My 12-year-old dog weighing 38 pounds has chronic kidney disease — is it safe to give him small pieces of peeled cooked kohlrabi twice a week?

Short answer

Yes, small amounts of peeled cooked kohlrabi are safe for your dog even with kidney disease. Kohlrabi is non-toxic and contains fiber and vitamin C, but it should always be cooked and served plain without salt, butter, or seasonings. Because of his kidney condition, introduce it very slowly and monitor his urine output and appetite closely. If he develops diarrhea, vomiting, or seems less interested in his regular food, stop offering it and call your veterinarian.

Kohlrabi — Food safety facts

Peeled and cooked in small pieces.

Dogs and cats carry the same rating (Safe to share), so the notes below hold for either pet.

Kohlrabi is not toxic to dogs. The real limit is calories, fat and salt, so treat it as a small extra alongside the normal ration rather than a meal in itself.

There is no poisoning risk here, and the usual problem is simply eating too much at once: a heavy fat or salt load can bring on loose stools or a single vomit. Offer water, keep an eye on the pet for 24 hours, and do not induce vomiting.
