Rosemary
Dogs may encounter rosemary as an environmental allergen or ingest it via food.
Rosemary extract is frequently added to commercial dog food because it acts as a natural antioxidant and preservative.
It may also be added to commercially produced ground turkey meat due to its ability to slow pigment oxidization. It can also be found in various health & beauty products, oil diffusers, scented plug-ins, and household cleaners so be sure to check ingredients thoroughly.
