Can Dogs Eat Kale?

Kale is one of those funny vegetables that has a bad rep. Let’s admit that it’s not the tastiest of veggies – it’s widely considered an acquired taste due to its earthy, bitter flavour and tough texture. I, myself, never acquired that taste…

But if you’ve embraced the taste (and amazing health benefits), and it’s a regular in your grocery basket, maybe you’ve pondered, can dogs eat kale? Perhaps, when wilting it in a pan or adding it as a boost to your morning smoothie, you’ve questioned if it’s something to share.

This leafy green is packed with vitamins, minerals, antioxidants, and fibre. In fact, kale is often considered one of the most nutrient-dense vegetables available. So, is it something to share with your canine companion?

The Nutritional Profile of Kale

Kale is often referred to as a “superfood” because it contains an impressive range of nutrients, including:

• Vitamin A
• Vitamin C
• Vitamin K
• B vitamins
• Calcium
• Potassium
• Magnesium
• Iron
• Manganese
• Fibre
• Antioxidants such as lutein and beta-carotene

These nutrients work together to support everything from immune function to healthy aging.

Can dogs eat kale? Kale is as good for your pup as it is for you!

1. Supports Immune Health: Kale contains high levels of vitamins A and C, along with powerful antioxidants that help protect cells from damage caused by free radicals. A healthy antioxidant intake may help support the immune system and overall wellness.
2. Promotes Healthy Digestion: The fibre in kale helps support healthy digestion and regular bowel movements. Fibre also feeds beneficial gut bacteria, which play an important role in digestive and immune health.
3. Supports Eye Health: Kale contains lutein and zeaxanthin, antioxidants that are known for supporting eye health. These nutrients may help protect the eyes from age-related changes and oxidative stress.
4. Helps Maintain Healthy Bones: Vitamin K, calcium, and magnesium all contribute to strong bones and normal body function. While kale shouldn’t be relied upon as a primary source of these nutrients, it can be a healthy addition to a balanced diet.
5. Supports Natural Detoxification: Kale contains compounds called glucosinolates, which help support the body’s natural detoxification pathways. These plant compounds are one reason cruciferous vegetables are often included in healthy diets.
6. May Help Promote Calmness: One of kale’s lesser-known benefits is its magnesium content. Magnesium plays an important role in the nervous system and helps regulate muscle and nerve function. Many dogs today experience stress from busy households, travel, changes in routine, noise, or separation. While kale is not a substitute for proper behavioral support, the magnesium and other nutrients it contains may help support a healthy stress response and overall nervous system function as part of a balanced diet. Additionally, nutrient-rich whole foods help nourish the body, which can contribute to overall well-being and resilience during times of stress.

How to Feed Kale to Dogs

There are several ways to safely offer kale to your dog. It can easily be incorporated into your dog’s regular diet. It pairs well with lean proteins and other vegetables.

Here are the some of our favourite ways to feed it:

1. Raw Kale: Small amounts of finely chopped raw kale can be added to your dog’s meals. Chopping it well makes it easier to digest and may reduce the risk of stomach upset.
2. Lightly Steamed Kale: Steaming is often one of the best ways to prepare kale for dogs. Light steaming softens the leaves, making them easier to digest while preserving many of the nutrients.
3. Pureed Kale: Blending kale into a puree can improve digestibility and allow your dog to absorb more of the nutrients. You can mix a small spoonful into meals.
4. Frozen Kale Treats: Blend kale with dog-safe ingredients such as blueberries, pumpkin, or plain kefir and freeze in silicone molds for a refreshing summer treat.

Serve it plain. It might be tempting to improve the taste, but skip the seasonings.

How much should they eat? Kale should be considered a supplement to your dog’s regular diet rather than a major food source. As a general guideline, slowly work up to:

• Small dogs: 1–2 teaspoons
• Medium dogs: 1–2 tablespoons
• Large dogs: 2–4 tablespoons

Note: some dogs just won’t like it – that’s normal. Not all dogs like all vegetables (sort of like us). So, if your dog turns up their nose at all the different kale offerings, turn to a different veg.

Cautions About Feeding Kale

For most dogs, kale is an amazing addition to the bowl, and there’s nothing you need to worry about.

That said, while kale offers many benefits, there are some important considerations, particularly for dogs with certain existing health concerns.

1. Digestive Upset: Thanks to the high fibre content, introducing too much kale too quickly may cause some digestive upset (gas, bloating, even diarrhea), so start slowly and feed only moderate amounts.
2. Thyroid Concerns: Kale contains naturally occurring compounds called goitrogens. In very large amounts, goitrogens may interfere with normal thyroid function. For healthy dogs eating kale occasionally as part of a varied diet, this is generally not a concern. However, dogs with thyroid disorders should only consume kale after discussing it with their veterinarian.
3. Kidney and Bladder Concerns: Kale contains oxalates, naturally occurring compounds that can contribute to certain types of kidney or bladder stones in susceptible dogs. Dogs with a history of calcium oxalate stones may be better off avoiding kale or eating it only under veterinary guidance.

Other Healthy Greens for Dogs

If your dog enjoys kale, they may also enjoy:

• Spinach
• Romaine lettuce
• Arugula
• Parsley
• Cilantro
• Dandelion greens
• Mustard greens
• Swiss chard

Rotating vegetables can provide a wider variety of nutrients while reducing the chance of overfeeding any one plant compound.

So, can dogs eat kale? Yes, this nutrient-rich leafy green offers a variety of health benefits. From supporting immune function and digestion to providing antioxidants and calming magnesium, kale can be a healthy addition to your dog’s diet when fed appropriately. As part of a balanced diet rich in fresh, whole foods, kale can be a nutritious way to add extra vitamins, minerals, and phytonutrients to your dog’s bowl.
