What Can I Give My Dog for Anxiety? Safe Options, From Routine to Supplements

The short answer

If you're asking "what can I give my dog for anxiety?", the most effective things usually aren't things you give at all. A predictable routine, enough exercise, a safe place to retreat to and gradual training do the heavy lifting. On top of that, a calming supplement with research-backed ingredients such as L-theanine can help some dogs feel more settled, and for moderate to severe anxiety, your veterinarian can prescribe medication. What you should not do is reach into your own medicine cabinet.

I learned this the hard way with my corgi, Waffles, who is perfect in every way except for thunder. Below is everything I wish I'd known before that first summer of storms: how to tell whether your dog is anxious, what helps most, how to judge a calming supplement, and when it's time to call the vet.

First, is it really anxiety?

Before deciding what to give your dog, it helps to know what you're dealing with. Anxiety is a dog anticipating a threat, and it shows up in the body and in behavior. Common signs include:

• Pacing, restlessness or being unable to settle
• Panting, drooling or trembling when it isn't hot
• Whining, barking or howling
• Yawning, lip licking or a tucked tail
• Hiding, clinginess or following you room to room
• Chewing, digging or scratching at doors and windows
• Accidents in the house or a sudden loss of appetite

The Merck Veterinary Manual lists many of these as signs of fear and anxiety, and estimates that around 14% of dogs have separation anxiety alone.

Find the trigger

Most anxious dogs are reacting to something specific. Write down when the signs appear for a week or two. Typical triggers are:

• Loud noises: thunderstorms, fireworks, construction
• Being left alone
• Car rides and vet visits
• Grooming and nail trims
• Visitors, holidays, a new baby, a move

Knowing the trigger tells you whether you need everyday support, help for a predictable event, or both. It also gives your vet useful information if you need them.

One caution: pain and illness can look like anxiety. A dog who suddenly becomes restless, clingy or snappy should see a vet first, especially an older dog.

What helps most: calming your dog naturally at home

These steps cost little or nothing, have no side effects, and make everything else work better. Start here even if you plan to use a supplement.

1. Keep the day predictable

Dogs relax when they know what comes next. Feed, walk and go to bed at roughly the same times. Before a known stressor, such as a storm in the forecast or a long day out, keep the rest of the routine as normal as possible.

2. Burn off energy first

A tired dog copes better. The ASPCA recommends plenty of physical and mental exercise as a foundation for anxious dogs. A long sniff walk before a stressful event is one of the simplest things you can do.

3. Give them a safe space

Set up a quiet, den-like spot: a covered crate (left open), a closet with a bed, or an interior room away from windows. The American Kennel Club suggests a dark, covered space plus background noise like white noise or soft music during storms. Let your dog go there on their own, and never punish fearful behavior.

4. Give the anxiety somewhere to go

Chewing and licking are self-soothing for dogs. A lick mat spread with plain yogurt or pumpkin, a stuffed food toy or a long-lasting chew gives an anxious dog something calming to do with their mouth.

5. Train calm, a little at a time

For anxiety that keeps coming back, behavior training makes the biggest long-term difference. The two core techniques are:

• Desensitization: exposing your dog to a very mild version of the trigger (thunder sounds at low volume, or you picking up your keys without leaving) and slowly building up.
• Counterconditioning: pairing the trigger with something great, such as a favorite treat, so it starts to predict good things.

Go slowly. If your dog starts showing stress signs, you've gone too far. A certified trainer or veterinary behaviorist can help with stubborn cases.

6. Stay calm yourself

Dogs read our mood. Comforting a scared dog won't "reward" fear, so it's fine to sit with them and stroke them slowly. What doesn't help is panicking, scolding or forcing them out of hiding.

Calming supplements: what can you give a dog for anxiety without a prescription?

Calming supplements are the most common answer to "what can I give my dog to calm him down?" They won't fix a deep-rooted phobia on their own, but alongside the steps above they can help some dogs feel more settled. The key is knowing which ingredients have research behind them and how to read a label.

