Antioxidant: Rosemary contains antioxidants, which help neutralize cell-damaging free radicals in the body. Rosemary’s antioxidant effects are mainly due to diterpenes, carnosol, and carnosic acid which have been linked to preventing cancer and heart disease. (Source 1/ Source 2). Natural antioxidants in dog feed, in addition to promoting feed conservation, stimulate levels of systemic antioxidants and minimize the impacts caused by free radicals in the dogs’ blood.
Antimicrobial: One of the reasons rosemary is so great as a preservative in food is the herb’s ability to keep microbes and other pathogens like bacteria and fungi at bay, which keeps the food from spoiling.

Digestion Supporter: Rosemary has been known for its ability to assist with digestion related issues due to its antimicrobial properties
Heart health: Rosemary has antispasmodic qualities on smooth muscle which may assist dogs with cardiac arrhythmia
Blood Glucose Modulation: While further studies are necessary, feeding dogs a diet with rosemary (or basil) leaves powder at 0.05% might be a promising modulator of blood glucose levels to control diabetes mellitus in dogs. (Source)
Anticancer effects: This is due to the herb’s antioxidant effects. A study in dogs noted that in combination with turmeric root, the use of rosemary induces a synergistic response to induce apoptosis. (Source)
Bug Repellant: Many owners boast about having great success when bathed in a ‘rosemary tea’. In 2020, one double-blind study, a mixture of plant-based food supplements was used to successfully treat flea infestations on dogs. Bioticks is a mixture of extracts of thyme, rosemary, melissa, fenugreek, absinthe, and lemongrass (Source). This was the first study to evaluate a plant-based product as an oral supplement for flea control. Some owners use rosemary for itchy skin on their dog.
