Can Dogs Eat Kale? Caution — Safe in Small Amounts, More Caveats Than Other Vegetables
This food requires caution. Read the details carefully before feeding.
Plain kale is safe for dogs in small amounts but is one of the more controversial dog vegetables. Contains calcium oxalates (kidney stone risk with excessive feeding), isothiocyanates, and goitrogens. Small amounts occasionally are not harmful for healthy dogs.

Did you know?
Kale was the most widely consumed leafy vegetable in Europe during the Middle Ages — it was easier to grow in cold climates than lettuce and more cold-hardy than other vegetables. Kale can survive temperatures down to -15°C making it a winter crop when little else grew. Its popularity declined with the introduction of other vegetables from the Americas and it remained primarily cattle fodder for centuries before being rediscovered as a health food in the early 2000s. The kale marketing boom of 2012-2014 increased US kale production by over 60%.

What You Need to Know
Kale has been heavily promoted as a superfood but its benefits for dogs come with more caveats than simpler vegetables. The calcium oxalate content raises concerns for dogs prone to kidney stones. The isothiocyanates cause digestive upset like other cruciferous vegetables. The goitrogens affect thyroid function in excess. Small amounts occasionally for healthy dogs without kidney issues are not harmful. Broccoli or green beans are simpler safer alternatives.
Breed-Specific Notes
Avoid in dogs prone to calcium oxalate kidney stones.
