who finally stopped dreading walks
Will it work for my kind of reactivity?
Yes. Most reactivity — doorbells, lead-lunging, pacing when you leave — traces back to the same thing: a dog whose nervous system never fully switches off.
BioPaw works on that exact underlying state. So it's less about what sets your dog off, and more about lowering the stress that makes everything set them off.
That said, the best results come alongside consistent training.
My dog's fussy, will she actually eat it?
Almost certainly. We work with a specialist pet flavour house to get the taste right, and the thing we hear most from owners is how shocked they are when their fussy dog takes them straight from the hand like their favourite treat.
If yours is one of the rare ones who won't, crumble it into her food — works exactly the same.
And if you're still unsure, don't be, because our 60-day no-questions-asked money-back guarantee has you covered.
What's the science behind it?
Dogs need 16+ hours of rest a day. A dog on high alert never gets close, and broken sleep keeps cortisol — the stress hormone behind reactive behaviour — elevated around the clock.
BioPaw supports deeper sleep, which lowers cortisol, which means less reacting.
Is it safe?
Yes. Vet formulated, third-party tested, no artificial fillers, made for daily long-term use — and it won't leave your dog drowsy.
If your dog is pregnant, nursing or under 12 weeks old, check with your vet first.
Frequently Asked Questions
How long until I see results? Most owners notice a change within 2–4 weeks of daily use. Some sooner. It's a physiological process, so consistency matters more than anything.
Will it make my dog drowsy? No. BioPaw isn't a sedative. It supports deeper sleep at night so your dog wakes properly rested, not a dog that's dopey through the day.
How many chews a day? One a day, every dog. The formula is dosed by weight, so you just pick your dog's size — and every jar is a 30-day supply.
My dog's a rescue — is she a special case? A difficult history is real, but the chronic stress that comes with it works the same way in every dog. Lowering that baseline gives her a better starting point for training and time. It doesn't erase her history — it just means she isn't fighting it exhausted.
Is it safe with my dog's current medication? Almost certainly. That said if you're worried check with your vet first as they know your dog's history best.
What if it doesn't work for my dog? Email us at hello@trybiopaw.com and we'll refund you within 24 hours. 60 days, no questions asked, and there's no need to send the jar back.
Join The Thousands of Owners Finally Meeting Their Calm Dog
Before
AfterMy 4 year old golden Murphy used to lose his MIND at every dog we passed. He's stronger than me and I was terrified one day he'd pull the lead out of my hand. 3 weeks in we passed two dogs and he just… looked at them? I actually enjoy our walks now lol
Before
AfterWe kept the curtains drawn all day because Bear freaked out at anything that walked past, delivery drivers were his mortal enemy... A month in & now when someone walks by he just lifts his head and goes back to sleep! Curtains are open again!!
Before
AfterPoppy's our jack russell rescue, scared of everything. She wouldn't leave my side for a second — even the bin lorry outside had her shaking against my leg. 6 weeks in she trotted off to say hi to another dog, tail going. There is hope.

Our 3 Steps To a Settled Dog
No dog is stuck as reactive - it's a rest problem, not a personality one. BioPaw lowers cortisol and deepens their sleep, so they wake genuinely recovered instead of constantly on edge.
1. Switch Off
Cortisol builds all day in a dog on constant alert - and the higher it climbs, the more they react. L-theanine lowers it while they're awake, so they're calmer by day and already winding down by bedtime.
2. Deeper Sleep
Dogs need 16+ hours of rest a day; reactive dogs get nowhere near it. Melatonin cues the sleep they've been fighting, valerian holds them in the deep stage - where the body clears cortisol fastest.
3. Wake Up Their Best Version
No grogginess, no sedated dog. Vitamin B1 turns yesterday's food into steady energy, so they wake as the best version of themselves - calmer, but every bit as much themselves.

Have Questions? We Have Answers.
What makes this different from other calming chews?
Most calming chews are given 30 minutes before something stressful. Ours is given every night, because it works on the sleep debt causing the behaviour rather than the reaction itself.
Will my dog actually eat these?
Almost certainly. We work with a specialist pet flavour house to get the taste right, and the thing we hear most from owners is how shocked they are when their fussy dog takes them straight from the hand like their favourite treat.
If yours is one of the rare ones who won't, crumble it into her food — works exactly the same.
And if you're still unsure, don't be, because our 60-day no-questions-asked money-back guarantee has you covered.
How long until I see results?
Most owners notice the edge coming off in the first two to three weeks. Behaviour changes tend to follow from week four.
Will it make my dog drowsy?
No. The aim is calmer, not sedated — your dog will still be fully themselves, just not constantly on edge.
What's in it, and how much?
Seven active ingredients per soft chew, all listed with their exact amounts — nothing hidden behind a "proprietary blend."
Chamomile Extract — 80 mg (Matricaria chamomilla, flower)
Hemp Seed Oil — 80 mg (Cannabis sativa, seed)
Valerian Root Powder — 50 mg (Valeriana officinalis, root)
Passion Flower Extract — 30 mg (Passiflora incarnata, aerial parts)
Vitamin B1 — 30 mg (Thiamine mononitrate)
Melatonin — 4 mg
L-Theanine — 3 mg
How do I give it, and how much?
All you do is give 2 chews each evening and your dog will think it's a treat!
Is it safe alongside medication?
Yes. But if you're still worried consult with your vet beforehand, they know your dog's history the best.
What if it doesn't work for us?
Don't stress! Even though we have less than a 0.1% return rate, we have a 60-day money back guarantee for that exact reason.
