and mentally tired dog has lower baseline anxiety. A long walk before a planned absence, a puzzle feeder at departure, and regular enrichment throughout the day all reduce the intensity of separation anxiety over time.

Frequently Asked Questions

Can separation anxiety in dogs get worse with age?

Yes. Without intervention, separation anxiety typically worsens over time as each distressing separation reinforces the dog’s belief that being alone is dangerous. Senior dogs may also develop worsening anxiety due to cognitive dysfunction or increased pain. Early treatment produces the best outcomes.

How do I know if my dog has severe separation anxiety?

Severe separation anxiety involves self-injury, continuous vocalisation throughout absences, complete refusal to eat or drink when alone, and distress that begins before you’ve even left. If your dog is showing these signs, veterinary involvement — including possible medication — is strongly recommended.

Can separation anxiety be cured?

Many dogs with separation anxiety make significant and lasting improvement with systematic desensitisation, environmental management, and — where needed — medication. Some dogs require ongoing management rather than a complete cure, but quality of life can be dramatically improved at any stage.

Should I get another dog to help with separation anxiety?

Not as a first response. A second dog may provide some comfort, but dogs with true separation anxiety are attached to their owner — not to other dogs. A second dog will not resolve the anxiety and may add complexity to the household. Address the anxiety first through proper treatment.

How long does it take to treat separation anxiety in dogs?

Mild cases can show significant improvement within 4–8 weeks of consistent desensitisation. Moderate to severe cases typically take 3–6 months or longer. Progress depends on the dog’s baseline anxiety, consistency of training, and whether medication is used to support the process.

Final Thoughts

Separation anxiety doesn’t fix itself — but it absolutely can be fixed with the right approach. If you’ve recognised several of the warning signs above, the most important thing you can do right now is act. Speak to your vet, start reducing your dog’s baseline anxiety today, and consider working with a professional if the anxiety is moderate or severe.

Your dog isn’t trying to punish you for leaving. They’re struggling — and they need your help. 🐾
