Yes, dogs can eat kale in moderation, and this leafy green can offer some nutritional benefits. However, before adding kale to your pup’s diet, there are a few important factors to consider. While plain, steamed, or finely chopped kale is generally safe in small amounts, certain preparations—like seasoned, creamed, or heavily sautéed kale—can contain ingredients that may harm dogs. Plus, what about kale stems? Is raw kale better than cooked? Can too much kale cause digestive upset or other health concerns? This guide will explore the benefits, potential risks, and the safest way to incorporate kale into your dog’s diet.

Is Kale Good For Dogs?

Kale can be a nutritious addition to a dog’s diet when given in moderation.

  • Kale is low in calories and contains virtually no cholesterol, making it a heart-friendly vegetable option for dogs when served plain.
  • It is rich in vitamins A, C, and K, which support immune health, vision, skin integrity, and proper blood clotting.
  • Provides calcium, potassium, magnesium, and iron, contributing to strong bones, muscle function, and healthy circulation.
  • Contains antioxidants such as beta-carotene and flavonoids, which help combat oxidative stress and support cellular health.
  • Kale is a good source of fiber, promoting healthy digestion and supporting beneficial gut bacteria when fed in small amounts.
  • Contains plant-based phytonutrients that may support detoxification processes in the body.

Always serve kale plain, steamed, or finely chopped to improve digestibility. Avoid seasoning, oils, garlic, or onion, as these can be harmful to dogs. Because kale contains compounds like oxalates and isothiocyanates, it should only be offered in moderation—especially for dogs prone to kidney or bladder issues.

Risks & Considerations Before Feeding Kale to Dogs

While kale can be a safe and nutritious vegetable for dogs when given in moderation, there are several risks and considerations to keep in mind before adding it to your dog’s bowl:

  • Avoid large stems: Kale stems can be tough and fibrous, making them harder to digest and potentially posing a choking hazard—especially for small dogs. Remove thick stems and chop leaves into bite-sized pieces.
  • Raw kale in excess is not ideal: Feeding large amounts of raw kale may be harder on your dog’s digestive system. Lightly steaming kale can improve digestibility and reduce the risk of stomach upset.
  • Contains oxalates: Kale naturally contains oxalates, which can contribute to kidney or bladder stone formation in dogs prone to urinary issues. Dogs with a history of kidney problems should avoid frequent consumption.
  • Isothiocyanates and digestive upset: Kale contains compounds called isothiocyanates that, in large amounts, may cause mild to moderate gastrointestinal irritation, including gas, bloating, or diarrhea.
  • Thyroid considerations: As a cruciferous vegetable, kale may interfere with thyroid function if fed excessively over time, particularly in dogs with existing thyroid conditions.

Are Dogs Allergic to Kale?

Most dogs are not allergic to kale, and it’s generally considered safe for canine consumption. However, some dogs may develop an allergic reaction, as with any food. Food allergies in dogs typically manifest as itchy skin, hives, infections, and anaphylaxis (a medical emergency) in severe cases. If you suspect your dog is having an allergic reaction to any food, including kale, it is crucial to consult a veterinarian.

Additionally, conducting an at-home dog allergy test like the 5Strands can help determine if your dog is allergic or intolerant to certain foods. For a more comprehensive approach, consider an at-home dog gut health test, like the Embark Gut Health Test, which can provide deeper insights into your dog’s digestive health and immune function. These tests can identify food sensitivities, bacterial imbalances, and other underlying issues contributing to allergies, helping you take proactive steps to prevent discomfort and support your dog’s overall well-being.

Risks

The following symptoms may indicate a bad reaction to kale.

  • Discomfort and bloating
  • Excess gas
  • Upset stomach
  • Diarrhea
  • Vomiting
  • Decreased appetite
  • Lethargy

What to Do If A Dog Reacts Badly to Kales

Dogs showing worsening symptoms, such as blood in their vomit or stool, difficulty breathing, weakness, or collapse, should be taken to the veterinarian immediately.

1. Contact a veterinarian immediately: Even if your dog seems fine, contact your veterinarian or an emergency pet poison hotline right away. This includes services such as the ASPCA Animal Poison Control Center at 1-888-426-4435 or the Pet Poison Helpline at 1-855-764-7661. If you can’t reach your vet, you can chat live with a registered online veterinary professional via our online vet chat or video chat support (24 hours a day, 7 days a week).

2. Gather important information: When speaking to a vet, provide: Quantity consumed (estimate if unsure), time of ingestion, and dog’s weight and breed (to assess potential risk).

3. Follow veterinary instructions: The vet may suggest monitoring at home or emergency treatment at the clinic.

  • Keep your dog calm and prevent them from eating anything else.
  • Be prepared to transport your dog to the vet quickly if advised.
  • Bring any remaining kale or packaging to help the vet assess the situation.

How to Safely Feed Kale to Dogs

When feeding kale to your dog, it’s important to follow a few simple guidelines to keep them safe:

  • Remove thick stems and tough ribs
  • Serve in moderation
  • Start with small amounts
  • Avoid seasoned, creamed, or heavily sautéed kale
  • Lightly steam and chop into small pieces
  • Monitor for any reactions

Ways to Feed Kale to Dogs

  • As a topper: Finely chopped or lightly steamed kale can be sprinkled over your dog’s regular food for an added nutrient boost.
  • Mixed into meals: Blend small amounts of cooked kale into homemade dog food recipes for extra vitamins and minerals.
  • Kale purée: Steam and purée kale, then mix a spoonful into your dog’s meal to improve digestibility.
  • Combined with other veggies: Mix kale with dog-safe vegetables like carrots or green beans for a balanced, fiber-rich side.
  • Frozen veggie blend: Blend kale with water and freeze in silicone molds for a small, refreshing treat in warm weather.
  • Dehydrated kale chips (plain only): If making at home, ensure they are completely plain—no salt, oil, garlic, or seasoning—and offer sparingly.

