Every dog is different. Individual allergies and sensitivities are common — always introduce new foods in small amounts and watch for adverse reactions. This site is for informational purposes only and is not veterinary advice. Always consult your vet.
The Full Picture
Kale is technically safe for dogs in small amounts and offers vitamins A, C, and K, plus iron and calcium. However, it contains calcium oxalate (which can contribute to kidney and bladder stones) and isothiocyanates (which can cause gastric irritation). For dogs with kidney problems, kale should be avoided entirely. For healthy dogs, occasional small portions of cooked, plain kale are fine, but there are better vegetable options like green beans or carrots.
What You Should Know
While kale is not outright toxic, there are important precautions to bear in mind before sharing it with your dog. Portion size matters, and certain preparations or varieties may be unsafe. If your dog has any existing health conditions, check with your vet first.
