What You Need to Know
Fresh or dried oregano in the tiny amounts found on pizza or pasta — shared accidentally — is unlikely to cause serious harm. However oregano contains carvacrol and thymol which in larger amounts cause digestive upset and have documented effects on blood sugar and clotting. Oregano essential oil is extremely concentrated and toxic to dogs even in small amounts. Never give dogs food specifically seasoned with oregano.
Breed-Specific Notes
Dogs on anticoagulant medications should avoid oregano due to blood-thinning properties.
