Safety guide
Is Spinach safe for dogs?
Use with caution
Small amounts of plain spinach are fine, but it is high in oxalates that can affect the kidneys if fed in large or frequent servings.
Spinach is not toxic and a little cooked, plain spinach now and then is generally safe for a healthy dog. The concern is its high oxalic-acid content, which can bind calcium and, in large or frequent amounts, place strain on the kidneys — so feed only sparingly. Serve it steamed or boiled and plain, with no onion, garlic, salt or butter, and avoid it altogether in dogs with kidney disease.
