Let’s talk about something that sounds a little weird at first but ends up making a whole lot of sense—green smoothies… for your dog.
I know, it’s not the first thing you’d think to make for your pup, but hear me out. If you’re already someone who drinks green smoothies, loves boosting your own immune system, and maybe has even spent one too many hours Googling “natural ways to keep my dog healthy,” then this recipe is 100% for you.
This immunity green smoothie is packed with all the good stuff your dog needs: vitamins, antioxidants, gut-friendly bacteria, and a few ingredients they’ll actually love. And before you worry—yes, every ingredient has been fact-checked to be safe for dogs (in the right quantities). No mystery powders. No “iffy” ingredients. Just whole, real food that supports your pup’s health from the inside out.
Whether your dog’s been feeling a little blah lately, you’re trying to support them during allergy season, or you’re just that kind of person who likes knowing they’re giving their dog the best, this smoothie will help.
So let’s jump in. And don’t worry—it’s really easy. Like, blender-easy.
What You’ll Need
Here’s everything you’ll need to make this smoothie. Nothing fancy. Nothing complicated. Just good, wholesome stuff:
- ½ cup fresh spinach Full of vitamins A, C, and K, as well as iron and fiber. It’s great for boosting the immune system and supporting healthy digestion.
- ½ banana Gives the smoothie natural sweetness (don’t worry, it’s not overpowering), plus potassium and magnesium. It also makes everything a bit creamier.
- 1 small apple (peeled and cored) A source of vitamin C, antioxidants, and fiber. But make sure to remove the seeds and core—those parts aren’t dog-friendly.
- ½ cup plain kefir or unsweetened plain yogurt This is where the probiotics come in. Helps support your dog’s gut health, which is directly connected to their immune system.
- ¼ cup unsweetened coconut water Hydrating, full of electrolytes, and a little tropical flair. Just be sure it doesn’t contain added sugars or artificial ingredients.
- ¼ teaspoon spirulina powder (optional) Spirulina is a nutrient-dense algae that’s rich in protein and antioxidants. A tiny bit goes a long way.
- 1 teaspoon ground flaxseed High in omega-3 fatty acids, which support a shiny coat and healthy skin. Also helps with inflammation.
- Optional: 1 small cooked liver cube or 3 small freeze-dried liver treats If your dog’s a picky eater, this adds a flavor boost they usually can’t resist. Think of it like smoothie “bacon bits.”
Pro Tips
Making a smoothie for your dog isn’t rocket science, but these tips will help make sure things go smoothly (pun intended):
- Start Small If this is your dog’s first time trying any of these ingredients, start with a small serving. Just to be safe and make sure everything agrees with their tummy.
- Use Organic When You Can Especially for the spinach and apples. Dogs are more sensitive to certain pesticides, so it’s always better to go organic if it’s available.
- Double Check the Coconut Water Read the label. You don’t want any added sugar, artificial sweeteners, or preservatives. Pure coconut water only.
- Freeze Leftovers in Ice Trays This is one of my favorite hacks. Make a batch, pour the extras into an ice cube tray, and freeze them. That way, you’ve got single-serve smoothie cubes for later.
- Blend It Smooth Some dogs will turn their nose up if there are chunks floating around. Make sure you blend until silky smooth—especially if your pup is a texture snob.
Tools You’ll Need
No need to bust out your entire kitchen drawer. This recipe only needs a few basics:
- Blender or food processor
- Measuring cups and spoons
- Knife and cutting board
- Ice cube tray or silicone molds (if you plan to freeze extras)
Substitutions and Variations
Here’s where you can switch things up based on what you have on hand or your dog’s preferences:
- Spinach Can be swapped for kale, parsley, or even dandelion greens (yes, those are safe for dogs in moderation).
- Banana Don’t have one on hand? Try a few frozen blueberries or a small spoonful of pumpkin puree.
- Yogurt/Kefir If your dog is sensitive to dairy, go with goat’s milk or a dairy-free coconut-based yogurt that doesn’t have added sugar.
- Coconut Water Not a fan? Use plain filtered water or low-sodium bone broth.
- Flaxseed Chia seeds work in a pinch and also give that omega-3 boost.
- Liver Treats Totally optional. This just adds flavor and makes the smoothie more tempting for picky pups.
Make Ahead Tips
One of the best things about this smoothie is that it’s freezer-friendly. Here’s how to stay ahead of the game:
- Make a full batch and pour it into silicone molds or an ice cube tray.
- Freeze solid, then pop out and store in a freezer-safe container or bag.
- Just thaw a few cubes in the fridge the night before or microwave on low for a few seconds (but test the temp before serving).
Pro move: Toss a frozen cube into their bowl on a hot day for a cool treat.
How to Make It
Alright, let’s get down to the step-by-step. This takes about 5 minutes, tops.
- Wash and prep your ingredients. Peel and core the apple. Peel the banana. Rinse the spinach.
- Add everything to the blender: spinach, banana, apple, yogurt or kefir, coconut water, flaxseed, spirulina, and the liver treat if using.
- Blend on high until smooth. If it’s too thick, add a splash of water or extra coconut water to thin it out.
- Serve immediately in a dog bowl, over kibble, or frozen into treats.
- Store leftovers in the fridge (up to 2 days) or freezer (up to 1 month).

FAQ
Can dogs have spinach regularly? Yes, in moderation. Spinach is safe for most dogs when given occasionally, but not daily in large amounts due to its oxalate content.
Is spirulina really safe for dogs? It is when given in small doses (like ¼ teaspoon or less depending on the dog’s size). Always use food-grade spirulina, not something from an unknown source.
Can I use cow’s milk instead of kefir or yogurt? Not the best choice. Many dogs are lactose intolerant, and regular milk can cause tummy issues. Stick to kefir, goat’s milk, or a non-dairy, dog-safe yogurt.
How often should I give this to my dog? 2 to 3 times a week is perfect for most dogs. It’s meant to support, not replace, a balanced diet.
What if my dog won’t drink it? Try mixing it with their food, adding a stronger-smelling topper like liver, or freezing into a cube for a less “weird” delivery.
