Dog Anxiety or Restlessness - Causes, Diagnosis & When to See a Vet
> Disclaimer: This article is for educational purposes only and is not a substitute for professional veterinary advice, diagnosis, or treatment. Always consult your veterinarian when your dog shows behavioral or medical concerns.
Quick Summary
Anxiety and restlessness in dogs can stem from behavioral triggers, medical conditions, or a combination of both. Common signs include pacing, trembling, panting, and avoidance. While separation anxiety and noise phobias are familiar causes, pain, thyroid imbalances, and neurological issues can also produce anxious behavior. A veterinary exam helps distinguish medical from behavioral causes and guides appropriate treatment.
What Does Anxiety or Restlessness Look Like in Dogs?
Dogs may show anxiety or restlessness through:
- Pacing or circling – Inability to settle in one place
- Trembling or shaking – Especially during storms or when left alone
- Excessive panting – Without heat or exercise
- Whining, barking, or howling – Often when owners leave or during storms
- Hiding or clinging – Seeking comfort or escape
- Destructive behavior – Chewing, digging, or scratching when anxious
- Restlessness at night – Difficulty settling for sleep
Common Causes of Anxiety or Restlessness in Dogs
- Separation anxiety – Stress when left alone; often seen in breeds that bond strongly (Labrador Retrievers, German Shepherds, Cavalier King Charles Spaniels).
- Noise phobia – Fear of thunder, fireworks, or loud machinery. Common in herding and hunting breeds (Border Collies, Cocker Spaniels).
- Pain or discomfort – Arthritis, dental disease, or internal illness. Dogs may pace or appear restless when lying down is painful.
- Cognitive dysfunction syndrome – Older dogs may pace at night, appear confused, or show sundowning. Common in dogs over 10.
- Hyperthyroidism (rare in dogs) – More common is hypothyroidism affecting energy; thyroid testing helps rule out metabolic causes.
- Cushing's disease – Excess cortisol can cause increased thirst, panting, and restlessness. Common in older, small to medium breeds.
- Neurological conditions – Seizures, vestibular disease, or brain changes can cause anxiety-like behavior.
- Gastrointestinal upset – Nausea or abdominal pain may cause pacing and unease.
- Environmental changes – Moving, new pets, schedule changes, or loss of a family member.
- Breed predisposition – Breeds like Greyhounds, Vizslas, and Australian Shepherds may be more prone to anxiety-related behaviors.
When Is Anxiety or Restlessness an Emergency?
Seek immediate veterinary care if your dog:
- Cannot settle and shows signs of severe distress (extreme panting, collapse)
- Has ingested a toxin or medication
- Shows neurological signs (staggering, seizures, disorientation)
- Exhibits restlessness with vomiting, bloating, or obvious pain
- Has attempted to escape and injured themselves
How Veterinarians Diagnose the Cause
The diagnostic approach includes:
- History – Onset, triggers, duration, and any life changes
- Physical exam – Assessment for pain, abdominal discomfort, or neurological abnormalities
- Bloodwork – Thyroid, cortisol, CBC, and chemistry to screen for metabolic and organ issues
- Imaging – X-rays or ultrasound if abdominal or musculoskeletal concerns
- Behavioral questionnaire – To assess separation anxiety, noise phobia, or generalized anxiety
- Rule-out for pain – Trial of pain medication in seniors when arthritis is suspected
Treatment Options
- Behavioral modification – Desensitization, counter-conditioning, and gradual exposure with positive reinforcement
- Environmental enrichment – Puzzle toys, safe spaces, predictable routines, and calming aids (e.g., pheromone diffusers)
- Medication – Anti-anxiety drugs (SSRIs, trazodone) or situational medications (e.g., for storms) prescribed by a vet
- Medical treatment – Pain management, thyroid supplementation, or treatment for Cushing's when indicated
- Training – Separation anxiety protocols, crate training when appropriate
Prevention Tips
- Socialize puppies early with positive experiences
- Create predictable routines and safe resting areas
- Provide adequate exercise and mental stimulation
- Avoid punishment; use reward-based training
- Consider calming supplements or pheromones for known triggers (consult your vet first)
