About the product
What is Ventra® Gut Cleanse Drops?
It is a liquid food supplement for dogs — a 21-day course of botanicals combined with a four-strain postbiotic blend, designed to support your dog's gut. It is given by mouth, over food or in water, once a day.
Is it a medicine or a dewormer?
No. Ventra® is a food supplement, not a medicine, and in the European Union it is sold as complementary feed for pets. It is not intended to diagnose, treat, cure or prevent any disease, and it is not a substitute for veterinary advice, diagnosis or treatment. If your dog is unwell or you suspect a specific problem, speak to your veterinarian.
What is in it?
Black walnut hull, wormwood root, Oregon grape root, clove, pumpkin seed, ginger, fennel, marshmallow, goldenrod and olive leaf, together with a postbiotic blend of four strains. The full ingredient list and amounts are shown on the product page and on the bottle label.
Why liquid instead of a chew?
A liquid contains no flour, fat or binder that has to be broken down first. It mixes straight into food or water, and it makes the dose easy to adjust to your dog's weight.
Giving it to your dog
How much do I give?
Shake the bottle well, then give once a day over food or in water:
- Under 10 lb (under 4.5 kg) — ½ pipette (0.5 ml)
- 10–35 lb (4.5–16 kg) — 1 pipette (1 ml)
- 35–75 lb (16–34 kg) — 2 pipettes (2 ml)
- Over 75 lb (over 34 kg) — 3 pipettes (3 ml)
Give the full daily dose for 21 days, then move to maintenance — or follow whatever your veterinarian advises.
Will my dog take it?
The drops are duck flavoured and most dogs take them without fuss. If your dog is fussy, mix the dose through a wet meal rather than sprinkling it on top.
How long does one bottle last?
One bottle is a full 21-day course at the standard dose for a medium dog. A larger dog on a higher dose will finish a bottle sooner, and a small dog will make it last longer.
When will I see a difference?
Most owners tell us they notice the first change somewhere in week 2 to 3. The first week is usually quiet on the outside. Results vary from dog to dog, and we do not promise a particular outcome for your animal.
What do I do after the 21 days?
Most owners move to a lower maintenance dose a few times a week. If you are unsure what suits your dog, ask your veterinarian.
Is it safe for my dog?
It is formulated for dogs of all breeds from 12 weeks of age, and the wormwood is standardised to a maximum of 0.85% thujone.
Talk to your veterinarian before you start if your dog is on medication, is pregnant or nursing, has a diagnosed medical condition, or is due for surgery.
What if my dog reacts badly?
Stop giving the drops and contact your veterinarian. Then email us at help@ventra.pet — we want to know, and your order is covered by our guarantee.
Can I give it alongside other food or supplements?
It is given with food and is generally used alongside a normal diet. If your dog already takes another supplement or any medication, check with your veterinarian first.
How should I store it?
Keep the bottle closed at room temperature, out of direct sunlight, and out of reach of children and pets. No refrigeration is needed.
Ordering and delivery
Where do you ship?
The United States, the Netherlands and Poland. Prices are shown in your local currency — USD, EUR or PLN — based on your delivery country.
What does shipping cost?
A flat $7.90 per order, and free on orders of $35 or more. In the Netherlands and Poland this is charged in your local currency, and the exact amount is always shown at checkout before you pay.
How long will my order take?
Orders are dispatched within 1–4 business days, and delivery takes a further 6–10 business days — roughly 7 to 14 business days in total. Orders placed after 5:00 PM UTC, or at a weekend or public holiday, start processing on the next business day. Full detail is in our Shipping policy.
Can I track my order?
Yes. Every order ships with tracking, and you will get a dispatch email with your tracking number and link. Tracking can take up to 48 hours after dispatch to start updating, which is normal. You can also check on our Track your order page.
Will I pay customs or import charges on delivery?
No. All applicable taxes, duties and import charges are calculated and collected at checkout, so the total you see is the total you pay. If a carrier ever asks you for an extra charge on delivery, email us and we will resolve it and reimburse you.
Can I change my address or cancel my order?
Yes, as long as it has not shipped yet. Email help@ventra.pet with your order number as soon as you can. Cancelling before dispatch costs you nothing.
My order has not arrived. What now?
If tracking has not moved for 10 business days, or your order is more than 10 business days past its estimated delivery date, contact us. We will chase the carrier for you, and if a parcel is confirmed lost we replace it or refund it in full.
Returns, refunds and the guarantee
How does the 90-day money-back guarantee work?
If you do not see a difference in your dog, email us within 90 days of delivery and we refund that order — even if the bottle is empty. It applies to your first order, one claim per customer or household. You return the bottle so we can close the claim, and return postage for a guarantee claim is paid by you. Full terms are in our Refund policy.
Can I return a bottle I have not opened?
Yes — within 30 days of delivery, unopened and with the seal intact, no reason needed. Because the drops are a consumable taken by an animal, opened bottles cannot be resold and are not eligible for an ordinary return; that is exactly what the 90-day guarantee is for.
Who pays return postage?
You do, for ordinary returns and for guarantee claims. We pay in full whenever an item arrives faulty, damaged or is not what you ordered.
How long does a refund take?
We refund within 7 business days of receiving and inspecting your return, to your original payment method. Your bank may then take a further 3–10 business days to show it.
I am in the Netherlands or Poland — do I have extra rights?
Yes. You have a statutory 14-day right of withdrawal from the day you receive your order, without giving a reason. That right sits on top of our 30-day return window and 90-day guarantee — it does not replace them.
Do you do exchanges?
Not directly. Return the original for a refund and place a new order — it is faster.
Payment
How can I pay?
Visa, Mastercard, American Express and other major cards, plus Apple Pay, Google Pay and Klarna where available. Customers in Poland can also pay with BLIK and Przelewy24. What you can actually use is always shown at checkout.
Is paying on your site secure?
Yes. Payments are processed by Stripe and our payment processing is certified to PCI DSS Level 1. We never see or store your full card number, and the whole site runs over SSL/TLS encryption. See our Payment policy.
Are there any hidden fees?
None. No handling, packaging, transaction or service fees. The total shown before you confirm is the full amount payable to us. Your own bank may charge separately for a foreign transaction or currency conversion — that is set by them, not us.
Why was my payment declined?
Your bank can see the reason and we cannot, so check with them or try another method. You are never charged for a payment that fails. A temporary hold sometimes appears on a declined order; it is not a charge and your bank releases it automatically.
Still need help?
Email help@ventra.pet with your order number and we will come back to you within 1–2 business days. We answer email Monday to Friday, excluding public holidays.
