If your dog likes spinach, include the green veggie in its diet. You can feed it raw by finely chopping it, steam it, or even juice it.
Spinach has a high iron content and it contains beta-carotene, which is a good antioxidant. It also contains vitamin K, which is important for healthy bones and growth.
You will sometimes see spinach on the hazardous list for dogs. That is because it contains oxalates, which can be harmful to a dog’s kidneys. However, a dog cannot eat enough spinach to cause kidney damage.
