Dog Anxiety: Signs, Causes and Treatment Options in the UK

Anxiety is one of the most common behavioural issues in UK dogs and is significantly underdiagnosed. Whether triggered by fireworks, separation, loud noises, or past trauma, anxiety causes real distress and can have serious impacts on both a dog's welfare and the owner's daily life. The good news is that effective treatments are available.

Recognising the Signs of Anxiety in Dogs

Anxiety in dogs manifests in a wide variety of ways, and not all owners recognise these behaviours as anxiety-related. Classic signs include: trembling or shaking; panting excessively in the absence of heat or exercise; pacing, restlessness, and inability to settle; yawning, lip-licking, or 'whale eye' (showing the whites of the eyes) in stressful situations; attempting to escape or hide; vocalisation including whining, barking, or howling; and destructive behaviour when left alone.

More subtle signs include a tucked tail, flattened ears, crouching, avoiding eye contact, and losing bowel or bladder control. Some dogs with chronic anxiety may display compulsive behaviours such as tail-chasing, light-chasing, or repetitive pacing.

The PDSA's PAW Report highlights anxiety and behavioural problems as significantly underaddressed in the UK dog population. Many owners attribute anxiety behaviours to 'naughtiness' or stubbornness rather than distress — understanding that these behaviours are symptoms of a welfare problem is the first step to helping.

Common Types of Dog Anxiety

Separation anxiety is one of the most prevalent forms, affecting an estimated 14–17% of dogs. It occurs when dogs become distressed at being left alone — manifesting as destructive behaviour, excessive vocalisation, toileting in the house, and sometimes self-harm. The COVID-19 pandemic and subsequent return to office work significantly worsened separation anxiety across the UK dog population.

Noise phobia — particularly to fireworks, thunderstorms, and traffic — is also extremely common. Fireworks are a particularly significant issue in the UK, with dogs displaying signs of distress around Bonfire Night, New Year, and Diwali celebrations. Signs range from mild trembling to full panic.

Other forms include social anxiety (fear of other dogs or strangers), generalised anxiety disorder (persistent, non-specific anxiety), and situational anxiety triggered by specific contexts such as vet visits or car journeys. Many dogs experience multiple forms concurrently.

Treatment Options: From Behaviour to Medication

Effective management of dog anxiety typically involves a combination of approaches. Behaviour modification — working with a qualified clinical animal behaviourist or accredited behaviourist — is the cornerstone of treatment. Techniques include desensitisation (gradual, controlled exposure to the fear trigger), counter-conditioning (associating the trigger with positive experiences), and structured training programmes.

For noise phobia, the RCVS and BVA recommend early preparation for fireworks season, including the use of desensitisation sound tracks (such as the Dogs Trust's Sound Therapy for Pets), appropriate dens or safe spaces, and, where needed, medication.

Prescription anxiolytic medications are available for dogs with moderate to severe anxiety. These include: dexmedetomidine oromucosal gel (Sileo) for acute noise phobia; alprazolam or diazepam for situational anxiety; and fluoxetine or clomipramine for long-term management of separation anxiety and generalised anxiety. These are all prescription-only medicines — your vet can advise on the most appropriate option. If long-term medication is prescribed, a written prescription to use at an online pharmacy can reduce monthly costs significantly.

Practical Measures for an Anxious Dog

Alongside professional behaviour support and veterinary treatment, there are practical measures owners can take to help an anxious dog. For separation anxiety, practices recommended by the PDSA and Dogs Trust include: never making a fuss of arrivals and departures; practising very short absences and building gradually; providing enrichment such as Kong toys; and considering dog daycare or a dog sitter if long absences are unavoidable.

For noise phobia, during fireworks: keep the dog indoors with all windows and curtains closed; provide a den or hiding place (never force them out); put on a radio or television to mask the noise; use a ADAPTIL diffuser or collar (dog-appeasing pheromone); and remain calm yourself, as dogs are sensitive to owner anxiety. These measures are most effective when combined with advance preparation and, if needed, medication from your vet.

Over-the-counter calming products — including Zylkène (casein-based), Yucalm, and various herbal products — have variable evidence of efficacy. Some dogs respond well; others do not. They may be worth trying for mild anxiety but are unlikely to be sufficient for moderate to severe cases.

Getting Help for an Anxious Dog

If your dog's anxiety is significantly affecting their quality of life or your own, speak to your vet as the first step. They can rule out medical causes for behavioural changes and refer you to a qualified clinical animal behaviourist. In the UK, look for behaviourists accredited by the Animal Behaviour and Training Council (ABTC) or members of the Association of Pet Behaviour Counsellors (APBC).

Long-term anxiolytic medication, if needed, can be expensive. A monthly supply of fluoxetine for a medium dog might cost £20–£40 at a vet practice. Using a written prescription at an online pharmacy under the March 2026 CMA reforms can reduce this cost by 40–60%.
