Short answer

If it's a small amount, he should be fine. Monitor for any signs of stomach upset. If he's vomiting or has diarrhea, call your vet. They'll check for kidney issues. No need to rush to the vet unless symptoms persist.

Kale — Food safety facts

Safe in small amounts, steamed is gentler. Contains calcium oxalates — skip if your pet has kidney issues.

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

Kale 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.

Why these cautions matter

Caffeine overstimulates the heart and nervous system, and pets clear it so slowly that tremors and restlessness drag on far longer than they would in a person.

Kale can stay on the rotation, but only as an extra mouthful: keep the rest of the day's food unchanged and watch the next walk and the stool that comes with it.
