Did you know?
Kale was the most widely consumed green vegetable in Europe throughout the Middle Ages because it was extremely cold hardy — it could be harvested even after frost. The term borecole for kale comes from the Dutch for peasant cabbage reflecting its status as common people's food. Its recent superfood status represents a complete reversal from its humble peasant origins.

What You Need to Know
Kale contains isothiocyanates which in large amounts cause gastrointestinal irritation and may affect thyroid function. It also contains oxalic acid. Small occasional amounts as a food topper are not harmful for healthy dogs. Regular large amounts are problematic. Raw kale is harder to digest than cooked kale.
