Celery

Celery is a low calorie diet food that can also be added to your dog’s diet. They are rich in fiber, calcium, iron, potassium, vitamin A, vitamin B, vitamin K, vitamin C and vitamin D.

This veggie can boost the immune system of your dog, protect against disease, as well as improve their teeth and breath, eliminating toxins from their body. You can serve raw celery to your dog, but a light steam is also good. At just 10 calories a stalk, you can give them one a few times a week.
