What Can I Give My Dog for Anxiety?

✓ Vet-referenced✓ Sources citedUpdated 2026-10-10

Usually mild

For mild anxiety, start with exercise, a predictable routine, a safe den-like space, calming pheromone diffusers and pressure wraps. For fireworks, storms or travel, your vet can prescribe medicines made for this purpose. Benadryl is unreliable for anxiety, and many calming supplements are not regulated, so ask your vet first.

See a vet now if you notice:
  • Your dog injures itself trying to escape
  • Sudden behavior change in an older dog (could be pain or illness)
  • Aggression linked to fear
  • Refusing food for more than a day

Safe ways to calm an anxious dog

  1. Exercise and mental enrichment (puzzle feeders, sniff walks) before stressful events.
  2. Create a safe space: a covered crate or quiet room with bedding, and white noise or calm music to mask sounds.
  3. Try a dog-appeasing pheromone (DAP) diffuser or collar.
  4. Pressure wraps (anxiety vests) help some dogs during storms.
  5. Stay calm yourself; comforting your dog is fine and does not "reward" fear.
  6. For long-term fears, gradual desensitization and counter-conditioning, ideally with a trainer or veterinary behaviorist.

Medicines vets use for dog anxiety

  • Situational anxiety (fireworks, storms, vet visits, travel): dexmedetomidine oral gel, trazodone or gabapentin, given before the event
  • Ongoing anxiety (separation anxiety, generalized fear): daily medicines such as fluoxetine or clomipramine, combined with behavior training
  • Melatonin is sometimes suggested by vets for noise fears; choose a product without xylitol and ask for the dose

What to avoid

  • Punishing fearful behavior, which makes anxiety worse
  • Giving another pet's or a person's sedatives
  • CBD or "calming" products with unknown contents: some contain THC or xylitol
  • Relying on Benadryl: it sedates some dogs, excites others, and does not treat fear

Signs of anxiety in dogs

  • Panting, pacing, trembling or hiding
  • Drooling, yawning, lip licking
  • Destructive chewing or scratching at doors (often separation anxiety)
  • Barking, howling or accidents in the house
  • Escape attempts

Frequently asked questions

Can I give my dog Benadryl for anxiety?

It is not a good anxiety treatment. Its sedating effect is unpredictable and it does not reduce fear. Ask your vet about medicines made for situational anxiety.

Can I give my dog melatonin?

Some vets recommend melatonin for noise fears or sleep. Ask for the dose and use a product without xylitol or other additives.

How can I calm my dog during fireworks?

Walk your dog before dark, close curtains, play music or white noise, provide a hiding spot and ask your vet about medication ahead of time.