As with any new food, start slowly and feed gradually to give your dog’s digestive system time to adjust. Moderation is key to safely incorporating kale into your dog’s diet.

How Much Kale Can Dogs Eat?

Treats should only constitute 10% of your dog’s diet, with the remaining 90% coming from well-balanced dog food. This guideline also applies to healthy treats like kale. Below, you’ll find general guidelines for safely portioning kale based on your dog’s weight.

Dog Size Serving Size (From 100g of Kale) Breed Examples
Extra-small (2–15 lbs.) 1–2 teaspoons finely chopped (5–10g) Shih Tzu, Yorkies, Chihuahuas, Maltese
Small (16–25 lbs.) 1 tablespoon finely chopped (10–15g) Boston Terriers, Beagles, Dachshunds
Medium (26–60 lbs.) 2 tablespoons finely chopped (20–30g) Bulldogs, Basset Hounds, Border Collies
Large (61–90 lbs.) 3–4 tablespoons finely chopped (30–40g) Golden Retrievers, Pit Bulls, Boxers, Labrador Retrievers
Extra-large (91+ lbs.) ¼–½ cup finely chopped (40–50g) Bullmastiffs, Great Danes, Saint Bernards, Great Pyrenees

Can Puppies Eat Kale?

Yes, puppies can eat kale, but only in moderation and in very small amounts. Since puppies have more sensitive digestive systems, it’s best to start with just a tiny portion—such as a teaspoon of lightly steamed, finely chopped kale—to see how they react. Feeding too much kale at once can lead to digestive upset, as puppies’ stomachs are still developing and may struggle with its fiber content and natural compounds. Additionally, plain, cooked kale is the safest option—avoid raw, seasoned, sautéed, or creamed kale, as added oils, salt, garlic, or onions can be harmful to puppies. When introducing kale or any new food, avoid giving multiple new foods on the same day so you can properly monitor for sensitivities or allergies. If your puppy experiences diarrhea, vomiting, or excessive gas, offering only one new food at a time makes it easier to identify the cause. Try offering a teaspoon of steamed, unseasoned, finely diced kale, then wait a few days to observe how your puppy’s digestive system responds before offering more. Always remove thick stems and chop the leaves thoroughly to reduce the risk of choking and improve digestibility.

Alternatives

Here’s a list of alternatives to kale that are just as safe and nutritious.

Frequently Asked Questions

Kale stems are not toxic, but they can be tough and fibrous, making them harder for dogs to digest. Thick stems may also pose a choking hazard, especially for small breeds. If you plan to feed kale, it’s best to remove the large stems and only offer finely chopped leaves. This helps reduce digestive discomfort and makes the vegetable safer overall.

Cooked kale is the safest way to serve it to dogs. Lightly steaming the leaves softens the fiber, improves digestibility, and reduces the risk of stomach upset. Always serve it plain—without oil, salt, garlic, onions, or seasoning. Moderation is key, as too much can still cause digestive issues.

Yes, dogs can eat kale greens in small amounts. The leafy part contains vitamins A, C, and K, along with fiber and antioxidants that may support overall health. However, kale also contains oxalates and natural compounds that can irritate the digestive tract if fed in excess. Offer small portions occasionally rather than daily.

Kale stalks are similar to stems and can be quite tough for dogs to chew and digest. Large pieces may create a choking risk or cause stomach discomfort. If feeding kale, remove thick stalks and chop the leaves into bite-sized pieces. Smaller, softer portions are much safer.

Dogs can eat raw kale, but it may be harder to digest than cooked kale. Raw leaves are more fibrous and may lead to gas or mild stomach upset in sensitive dogs. Light steaming is generally recommended to improve digestibility. Always introduce it slowly and monitor for any adverse reactions.

Plain, homemade kale chips without salt, oil, or seasoning can be offered in very small amounts. However, most store-bought kale chips contain added salt or flavorings that are not safe for dogs. Even plain chips should be given sparingly due to kale’s oxalate content. Fresh, lightly steamed kale is a better option.

Puppies can eat kale in very small amounts, but their digestive systems are more sensitive. Start with a teaspoon of lightly steamed, finely chopped kale and monitor for any signs of upset. Avoid raw or seasoned preparations. Because puppies are still developing, kale should only be an occasional addition—not a regular part of their diet.

The Bottom Line

Kale can be a nutrient-rich addition to your dog’s diet when served properly and in moderation. Packed with vitamins A, C, and K, along with fiber and antioxidants, it offers potential health benefits—but it’s not without limitations. Because kale contains oxalates and natural compounds that may irritate the digestive system in large amounts, portion control is essential, especially for dogs prone to kidney, bladder, or thyroid issues. The safest approach is to serve it plain, lightly steamed, and finely chopped, treating it as an occasional supplement rather than a daily staple. When introduced thoughtfully and fed responsibly, kale can be a healthy boost—not a dietary risk—to your dog’s bowl.

Whether you’re introducing kale or any new treat, unexpected reactions can happen. Having the right pet insurance ensures you can handle any vet visits with peace of mind.
