SAFE
A tiny amount of oregano is safe for dogs. Large amounts can irritate the stomach.
What to do
Use only tiny amounts and avoid essential oil.
When to contact a vet: Contact a vet if your dog ate oregano essential oil or a large amount.
Symptoms to look for
- vomiting
- diarrhoea
- stomach irritation
Why
Oregano is not toxic to dogs in small amounts. It has antimicrobial properties but can cause stomach upset if a dog eats a large amount of fresh or dried herb. Oregano essential oil is concentrated and should be avoided.

Dogs can react differently depending on their size, age, health, allergies, medications, the amount consumed and other circumstances. An item classified as Safe is not necessarily suitable for every individual dog.
If your dog has eaten something potentially poisonous or dangerous, has eaten an unknown substance, or is showing concerning symptoms, contact your veterinarian or an emergency veterinary service immediately.
Do not induce vomiting or give your dog medication unless specifically instructed to do so by a veterinary professional.
