Dogs can have collard greens, but only in small, carefully prepared amounts and not all dogs should eat them.

Are collard greens safe?

• Plain, cooked collard green leaves (no stems, seasonings, or oil) are generally considered safe for healthy dogs in moderation.

• Dogs with kidney or bladder issues should avoid collard greens because they are high in compounds (like calcium oxalate and isothiocyanates) that can contribute to stones or irritation.

Benefits for dogs

• Collard greens provide vitamins A, C, and K, folate, and minerals like calcium and magnesium that can support immune function, bone health, and overall wellness.

• They are high in fiber, which can help digestion, but too much fiber can cause gas, diarrhea, or stomach upset.

How to prepare and how much

• Only feed cooked, soft leaves: steam or lightly sauté in water, then cool; do not add salt, butter, garlic, onions, or other seasonings, and remove the tough stems.

• Start with a very small portion, such as a tablespoon or two mixed into regular food for a medium dog, and watch for vomiting, diarrhea, or itchiness; many sources suggest staying under about half a cup per day and adjusting down for small dogs.

When to avoid them

• Avoid raw collard greens, canned collards (because of salt and preservatives), and any collards cooked with ham, bacon, fat, or spicy ingredients, as these can upset your dog’s stomach or be harmful.

• Skip collard greens and talk to a vet first if your dog has a history of kidney/bladder stones, chronic digestive issues, or food allergies.
