Batch note: small-batch botanicals
Each run is limited by our wormwood and black walnut harvest. The last three batches sold through in under 11 days. If you're planning a cleanse, we'd grab it now rather than wait on the next pour.
Milo had been scooting across the rug for weeks and his coat looked like straw. Our vet ruled out the obvious stuff and suggested we look at his gut. I started the drops on a Monday — he licked them straight off the kibble, no fight at all. Week two the scooting stopped. By the end of the 21 days his coat had actual shine again and he'd stopped chewing at his back end. Third bottle on the way.
What it is
+
Vesterial Parasite Cleanse Drops are a liquid herbal blend for dogs, built around the three botanicals traditionally used together for gut cleansing — black walnut hull, wormwood and Oregon grape root — supported by seven more soothing and carminative herbs.
We added a four-strain postbiotic blend because a cleanse is only half the job. Clearing the gut and then leaving it bare is how dogs end up with loose stools. The postbiotics help the good bacteria hold their ground while the botanicals work.
60 servings per bottle. One dropper a day. That's a full 21-day cleanse with room to spare.
What you might notice
+
✓ Supports normal intestinal balance
✓ Helps maintain a healthy gut environment
✓ Supports normal digestion and stool consistency
✓ Supports skin and coat condition from the inside out
✓ Helps maintain normal comfort around the rear end
Every dog is different. Most owners tell us the first change they spot is around the end of week two.
How to give it
+
Shake well, then dose once daily by weight:
Under 25 lbs — half a dropper (0.5 mL)
25–60 lbs — one full dropper (1 mL)
Over 60 lbs — one and a half droppers (1.5 mL)
Squeeze it straight over food. It's duck-flavoured, so most dogs treat it as a bonus rather than a medicine. Run it for 21 days, then take a week off.

Guarantee & safety

Every order is covered by our 60-day Happy Dog Guarantee. Finish the cleanse, and if you're not glad you did, email us and we'll refund you — bottle included.
Not for puppies under 12 weeks, or for pregnant or nursing dogs. Wormwood is a potent herb; if your dog is on medication, has a seizure history, or has liver or kidney concerns, talk to your vet before starting. This is a supplement, not a dewormer and not a substitute for veterinary diagnosis or treatment.

1Shake the bottle
Botanical extracts settle. Give it a firm five-second shake so every dropper is as strong as the last.

2Dose by weight
Half a dropper under 25 lbs, a full dropper for 25–60 lbs, one and a half above that. Squeeze it straight over their food.

3Serve and repeat for 21 days
It's duck-flavoured, so there's nothing to hide and nothing to fight. Once a day for three weeks, then rest a week.
What's inside
Ten botanicals, four postbiotic strains, nothing to pad the bottle.
The cleansing work is led by black walnut hull, wormwood and Oregon grape root — the trio herbalists have paired for generations. Around them sit seven supporting herbs chosen to keep the process gentle: marshmallow root and slippery ginger to soothe, fennel for wind, clove and olive leaf to back up the blend, pumpkin seed and goldenrod to round it out.
Then the part most cleanses skip. A four-strain postbiotic blend rides along for all 21 days, so the gut isn't left bare once the botanicals have done their work.
- No fillers
- No artificial flavour
- No grain, corn or soy
- Natural duck flavour

The questions we actually get asked.
Still unsure? Message us — bottom right corner, real humans.
Is this safe for my dog?
+
For healthy adult dogs, yes — used at the weight-based dose on the bottle. Wormwood is a genuinely potent herb, which is why we cap thujone at 0.85% and print it on the label. Skip it for puppies under 12 weeks and for pregnant or nursing dogs. If your dog is on medication, has a seizure history, or has liver or kidney concerns, check with your vet first.
Is this a dewormer?
+
No. Vesterial is a herbal supplement that supports normal intestinal balance — it is not a veterinary medicine and does not replace prescription deworming or a vet's diagnosis. If you suspect a specific infestation, see your vet. Plenty of owners use us alongside their vet's plan; ask yours if that fits your dog.
My dog is impossibly fussy. Will they take it?
+
Almost certainly. It's a duck-flavoured liquid, not a tablet — you squeeze it over food and it disappears into the bowl. 94% of surveyed owners said their dog took it with no fuss at all. If yours is the exception, the guarantee has you covered.
What if their stools go loose at the start?
+
Some dogs pass softer stools in the first few days as things shift. It typically settles within a week, and the postbiotic blend is in there specifically to smooth that transition. If it's severe or lasts beyond a week, stop and speak to your vet.
How often should we run a cleanse?
+
Twenty-one days on, then a week off. Most owners repeat it once a quarter — more often after kennel stays, heavy dog-park seasons or a summer spent in long grass. A single bottle holds 60 servings, so one cleanse leaves you with spare.
Shipping and returns?
+
US orders ship in 1–2 business days, with free shipping over $60 and on every multi-bottle order. Delivery is typically 3–7 business days. Everything is covered by the 60-day Happy Dog Guarantee — opened bottles included.
