Benefits of Broccoli For Dogs

Nutrition

Jul 1

We love it when pet parents start adding fresh veggies to their dog’s bowl, and broccoli is one of my top recommendations. It’s easy to find, dogs often enjoy the taste, and it’s packed with nutrients that can support your dog’s overall wellness.

And yes… even if your dog eats kibble, tossing a few florets into the bowl (or better yet, some chopped stems!) is a great upgrade.

Let’s talk about how broccoli fits into a fresh food plan, when it’s best raw vs. cooked, and why its nutrients may help support everything from gut health to calm behavior.

Why Broccoli is a Great Veggie for Dogs

Broccoli is a cruciferous vegetable rich in:

Potassium
Vitamin A and C
Vitamin K
Folate
Antioxidant compounds
Dietary fiber

When fed appropriately, these nutrients can help support:

Healthy digestion and regular elimination
A robust immune system
Natural detoxification pathways
Cellular and tissue health
Balanced behavior and mood (yes, nutrition influences behavior too!)

Broccoli also contains sulforaphane, a well-researched plant compound found in cruciferous vegetables that supports the body's natural detox processes, antioxidant defenses, and healthy inflammation response.

Raw vs. Cooked Broccoli for Dogs

You’ve likely heard that veggies should be lightly steamed or sautéed for dogs. That’s still true for many pups — it can improve digestibility and reduce compounds that may be irritating in large amounts.

However, some holistic veterinarians and canine nutritionists now encourage feeding raw broccoli occasionally because it may retain more of its beneficial compounds when uncooked — especially sulforaphane.

Here’s how to get the best of both worlds:

Raw broccoli: Chop finely and let it sit for 30–40 minutes before feeding. This gives enzymes time to activate sulforaphane.
Lightly cooked broccoli: Steam, blanch, or sauté with a bit of healthy oil to support absorption and make it easier to digest.

Try both and see how your dog does! If your dog has a sensitive tummy, start with cooked and work your way toward raw if appropriate.

What About Broccoli and the Thyroid?

Cruciferous vegetables like broccoli have been questioned for their potential impact on thyroid function. It’s true that large quantities of raw broccoli might not be ideal for dogs with known thyroid issues. However, cooking significantly reduces this concern, and moderate feeding is perfectly reasonable for most dogs.

If your dog has been diagnosed with thyroid imbalance, always consult with your vet or work with a canine wellness coach to personalize their nutrition strategy.

Quick Tip: Frozen Broccoli and Sulforaphane

Frozen broccoli is convenient, but the blanching process used before freezing can deactivate the enzyme needed to produce sulforaphane. You can still use it — but for a sulforaphane boost, try adding:

A pinch of grated Daikon radish
Chopped radish sprouts

These ingredients contain the same enzyme (myrosinase) that helps unlock the broccoli’s full potential.

How Much Broccoli Should I Feed?

Vegetables should make up no more than 20% of the total meal volume for most dogs. But even a small amount of broccoli — a few pieces from your cutting board or leftovers from dinner — can be a meaningful upgrade.

Rotate your veggies to include:

Kale
Cauliflower
Collard greens
Broccoli rabe
Cabbage (cooked, not raw)

Avoid feeding the same ingredient every day to keep your dog’s diet balanced and varied.

Dana’s Thoughts

I always say… don’t overlook the power of food. Broccoli is one of those simple, affordable veggies that can do a lot of good when used wisely. When we support the gut, detox pathways, and nutrient intake, we often see improvements in energy, skin, digestion, and even behavior.

That’s why we build these veggies into our wellness plans.
