My 12-year-old, 5 kg diabetic dog is on heart medication — is cooked kohlrabi still okay as a treat?

Short answer

Yes, it is fine. Kohlrabi is non-toxic to dogs and does not interact with heart or diabetes medications. Peel it, cook it thoroughly, cut it into small pieces, and offer only a tiny amount to your small senior dog. Watch for any tummy upset after feeding, and call your own vet if anything seems off.

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.
