“Three thunderstorms in, she stays on her bed.
Elsa V. · verified buyer · ★★★★★Real owners, real change.
A selection of recent verified reviews from the 286 owners using Calm & Relax today.
We're on our third thunderstorm since starting, and she's stayed on her bed the whole time. Previously? Panting in the closet for hours. Massive quality-of-life improvement for her — and us.
Made for the dog who can't quite settle.
If any of these sound familiar, your dog is exactly who we built Calm & Relax for.
- Whining and pacing when left alone
- Cowering or hiding during fireworks
- Triggered by doorbells, strangers, passing dogs
- Restless evenings — can't switch off
- Trembling on car rides or at the vet
- Easier solo time and softer goodbyes
- More composed during noise and storms
- Less reactive to everyday triggers
- Settles on their own, finds their off switch
- Travels and waits with less stress
A formula we wanted for our own dogs.
Petnuvia started in a small lab outside Stockholm, when we couldn't find a calming chew we'd actually feel good about giving our own dogs. Most options on the market were over-promised, under-dosed, or quietly stuffed with fillers we didn't recognize.
Six active ingredients, each chosen for documented effects in canine wellness. Manufactured in the EU under GMP+ standards. No soy, no sugar, no synthetic colors. Just a daily chew dogs love and we trust.
Each ingredient earns its place.
Six actives, chosen for documented roles in canine wellness — sourced and dosed with care, not as marketing dust.
Valerian rootValeriana officinalis
Studied for its role in supporting relaxation and a gentler nervous system response.
Lemon balmMelissa officinalis
Traditional botanical recognized for its calming properties in mammals.
L-TryptophanEssential amino acid
Precursor to serotonin, involved in the body's natural pathway for mood regulation.
L-TheanineFrom green tea extract
Amino acid studied for promoting a relaxed but alert state — not drowsy.
Magnesium glycinateBioavailable form
A highly absorbable mineral involved in muscle and nervous system function.
Ashwagandha rootWithania somnifera
Adaptogen with a long history of supporting the body's response to stress.
Backed by peer-reviewed research.
In a peer-reviewed study of 13,700 dogs (Salonen et al., 2020, Scientific Reports, Nature), 72.5% displayed at least one anxiety-related trait — 32% noise sensitivity, 29% general fearfulness, and 17% fear of strangers or other dogs.
Calm & Relax is built around actives chosen from that body of research — L-tryptophan (Araujo et al., 2010), valerian root (Sage et al., 2016), L-theanine (Dramard et al., 2018), and ashwagandha (Bharani, 2024) — selected for their documented role in supporting emotional balance, without sedation.
Published ingredient research
Every active is selected from peer-reviewed veterinary and nutritional studies — including a 13,700-dog anxiety study (Salonen et al., 2020).
Product-level quality standards
Manufactured in the EU under GMP+ standards, clean-label and batch-controlled — no fillers, soy, sugar, or artificial colors.
Veterinary-informed formulation
Forms and doses are chosen with veterinary input — bioavailable magnesium glycinate over oxide, real extracts over flavoring.

Comparison reflects typical category formulations, not any specific brand.
Formulated with veterinary input.
What sets Petnuvia apart is the willingness to pick the form of an ingredient that actually gets absorbed — magnesium glycinate over oxide, real lemon balm extract over flavoring. It's the kind of formulation choice owners often can't see, but their dogs do.
Try it for 60 days. Risk-free.
Your dog has the last word. If you don't see the change you were hoping for, we'll refund you — no return shipping, no awkward questions.
Things owners ask.
How long until I see results?
Most owners notice the first softer reactions within 2–3 weeks of daily use. The fuller benefit typically becomes clear around week 8. Calm & Relax is built for gentle, gradual support — not an instant fix.
Can I give Calm & Relax alongside other supplements?
In most cases, yes — the actives in Calm & Relax are recognized for canine wellness and are commonly combined with joint, skin, or digestive supplements. If your dog is on prescribed medication, we recommend checking with your vet first.
Is it safe for puppies, senior dogs, or pregnant dogs?
Calm & Relax is formulated for adult dogs. For puppies under 12 months, senior dogs with underlying conditions, or pregnant or nursing dogs, please consult your veterinarian before starting.
Will it make my dog drowsy?
No. Calm & Relax is not a sedative. It supports the body's own pathways for a calmer state — your dog stays themselves, just less reactive.
What if my dog refuses the chew?
Our soft chew is highly palatable and dogs typically accept it as a treat. If yours doesn't, our 60-day guarantee covers it — just reach out and we'll make it right.
Can I use it situationally — fireworks, vet visits?
Calm & Relax is designed for daily use to build steady-state support. For acute moments, owners often increase to the next dose size on the day of the event. It works best when given consistently for several weeks first.
Why should I give my dog Petnuvia supplements?
We all want the best for our best friends. Our Petnuvia chews are formulated with beneficial ingredients chosen from published research to help support your dog's everyday health — especially when given consistently. Best of all, they taste great, so your dog will love them too.
How old should my dog be?
We recommend introducing the chews once your dog reaches six months of age. If you have any concerns, please contact your vet.
Where is your product made and what are its credentials?
Our chews are made in the EU under GMP+ certified manufacturing standards. We work closely with our manufacturer to ensure only high-quality ingredients are used.
