Can Dogs Eat Kale?

ModerateSmall Amounts

Small amounts of cooked kale are generally fine, but its oxalate content means it shouldn't be fed regularly in large amounts.

Why

Kale contains oxalates, similar to spinach, which in large amounts over time can contribute to bladder or kidney stone formation in predisposed dogs. It also contains compounds that can affect thyroid function if fed in excess. Occasional small amounts aren't a practical concern for most healthy dogs.

How to serve it safely

Cook lightly, serve in small amounts
Avoid regular large feeding, especially for dogs with a history of bladder stones
Not a necessary addition to a dog's diet
