🥬 Vegetable

Can dogs eat spinach?

In moderation
Only in small, infrequent amounts, because spinach is very high in oxalic acid.

Why

Spinach contains vitamins A, B, C, and K plus iron and antioxidants, but it is very high in oxalic acid, which can interfere with calcium absorption and, in large quantities, burden the kidneys. A dog would have to eat a lot to cause harm, but spinach is not among the best vegetables to share. Serve it steamed and plain, with no salt, oil, onion, or garlic.

How much is safe

If your dog's kidneys are healthy, offer only small amounts of steamed, plain spinach infrequently.

Warning signs to watch for

Large amounts may cause gastrointestinal upset and, over time, could stress the kidneys; consult your vet before feeding.
