Fireworks, thunderstorms, car rides and vet visits can turn a relaxed dog into a trembling one. Over-the-counter calming chews from VetIQ and NaturVet are among the most widely sold options at pet stores, and both combine ingredients such as chamomile, L-tryptophan and thiamine. The formulas look similar at a glance, but the amounts per chew, the presence of melatonin and the extra ingredients differ. This comparison uses the brands’ published labels. Calming chews are supplements, not medications, so discuss them with your vet, especially for dogs with severe anxiety or other health conditions.

What calming supplements can and cannot do
Mild situational stress may respond to supplements plus behavior strategies. Evidence for individual ingredients like L-theanine, L-tryptophan and chamomile in dogs is limited but generally points to modest effects at best. Severe noise phobia, separation anxiety with destruction or self-injury, or aggression usually need a veterinary behavior plan and sometimes prescription medication. A supplement should never replace that conversation.

Key differences explained
Melatonin
Per single chew, the newer VetIQ formula contains considerably more melatonin than a single NaturVet chew. Melatonin may help with sleep and some noise-related stress. It can interact with other medications and is not appropriate for every dog; ask your vet if your dog is pregnant, diabetic, on medication or very young.
L-theanine versus ginger
VetIQ adds L-theanine, an amino acid often included in calming products. NaturVet adds ginger, which may be helpful for dogs whose travel stress comes with an upset stomach.
Herbal amounts
NaturVet lists higher totals of chamomile and passionflower, though its label is per two chews, so compare per-dose amounts at your dog’s weight band.
Dosing and timing
Both labels give chew counts by body weight. NaturVet’s label suggests giving the dose about 30 minutes before a stressful event and specifies use in dogs over 12 weeks. Follow the label for your dog’s weight and do not combine multiple calming products without veterinary guidance. Do a trial run on a calm day to check your dog’s reaction before relying on the chew during fireworks.
Pair supplements with behavior strategies
- Create a safe den: a covered crate or quiet room with familiar bedding.
- Use white noise or music to mask thunder and fireworks.
- Practice counter-conditioning: pair low-volume recordings of triggers with treats over weeks.
- Consider a snug-fitting pressure wrap for some dogs.
- Avoid punishing fearful behavior; it tends to worsen anxiety.
Cost comparison
Both brands are budget friendly. Expect roughly $0.15 to $0.40 per chew depending on pack size and retailer. Because doses scale with weight, a large dog’s cost per event can be several times a small dog’s.
When to see your vet
Contact your vet if your dog’s anxiety is escalating, causing injury or destruction, or affecting eating and sleep. Also call if a dog becomes unusually sleepy, uncoordinated, or has vomiting or diarrhea after a calming chew. Sudden anxiety in a senior dog can also be linked to pain or cognitive changes, which deserve an exam.
Choosing between them
- Noise events like storms or fireworks: either product per label, given ahead of time, combined with a safe den and sound masking.
- Car rides with an upset stomach: NaturVet’s ginger may be a better fit; ask your vet about motion sickness medication if vomiting is frequent.
- Dog that already takes melatonin or other medications: talk to your vet before adding either chew.
- Picky eater: try a small pack of each; flavor preference often decides.
FAQ
Which is stronger, VetIQ or NaturVet?
It depends on the ingredient. Per chew, the newer VetIQ formula has more melatonin; NaturVet lists more chamomile and passionflower per labeled dose and adds ginger. Neither is a sedative.
Can I give calming chews every day?
Both brands describe daily or situational use per label directions. For ongoing anxiety, ask your vet about a long-term plan rather than relying only on supplements.
Bottom line
VetIQ Calming Support (newer label) offers more melatonin per chew plus L-theanine, while NaturVet Quiet Moments combines higher herbal amounts with ginger for travel-related tummy upset. Both are affordable, label-dosed supplements for mild, situational stress. Use them alongside behavior strategies, and see your vet for severe or worsening anxiety.
