Can dogs eat rosemary?

Rosemary's needle-like leaves are tough, so chop them finely before adding a pinch to food. For a medium dog, a quarter of a teaspoon of chopped fresh rosemary is enough. Dried rosemary is stronger, so use even less.

Rosemary sprigs and woody stems are hard and sharp enough to scratch the mouth or throat if swallowed.

You may see rosemary extract on the ingredient list of your dog's food. It is used in small, measured amounts as an antioxidant to stop fats going rancid. This is safe and well established. It does not mean extra rosemary at home adds any benefit.

Rosemary bushes are common along paths and borders. Dogs brushing past them pick up the scent on their coats, which is harmless. Chewing on branches can cause scratches or mild stomach upset from the woody stems. Rosemary is also a useful plant for dog-friendly gardens because it tolerates dry soil and does not attract heavy pesticide use.

Some vets advise caution with rosemary for dogs that have epilepsy, because concentrated rosemary contains compounds thought to affect the nervous system. The evidence mainly concerns essential oils rather than a pinch of herb, but if your dog has seizures, ask your vet before adding rosemary.

Roast lamb, roast potatoes, focaccia and chicken seasoned with rosemary nearly always include garlic, and often salt and oil. The rosemary is not the problem; the company it keeps is. Set aside plain food before seasoning.
