Ginger for nausea and vomiting (dog)
Ginger in dogs: honest evidence overview (grade C), safety and interactions for nausea and vomiting.
Short & honest
Ginger has limited evidence (grade C) for nausea in dogs: one animal study, no clinical RCTs. Safe at low doses, but always consult a vet.
Safety assessment: Safe when used correctly

What is ginger?
Ginger (Zingiber officinale) is a rhizome that has been used in traditional medicine for centuries, among other things for nausea and stomach complaints. The active constituents — gingerols and shogaols — are assumed to act on the gastrointestinal tract and on the vomiting centre in the brainstem [2].
Claims versus evidence
In humans, there is reasonable evidence that ginger relieves nausea, particularly in pregnancy-related vomiting and chemotherapy-related complaints. In dogs, the evidence is considerably thinner.
One animal study [1] investigated the anti-emetic effect of ginger in dogs receiving cisplatin (a chemotherapy agent). The results suggested an inhibitory effect on vomiting. However, this concerns a single study from 1997 with methodological limitations and without controlled clinical follow-up in the practice population.
Clinical practice monographs recognise ginger as potentially useful for mild nausea, motion sickness or stomach complaints in dogs, but emphasise that the evidence remains limited and that use should occur in consultation with a veterinary surgeon [2].
Evidence grade C — there is biological plausibility and some animal study confirmation, but no clinical randomised research demonstrating efficacy in companion animals.
Safety
Ginger is generally considered safe in dogs at low doses [2]. Known points of attention:
- Gastrointestinal irritation: Higher doses can actually cause nausea, diarrhoea or stomach pain — the opposite of the intended effect [2].
- Blood coagulation: Ginger has mild blood-thinning properties, relevant in dogs using anticoagulants or having a coagulation disorder [2].
- Blood sugar: In combination with diabetes medication, ginger can affect blood sugar levels [2].
- Species-specific sensitivity: Dogs metabolise plant substances differently than humans. What is safe in humans is not by definition safe in dogs.
Concrete dosages fall outside the scope of this page. Always consult your veterinary surgeon about dosage and applicability for your specific dog.
When not to use without veterinary consultation
| Situation | Reason |
|---|---|
| Use of blood thinners or NSAIDs | Increased bleeding risk |
| Diabetes or insulin use | Risk of blood sugar fluctuations |
| Around surgeries | Disrupted blood coagulation |
| Puppies younger than 6 months | Insufficient safety data |
What vomiting in a dog can mean
Vomiting has a broad spectrum of causes, ranging from harmless (eating too fast, eating grass) to serious (poisoning, intestinal obstruction, organ failure). Ginger is not a replacement for veterinary diagnosis. Never administer a remedy — including an herb — without understanding why a dog is vomiting.

Why this verdict?
The evidence for ginger in dogs is based on one animal study from 1997 that demonstrated an anti-emetic effect in cisplatin-induced vomiting [1], supplemented by clinical practice monographs [2]. No randomised clinical trials have been conducted in companion animals; the only animal study has methodological limitations, and dose-response data are lacking. This results in evidence grade C: biological plausibility and some animal study confirmation, but insufficient clinical evidence to substantiate efficacy.
Interactions with medication
- Anticoagulants (e.g. warfarin, heparin): increased bleeding risk due to mild blood-thinning effect of ginger [2]
- NSAIDs (e.g. meloxicam, carprofen): possible interaction affecting blood clotting [2]
- Insulin and oral diabetes medication: risk of blood sugar fluctuations [2]
