Anxiety is one of the most common behavioral issues in dogs — and one of the most frequently misread. Chewed furniture gets labeled as bad behavior. Accidents in the house get called stubbornness. Barking gets dismissed as attention-seeking. Often, these are anxiety, and treating them as discipline problems makes things worse.
Here's how to recognize anxiety in dogs and what you can actually do about it.
Physical Signs of Anxiety
Panting. Panting when it's not hot and your dog hasn't been exercising is a classic anxiety signal. Stress panting tends to be faster and shallower than heat panting.
Yawning. In dog body language, yawning frequently (especially when not tired) is a calming signal — an attempt to self-regulate stress.
Excessive licking. Lip licking, air licking, or obsessively licking their paws or other body parts can all be stress responses. Paw licking that leads to red, raw "hot spots" is often anxiety-driven.
Shaking or trembling. Not just from cold — trembling during thunderstorms, vet visits, car rides, or other triggers is a fear response.
Dilated pupils. Fear and anxiety activate the sympathetic nervous system, causing pupil dilation. In a stressed dog, eyes may appear wider or more intense than usual.
Whale eye. When a dog shows the whites of their eyes (the sclera) by turning their head but keeping eyes forward, it often indicates discomfort or anxiety.
Shedding. Dogs can shed significantly more during stressful events. You might notice a cloud of fur at the vet that wasn't there on the drive over.
Tucked tail. A tail held low or tucked between the legs is a well-known fear signal.
Ears back. Flattened or pulled-back ears typically indicate submission or anxiety.
Behavioral Signs of Anxiety
Destructive behavior. Chewing furniture, shoes, baseboards, or household items — especially when left alone — is a hallmark of separation anxiety. A dog that's otherwise well-behaved but destroys things in your absence is anxious, not spiteful.
Excessive barking or whining. Persistent vocalization, particularly when left alone or in response to specific triggers like thunderstorms or strangers.
Pacing. Unable to settle, walking back and forth, circling — a dog that can't find a comfortable spot to rest may be too anxious to relax.
Hiding. Seeking out small, enclosed spaces — under beds, in closets, behind furniture — is a self-soothing behavior in anxious dogs.
Clinginess. Staying unusually close to their owner, following them from room to room, becoming distressed when even briefly separated.
House training regression. A dog that suddenly has accidents indoors after being reliably trained may be experiencing anxiety rather than a training failure.
Escape attempts. Digging under fences, scratching at doors, or breaking out of crates can be driven by separation anxiety or fear of specific triggers.
Aggression. Fear-based aggression is a common anxiety manifestation — a dog that snaps, growls, or bites when approached in certain situations may be acting from anxiety rather than dominance.
Common Triggers
Separation anxiety — being left alone. One of the most common forms of anxiety in dogs.
Noise phobia — thunderstorms, fireworks, construction, gunshots. Some dogs develop severe phobic responses to specific sounds.
Social anxiety — fear of strangers, unfamiliar dogs, new environments, or crowds.
Situational anxiety — car rides, vet visits, grooming appointments.
Change — new home, new family member, change in routine.
What Actually Helps
Identify the trigger. Anxiety management starts with knowing what causes it. Keeping a log of when episodes happen helps identify patterns.
Behavior modification. Gradual desensitization (slowly increasing exposure to the trigger at a level below the anxiety threshold) and counter-conditioning (pairing the trigger with something positive) are the most evidence-backed approaches. Working with a certified animal behaviorist or veterinary behaviorist gives the best results.
Exercise. Physical activity reduces baseline anxiety in dogs. A tired dog has less energy available for anxious behavior.
Predictable routine. Dogs find predictability calming. Consistent meal times, walk times, and sleep arrangements reduce baseline stress.
Safe space. A crate or specific area the dog associates with safety and calm — not punishment — gives anxious dogs somewhere to decompress.
Medication. For moderate to severe anxiety, behavioral medication prescribed by a vet can make a significant difference. It doesn't replace training, but it brings anxiety down to a level where the dog can actually learn. Don't dismiss this option as a last resort — it's often the tool that makes everything else work.
Calming aids. Thundershirts, pheromone diffusers (Adaptil), and calming supplements have variable evidence but work well for some dogs, particularly for situational anxiety. Worth trying as a complement to other approaches.
The Short Version
Anxiety in dogs shows up physically and behaviorally — and most "bad behavior" in otherwise well-trained dogs is worth evaluating as anxiety before approaching it as a discipline issue. If your dog's anxiety is affecting their quality of life or yours, a vet or certified behaviorist is the right next step. Effective help exists, and anxiety is manageable in the vast majority of dogs.
