The best calming chew for most dogs is VetriScience Calm & Confident, formerly sold as Composure. It is a practical first option for predictable stress because its formula is clearly identified, it can be given daily or as needed, and VetriScience says it typically works within 30 minutes and lasts up to four hours. VetriScience renamed the Composure range in 2024.
For more serious anxiety, VetriScience Veterinary Strength Calm & Confident, formerly Composure Pro, provides a stronger over-the-counter option. Severe separation anxiety, panic, aggression or destructive escape behavior usually requires a veterinary behavior plan rather than calming chews alone.

Why VetriScience Calm & Confident Is the Best Overall Choice
VetriScience Calm & Confident is the best starting point when your dog becomes nervous during predictable events such as thunderstorms, fireworks, car rides, boarding, grooming or visitors.
The formula contains L-theanine, thiamine and a colostrum-derived calming complex. The product is not marketed as a sedative, and VetriScience says it can be used daily or as needed. The standard dosage is one chew for dogs up to 50 pounds, two chews for dogs weighing 51 to 100 pounds, and three chews for dogs over 100 pounds.
VetriScience reports that 21 of 30 dogs in its field trial were rated "very effective" by their owners. This is manufacturer-reported evidence, not an independent clinical trial, so it supports the product without proving that it will work for every dog.
The product also offers:
- Clear weight-based dosing
- Daily or as-needed use
- Several named active ingredients
- A reported onset of approximately 30 minutes
- Chicken, bacon and peanut butter flavors
- A current product name that may still appear as "Composure" in retailer searches
Calm & Confident is the current name for the standard Composure formula. Veterinary Strength Calm & Confident replaced Composure Pro.
Best Stronger Option: Veterinary Strength Calm & Confident
Veterinary Strength Calm & Confident is the better choice when standard calming chews have not provided enough support for occasional high-stress events.
The formula contains Colostrum Calming Complex, L-theanine, thiamine and L-tryptophan. VetriScience says it is clinically shown to work within 30 minutes and last up to four hours. The label allows daily or as-needed use, with an increased amount permitted during heightened stress.
The standard directions are:
- Up to 30 pounds: ½ chew
- 31 to 60 pounds: 1 chew
- 61 pounds or more: 2 chews
Veterinary Strength Calm & Confident is still a supplement, not a prescription anxiety treatment. A dog that panics, injures itself, tries to escape, cannot remain alone or shows aggression needs a veterinary examination and behavior assessment.
Best for Daily Mild Stress: Solliquin Soft Chews
Solliquin is a good alternative for dogs that need ongoing support for mild or moderate stress rather than a quick, one-time solution.
Solliquin combines L-theanine, magnolia and phellodendron extracts, along with a whey protein concentrate called NMXSLQ05. The manufacturer describes the formula as non-sedating and intended for daily use alongside behavior modification.
For the small and medium dog formula, each soft chew contains:
- Magnolia and phellodendron extracts: 75 mg
- L-theanine: 35 mg
- Whey protein concentrate: 25 mg
The listed daily dose is ½ chew for dogs under 8 pounds, one chew for dogs weighing 8 to 15 pounds, and two chews for dogs weighing 16 to 30 pounds. Medium and large dogs use a higher-strength formula.
Solliquin may suit dogs that become unsettled by routine changes, visitors, travel or a generally stimulating home environment. It should not be treated as a complete solution for severe separation anxiety.
Best Simple Formula: Virbac Anxitane
Virbac Anxitane is the best option if you want a chewable tablet based on one active ingredient, L-theanine.
Anxitane contains synthetic L-theanine in two strengths: 50 mg for smaller dogs and 100 mg for medium and large dogs. Virbac describes it as a supplement for mild to moderate environmentally induced stress and says it is intended to promote relaxation without drowsiness.
Anxitane may suit owners who prefer a shorter ingredient list instead of a blend containing several herbs and supplements. Virbac states that Anxitane is not intended for dogs with severe phobias, separation anxiety or a known history of aggression.
Best for Nighttime Restlessness: NaturVet Quiet Moments
NaturVet Quiet Moments is more suitable when rest and nighttime relaxation are part of the problem.
The soft chews contain melatonin, chamomile, L-tryptophan, thiamine and ginger. NaturVet states that the product is for dogs over 12 weeks old and positions it for car rides, thunderstorms, fireworks, vet visits and bedtime routines.
Because it contains melatonin, Quiet Moments is not my first choice for a dog that needs to remain alert during training, travel or daytime social situations. Ask your veterinarian before using melatonin if your dog takes medication or has an underlying health condition.
Do Calming Chews Actually Work?
Calming chews can help some dogs with mild or situational stress, but they do not work reliably for every dog. Veterinary references describe the evidence for natural calming products in dogs as limited, although ingredients such as L-theanine and alpha-casozepine show some potential. Supplements work best alongside environmental management, gradual desensitization and reward-based behavior modification.
A calming chew may reduce the intensity of a dog's reaction, but it will not teach a dog that fireworks, strangers or being left alone are safe. Training and management remain necessary.
How to Choose the Right Calming Chew
Choose a product that:
- Lists the active ingredients and amounts. Avoid relying only on claims such as "natural calming blend."
- Uses weight-specific dosing. The label should explain how much to give based on your dog's size.
- Matches the type of stress. Situational stress, daily nervousness and severe separation anxiety require different approaches.
- Does not duplicate ingredients in another supplement. Combining products can increase ingredients such as melatonin, tryptophan or L-theanine.
- Includes veterinary guidance when anxiety is significant. A veterinarian can check for pain, illness, medication effects or a behavioral disorder contributing to the problem.
Final Recommendation
For most dogs with predictable, mild to moderate stress, start with VetriScience Calm & Confident. Solliquin is the better fit for ongoing mild stress, Anxitane suits owners who want a simple L-theanine formula, and Quiet Moments is aimed more at nighttime restlessness. Veterinary Strength Calm & Confident is the stronger option when the standard formula is not enough.
Dogs with severe separation anxiety, panic, aggression, self-injury or repeated escape attempts need veterinary assessment rather than repeated supplement trials.