Ingredients worth knowing

• L-theanine. An amino acid from tea leaves and the best-studied calming ingredient for dogs. In a 2010 study published in the Journal of Veterinary Behavior, dogs given L-theanine approached and interacted with an unfamiliar person more than dogs on a placebo. A 2015 open-label study of storm-sensitive dogs found fewer signs such as pacing, panting and hiding, with high owner satisfaction. Both studies were small, so the evidence is promising rather than conclusive. Read more in our L-theanine guide.
• GABA. A naturally occurring compound involved in the body's calming signals, often paired with L-theanine. GABA guide
• Chamomile. A gentle botanical with a long history of traditional use. Research in dogs is limited. Chamomile guide
• Omega-3 fatty acids and probiotics. Not calming ingredients in themselves, but they support overall wellness and are often included in daily formulas.

How to read a calming supplement label

1. Check the full ingredient list. You should be able to see every ingredient, not just a "proprietary blend" name.
2. Look for weight-based servings. A 10 lb dog and a 70 lb dog shouldn't get the same amount.
3. Make sure it's made for dogs. Human supplements can contain ingredients that are dangerous to dogs, including the sweetener xylitol.
4. Ask what "calm" means. Some products are designed to make dogs drowsy. Others aim to take the edge off while your dog stays alert and playful. Choose the one that fits your goal.
5. Look for quality signals. Independent batch testing, a manufacturing facility audited by the National Animal Supplement Council (NASC), and a company that answers questions clearly.
6. Be wary of big promises. Supplements support calm. They don't "cure" anxiety, and no honest brand will say they do.

Chews or drops?

Soft chews are easy for most dogs, since they take them like a treat. Liquid drops suit picky eaters and dogs who refuse chews, because you can give them directly or mix them into food or water. We compare the two in Calming Drops vs. Calming Chews.

How Kindoly® fits in. We made Kindoly® because I wanted Waffles to be less afraid of thunder and still be Waffles. Both of our formulas combine L-theanine, chamomile and GABA, are sedative-free, and come with weight-based serving directions. Everyday Calm Drops start working in as little as 30 minutes, and Everyday Calm Soft Chews in as little as 40 minutes. For ongoing support, give a serving daily: most dogs settle into a steadier baseline within 3 to 5 days. Every batch is independently tested by SGS.

What about over-the-counter medicine for dog anxiety?

"What can you give a dog for anxiety over the counter?" is one of the most searched questions on this topic, and the safest answer is: nothing from your own medicine cabinet unless your vet tells you to.

• Many human medications are toxic to dogs. Pain relievers are among the most toxic, according to the University of Illinois College of Veterinary Medicine. The MSD Veterinary Manual describes how common over-the-counter drugs can poison dogs.
• Antihistamines such as Benadryl are sometimes suggested by vets for specific situations, but they are not an anxiety treatment. The right dose depends on your dog, and some formulas contain other ingredients that aren't safe. Only use one on your vet's advice.
• Melatonin is mainly used for sleep, not anxiety. VCA Animal Hospitals warns that human melatonin products may contain xylitol, which is toxic to dogs.
• Never share your own anti-anxiety or sleep medication. Drugs that are safe for people can be dangerous for dogs, even in small amounts.

If your dog swallows a human medication, call your vet or the ASPCA Animal Poison Control Center at (888) 426-4435 right away.

For dogs who need real sedation, for surgery, a difficult procedure or a long flight, that is a decision for your veterinarian.

When to see your vet

Routine changes and supplements are a good fit for everyday stress and predictable events. Talk to your veterinarian if:

• Your dog could hurt themselves, for example by breaking out of a crate, chewing through doors or jumping through windows
• The anxiety is getting worse, or happens most days
• Your dog stops eating, or has accidents in the house that are new
• The change in behavior is sudden, or your dog is a senior (pain and age-related changes can look like anxiety)
• You've tried the steps above consistently for several weeks without improvement

Your vet can rule out medical causes, prescribe anti-anxiety medication when it's needed, and refer you to a veterinary behaviorist. Medication and supplements can be used alongside training, so ask your vet before combining anything with a prescription.
