Supplementing a dog's diet with coconut oil helps improve the dog's digestion, increase nutrient absorption and contribute to healthy skin and a shiny coat, according to DogsNaturally. The medium chain triglycerides have antifungal, antiviral and antibacterial properties that can support a healthy immune system.
Additional benefits of adding coconut oil to a dog's diet include reducing bad breath, minimizing allergic reactions and alleviating some of the discomfort associated with arthritis. Apply the oil topically to speed wound healing and to moisturize dry skin. DogsNaturally recommends giving coconut oil to dogs twice daily at a dosage of 1/4 teaspoon of coconut oil for every 10 pounds of a dog's body weight.
