Rosemary for Dogs: A Complete Guide

by | Last updated Aug 31, 2026 | Herbs & Spices

For centuries, rosemary was used in Mediterranean Europe and global folk medicine for its therapeutic properties. When dogs lived primarily as working animals and scavengers, they naturally ate rosemary via table scraps, stews and roasted meats flavoured with the herb.

Historically, humans noted its benefits and utilised it for animals to help stimulate the production of bile and alleviate minor gastrointestinal bloating or wind. They also used it topically to treat irritated skin, cuts or joint inflammation and to deter fleas, ticks and mosquitoes from livestock and companion dogs.

Can dogs eat rosemary?

Yes, dogs can eat rosemary, says our in-house dog nutritionist. In fact it is a common ingredient in many commercial dog foods and treats because it acts as a natural preservative and flavour enhancer.

What are the health benefits of feeding a dog rosemary

Feeding your dog rosemary provides antioxidants, digestive support and antimicrobial benefits which can help support its immune system and overall health.

Key health benefits of rosemary for dogs include:

  • Cellular & heart protection: rosemary contains powerful antioxidants like rosmarinic and carnosic acid. These compounds neutralise free radicals, reduce oxidative stress and support cardiovascular health.
  • Digestive relief: rosemary acts as a natural antispasmodic to soothe mild stomach discomfort, reduce wind or bloating and encourage healthy gut enzymes.
  • Cognitive support: the antioxidants in rosemary help lower oxidative stress in brain cells which can help maintain mental sharpness and combat age-related dementia in older dogs.
  • Antimicrobial properties: rosemary fights off harmful bacteria, pathogens and fungi. This helps combat bad breath, support urinary tract health and protect against minor infections.
  • Natural food preservation: rosemary extract is frequently used in commercial dog food as a safe, natural alternative to controversial synthetic preservatives like BHA and BHT.

How much rosemary to feed a dog

Use a small amount of dried or fresh minced leaves a day, perhaps no more than a teaspoon of fresh chopped leaves or dried rosemary for smaller dogs up to 1 teaspoon per meal for large breeds.

Finely chopped fresh rosemary can be added to meals, broths, stews or homemade treats to provide a subtle savoury note without relying on artificial flavourings.

How to feed a dog rosemary

1. Drop a single, whole fresh sprig of rosemary into your slow-cooker when making homemade bone broth. Remove the woody stem before serving.

2. Finely chop fresh rosemary leaves to help release their natural oils and mix into your dog’s food.

3. Simmer a small sprig of fresh rosemary in water for 15-20 minutes. Once cooled, trickle the liquid over your dog’s food as a flavour enhancer.

4. Incorporate a small amount of rosemary into homemade treats.

5. Incorporate it into your dog’s homemade meals together with other dog-safe herbs and spices.

Note: avoid rosemary in all forms if your dog has epilepsy or a history of seizures as high doses or concentrated extracts may trigger episodes. Do not feed rosemary to pregnant dogs.
