Do you know this feeling?

Your dog is trembling, barking, panting. You feel powerless.

Fear, stress, and hyperactivity make everyday life a burden — for your dog and for you. You don't have to resort to chemical sedatives.

Panic during thunderstorms & New Year's Eve

Shaking, panting, hiding under the bed. You'd do anything to take away his fear—but nothing helps.

Separation anxiety is tearing you apart

You can't even leave the house for a moment without him crying, scratching, tearing everything apart. The neighbors are complaining. You feel trapped.

Sedatives turn him into a zombie

Acepromazine, Trazodone, Gabapentin — he's calm but absent. That's not your dog. You want relaxation, not a sedative.

Endless hyperactivity

He never settles down. Barks at every sound. Reacts to every stimulus. You can't relax — and neither can he.

The solution

It also works without sedatives.

Advanced Calming Bites combine clinically researched Suntheanine® L-Theanine with Ashwagandha, Melatonin, and soothing herbs — for genuine relaxation without sedating your dog or changing their personality.

The science behind it

How Advanced Calming Bites works.

01

Activate alpha waves

Suntheanine® L-Theanine increases alpha brain waves — the same state dogs have in deep relaxation. Calms without sedating.

02

Regulate stress hormones

Ashwagandha is a clinically researched adaptogen that dampens the cortisol response to stress stimuli — your dog remains calmer during thunderstorms, noise, and separation.

03

Gentle sleep-wake rhythm

Melatonin, valerian, L-tryptophan, and chamomile support a natural sleep rhythm — without the abrupt 'knockout effect' of sedatives.

First New Year's Eve without shaking!

Every New Year's Eve, Luna would hide under the bed, trembling and panting—it was heartbreaking. This year, 1 hour beforehand, I gave her 2 chews, and she lay relaxed next to me on the sofa. I couldn't believe it. Finally.

Car rides without drool drama

Leni always drooled, trembled, and whined in the car. A chew 45 minutes before the ride — she's now lying quietly in the back seat. Sounds like an advertisement, but it's really true.

Skeptical — and pleasantly surprised

I had already tried 3 other 'calming' products, all failures. Balu reacts to thunderstorms with total panic. With the Calming Bites, he is noticeably more relaxed — he still pants a bit, but no more trembling, no more hiding.

Finally calm at the vet

Frida turned every vet visit into a thriller. With the chews 1 hour beforehand: calm on the table, lets herself be touched, no more attempts to bite. The vet even thanked me.

He's not 'stoned' — just calmer

What I find most important: Rocky is not absent or sluggish like he was with Trazodone. He's simply more relaxed. He plays normally, reacts normally — he just doesn't bark at every sound anymore. Exactly what I wanted.

Works — but the dosage has to be right

For Emma, 1 chew wasn't enough; with 2, it works reliably. One star deducted because you have to experiment a bit at the beginning. But then it really works.

Stop Trazodone

We finally wanted to get Bruno off Trazodone. In consultation with the vet, we switched to Calming Bites — it's been going well for 2 months. He's "back" but calm.

Barking at guests almost gone

Lotte used to bark for 5 minutes every time the doorbell rang. With the chews, she barks 1–2 times briefly and then calms down. The change became noticeable after about 10 days.

Senior finally sleeps through the night

Carlo (11) used to walk around and whine all night. Since he started taking the chews, he's been sleeping through the night again. So have I. Definitely recommended, especially for older dogs with restlessness.

Puppy finally getting tired

Kira is 8 months old and full of energy — she could never settle down in the evenings. With 1 chew after dinner, she relaxes and falls asleep peacefully. A lifesaver.

Thunderstorm season saved

Maja used to tremble all summer with every thunderclap. Having given her the chews preventively when the weather changed — she's much calmer now. Walks are possible again.

It works, but it's no miracle cure

Realistic: it's calming, not sedating. It's not enough on its own for extreme anxiety — but noticeably better combined with training. Fair 4 stars.

FAQ

Everything you need to know.

For acute situations (thunderstorms, New Year's Eve, car rides, vet visits), administer the chews 30–60 minutes before the triggering event—they take effect within approximately 45 minutes. For chronic anxiety and separation anxiety, the full effect develops after 1–2 weeks of daily use, as the stress hormone system and sleep rhythm need time to adjust.

No. This is precisely the crucial difference from sedatives like trazodone, acepromazine, or gabapentin. Suntheanine® L-Theanine promotes calm alertness — your dog is relaxed but present. He plays, responds, eats, and participates in life — just more calmly. No unsteady gait, no apathy.

Yes, completely harmless. All ingredients are natural and safe for long-term daily use. For chronically anxious dogs, dogs with separation anxiety, or hyperactive puppies, daily administration is even recommended, as the calming effect only fully develops over several weeks.

Small Dogs (up to 11 kg): 1 Chew  ·  Medium Dogs (12–34 kg): 2 Chews  ·  Large Dogs (over 34 kg): 3 Chews. Start with half the amount and gradually increase. The daily amount can be divided between morning & evening. For acute stress: 30–60 minutes before the event.

Suntheanine® is the patented, clinically researched form of L-theanine — the relaxing amino acid found in green tea. It increases alpha brain waves and measurably reduces stress markers without causing sedation. Unlike regular L-theanine, Suntheanine® is purity-tested and has been validated in multiple clinical studies (including in dogs).

Then we will refund you the full purchase price — guaranteed. Our guarantee is valid for 30 days from the delivery date, provided the product is used correctly. If your dog does not show a visible improvement after this period (calmer behavior, better sleep, fewer stress reactions), simply send us a short email. No returns, no forms, no stress — not for you either.

Our promise

Try it for 30 days. Completely risk-free.

You've taken enough risks already — this one's on us. If your dog isn't noticeably calmer and more balanced after 30 days of daily use, you get every cent back — even if the jar is already half empty. No returns, no forms.
