"What can I give my dog for anxiety?"

If you've typed that into a search bar at 9 p.m. while fireworks are going off, you're not alone. It's one of the most common questions dog parents ask, and the answers online range from genuinely helpful to downright risky.

This guide puts every common option side by side: what it is, what it's best for, whether it makes dogs drowsy, and what the evidence actually says. We make sedative-free calming chews and drops, so we're not a neutral party. That's exactly why this guide covers the options we don't sell, too, and tells you when a supplement isn't the right answer.

What Can I Give My Dog for Anxiety? All the Options Compared

Calm and Alert, or Calm and Sleepy?

One of the biggest differences between options is whether they sedate. That matters: a drowsy dog isn't the same as a relaxed one, and most owners want their dog to still feel like themselves on a car ride or at the vet.

Natural and Over-the-Counter Options

L-theanine

L-theanine is an amino acid found naturally in green tea, associated with relaxation without sedation. A few small studies have looked at it in dogs, including an open-label study of storm-sensitive dogs in the Journal of Veterinary Behavior (Pike et al., 2015), where owners reported improvements in many anxious behaviors. To be honest about the evidence: these studies were small and not placebo-controlled, so the research is encouraging rather than conclusive. More in our guide to L-theanine for dogs.

Chamomile

One of the gentlest calming botanicals, and common in calming chews. Dog-specific research is limited, so think of it as part of a broader approach rather than a stand-alone fix. Skip it if your dog is allergic to daisy-family plants. See chamomile for dogs.

Valerian root

A traditional calming herb. At typical supplement levels it supports relaxation, but a small number of dogs react the opposite way and become more restless, which is why it's smart to try any new product on a quiet day first. Read valerian root for dogs.

GABA and tryptophan

Both are involved in how the body regulates mood, and they often appear together in calming formulas meant for daily use. See GABA for dogs.

Melatonin

Melatonin is used "off label" in dogs for sleep and some behavior issues, and it often makes dogs drowsy, which can help at bedtime but isn't ideal for daytime stress. VCA Animal Hospitals advises that melatonin use be guided by your vet and warns that some human melatonin products contain xylitol, which is toxic to dogs. Read our full guide on melatonin for dogs.

CBD

CBD is everywhere in pet aisles, but the FDA considers CBD products for animals unapproved and has issued warning letters to companies making unproven claims that their products treat stress or anxiety in pets. Products also vary widely in how much CBD they actually contain. If you're considering CBD, talk to your vet first, especially if your dog takes other medications.

Pheromones and pressure wraps

Dog-appeasing pheromone diffusers and collars, and snug pressure wraps, are drug-free and low-risk. Results are mixed: some dogs clearly benefit, others don't respond. They can be a good extra layer during storm and fireworks season. Compare them in calming vests vs. natural calming supplements.

Prescription Options From Your Vet

If your dog's fear is intense (panting, drooling, trembling, trying to escape, injuring themselves), a supplement alone may not be enough, and that's okay. Your veterinarian can prescribe medications made for dogs, including FDA-approved treatments for noise aversion and separation anxiety. In May 2026, the FDA approved Tessie (tasipimidine), the first drug approved to treat both conditions. Many dogs do best with medication plus behavior training.

What to Give Your Dog for Specific Situations

Thunderstorms and fireworks

Combine a quiet safe space, white noise and a calming supplement given ahead of time. Dogs with severe noise fear often benefit from a vet consultation before the season starts. See thunderstorm tips and fireworks season.

Car rides and travel

Separate nerves from motion sickness: drooling and vomiting may mean nausea, which needs a different approach. Start with short, positive trips. See car travel with dogs.

Vet visits and grooming

Practice handling at home, bring high-value treats, and ask your clinic about fear-free appointments. A calming supplement given 30–60 minutes beforehand can help with mild nerves. Read helping your dog feel calmer at the vet.

Being home alone

True separation anxiety usually needs gradual training, and sometimes medication. Supplements can support the process but won't replace it. Our full guide: separation anxiety in dogs.

Halloween and holiday guests

Doorbells, costumes and an open front door add up. Set up a quiet room and plan ahead. See Halloween dog safety.

Calming Strategies That Don't Come in a Bottle

• Create a safe space: a quiet room or covered crate with their bed, water and a familiar blanket.
• Keep routines predictable: regular walks, meals and bedtime help dogs feel secure. See how to create a calm daily routine.
• Exercise and enrichment: a tired, mentally engaged dog copes better with stress.
• Desensitization: play triggers like doorbell or thunder sounds at a very low volume, pair them with treats, and slowly increase.
• Learn your dog's signals: yawning, lip licking, whale eye and pacing are early signs of stress. See understanding dog body language.
• Don't overlook the gut: stress and digestion are closely linked. See the gut-brain connection in dogs.

The Bigger Picture

There's no single "best" thing to give an anxious dog. For everyday and situational stress, a non-sedating supplement plus a safe space and a steady routine helps many dogs feel more like themselves. For severe or sudden anxiety, your veterinarian is the best first call. Whatever you choose, start on a calm day, watch closely, and adjust.
