Can dogs eat Kale?
In small amounts, with care
In moderation - a little cooked kale will not hurt a healthy dog, but it is high in oxalates and best avoided entirely if your dog has kidney or bladder stone history.

What happens
Kale is genuinely nutrient-dense, with plenty of vitamins A, C and K plus fibre, and a small amount is harmless to most dogs. It sits in the caution column for two reasons rather than one. The first is oxalates, which bind calcium and, in quantity or over time, may contribute to calcium oxalate stones in dogs already prone to them. The second is a group of compounds called isothiocyanates, which are what give brassicas their bite; in large amounts they irritate the gut and cause quite dramatic wind. Neither makes kale dangerous for a healthy dog eating a spoonful now and then, but neither is a reason to treat it as a superfood for dogs either. A complete food already covers everything kale offers.
How much is safe?
A teaspoon of finely chopped cooked kale for a small dog, up to a couple of tablespoons for a large one, occasionally rather than daily. If your dog has any kidney or urinary history, leave it out entirely.
How to prepare it
Steam or boil it plain and chop it finely, which makes it far easier to digest than raw leaves and softens the harsh compounds. No oil, no salt, no garlic. Never share kale crisps, which are usually salted and oiled.
Symptoms to watch for
The usual result of too much is wind, gurgling and loose stools. Oxalate-related problems are slow and would show as straining to urinate, blood in the urine, or frequent small wees - all reasons to see a vet rather than adjust the diet yourself.
When to call the vet
If your dog strains to urinate, passes blood, or wees little and often. Check with your vet before feeding kale at all if there is any kidney or stone history.

Common questions
Is kale a superfood for dogs?
No. It is nutritious, but a complete dog food already meets your dog's vitamin and mineral needs, and kale brings oxalates and gut-irritating compounds along with the goodness. Treat it as an occasional low-calorie snack, not a supplement.
Can dogs eat raw kale?
A little will not harm them, but raw kale is tough, hard to digest and more likely to cause wind. Light steaming and fine chopping makes it much easier on the gut.
Why is kale a problem for some dogs?
It is high in oxalates, which matter for dogs with kidney disease or a history of calcium oxalate stones, and it contains isothiocyanates that can irritate the digestive tract in quantity. For a healthy dog having a spoonful occasionally, neither is a practical worry.
