How to Make Watermelon Blueberry Frozen Dog Treats

Making homemade dog treats doesn’t have to be complicated, and this recipe proves it! These Watermelon Blueberry Frozen Dog Treats are made with just three wholesome ingredients and come together in no time.
Not only are they budget-friendly, but they’re also packed with nutrients your dog will benefit from—all while staying cool during warm weather. Here’s a step-by-step guide to help you whip up a batch of these frosty goodies.
Step 1: Gather and Prepare the Ingredients

Before diving into the fun part—blending and freezing—you’ll need to gather your ingredients and prep them properly. This recipe requires just three simple items:
- 2 cups of seedless watermelon – chopped into small cubes
- 1/2 cup of blueberries – fresh or frozen, both work well
- 1/2 cup of plain unsweetened yogurt – Greek yogurt is ideal for a creamy texture
Let’s break it down a bit:
- Watermelon is hydrating, low in calories, and a great source of vitamins A and C. Be sure to use seedless watermelon or remove all black seeds if needed. White seeds are generally soft and safe, but it’s best to minimize them too. The rind should also be removed, as it’s tough for dogs to digest.
- Blueberries are tiny nutritional powerhouses. They’re rich in antioxidants, fiber, and vitamin C. Wash them well before adding them to the recipe. If using frozen blueberries, let them thaw slightly before blending.
- Plain yogurt is packed with probiotics that are great for your dog’s digestion. Always use yogurt with no added sugar or artificial sweeteners. Avoid any yogurt containing xylitol, as it’s toxic to dogs.
Once you’ve measured out your ingredients, it’s time to move on to blending!
Step 2: Blend the Watermelon

Start by adding the cubed watermelon into your blender or food processor. Watermelon has a high water content, so it should blend very easily and create a smooth, juicy puree. This will be the base of your frozen treats and gives them that sweet, refreshing flavor dogs love.
If your blender is having trouble at first, pulse a few times before blending continuously. You don’t need to add water, as watermelon provides plenty of moisture naturally.
Once fully blended, check the consistency—it should be pourable and free of large chunks. If needed, strain the puree to remove any remaining seeds or pulp, though most high-powered blenders can handle them just fine.
Step 3: Add Blueberries and Yogurt

Now that you’ve got your watermelon puree, it’s time to toss in the blueberries and yogurt. Add both to the blender and blend everything together until the mixture is well combined.
You can choose to fully blend the blueberries into the mixture or pulse a few times if you prefer to leave some small chunks for texture. Dogs often enjoy a bit of variety, so either option works!
The yogurt not only adds a creamy element but also helps the treats hold their shape a little better once frozen. It balances the fruitiness and adds a smooth, rich texture that dogs really enjoy.
Give it a quick taste test if you’re curious—while this recipe is for dogs, everything in it is safe and tasty for humans, too!
Step 4: Pour into Molds and Freeze

Once the mixture is ready, it’s time to pour it into your chosen molds. Silicone molds are the easiest to work with—they pop out treats effortlessly once frozen. You can also use ice cube trays or mini muffin pans if that’s what you have on hand.
Use a spoon or a small pitcher to fill each mold cavity. Don’t overfill, as the mixture may expand slightly as it freezes.
Place the filled molds in your freezer and let them chill for at least 3 to 4 hours, or overnight for best results. Make sure the molds are placed on a flat surface in the freezer to avoid spilling.
Step 5: Serve and Store

Once the treats are completely frozen, remove them from the molds and they’re ready to serve! Your dog will love the fruity flavor and icy texture—perfect for hot summer days or as a special snack after a walk.
Serve one or two treats at a time depending on your dog’s size. Always supervise your dog while they enjoy frozen treats, especially if they tend to gulp their food.
To store, place the frozen treats in an airtight container or a freezer-safe zip-top bag. They’ll keep in the freezer for up to two weeks—though they might disappear much faster if your pup has anything to say about it!
These homemade watermelon blueberry frozen dog treats are a simple way to show your furry friend some extra love—with wholesome ingredients you can feel good about.
Common Mistakes & How to Avoid Them
Making homemade dog treats like these 3-ingredient watermelon blueberry frozen bites is simple—but a few small missteps can impact the safety or quality of the final product. To help you get the best results and keep your pup happy and healthy, here are some common mistakes to watch for and how to avoid them.
Using Watermelon with Seeds or Rind
The Mistake: Using seeded watermelon or including parts of the rind in the recipe.
Why It’s a Problem: Watermelon seeds—especially black ones—can cause digestive issues or even intestinal blockages in dogs. The rind is tough and difficult for dogs to digest, potentially leading to stomach upset.
How to Avoid It: Always use seedless watermelon, or take the time to remove all seeds before blending. Also, cut off and discard the rind—only use the soft, red fruit inside.
Using Sweetened or Flavored Yogurt
The Mistake: Grabbing any yogurt from the fridge without checking the label.
Why It’s a Problem: Many flavored yogurts contain added sugars, artificial sweeteners, and xylitol—a sweetener that is toxic to dogs even in small amounts.
How to Avoid It: Always use plain, unsweetened yogurt. Greek yogurt is a great choice because of its creamy texture and added protein. Check labels carefully to ensure there are no harmful additives.
Overfilling the Molds
The Mistake: Pouring the blended mixture to the very top of your mold or ice tray.
Why It’s a Problem: As the mixture freezes, it expands. If molds are overfilled, it can spill over and make a mess in your freezer.
How to Avoid It: Leave a small gap at the top of each mold cavity—about 1/8 to 1/4 inch is enough. This allows for expansion without overflow.
Serving Frozen Treats Without Supervision
The Mistake: Giving your dog a frozen treat and walking away.
Why It’s a Problem: Some dogs tend to gulp food quickly, which can be a choking hazard, especially with hard frozen items.
How to Avoid It: Always supervise your dog when serving frozen treats, especially if they’re a fast eater or a small breed. Consider letting the treat sit for a minute or two to soften slightly before serving.
Making a Batch Too Big to Finish in Time
The Mistake: Doubling or tripling the recipe when you have a small dog or one pup at home.
Why It’s a Problem: These treats are best when eaten within two weeks. Making too many could lead to waste—or worse, feeding expired treats.
How to Avoid It: Stick to one batch unless you have multiple dogs. If you end up with extras, you can always gift them to a fellow dog-loving friend (as long as their pup has no dietary restrictions).
Frequently Asked Questions
Can Dogs Eat Watermelon and Blueberries Safely?
Yes, dogs can safely eat both watermelon and blueberries when prepared properly. Watermelon is hydrating and packed with vitamins A, B6, and C. Just make sure it’s seedless and the rind is removed, as both can cause digestive issues.
Blueberries are rich in antioxidants and fiber, making them a great low-calorie treat. They’re safe for dogs either fresh or frozen and are often used in homemade dog treats for their nutritional value.
Is Yogurt Safe for Dogs in This Recipe?
Yogurt is generally safe for dogs as long as it’s plain, unsweetened, and free of artificial sweeteners like xylitol, which is toxic to dogs. Greek yogurt is often preferred because it’s thicker and contains more protein.
Always check the label before using yogurt to ensure there are no harmful additives. Yogurt can also support healthy digestion thanks to its probiotic content.
Can I Use Frozen Fruit Instead of Fresh?
Absolutely! You can use frozen watermelon chunks and blueberries if fresh produce isn’t available. Just make sure to thaw them slightly before blending to make the mixing process easier. Frozen fruits retain most of their nutrients, and dogs usually enjoy the cold texture in frozen treats.
How Long Should I Freeze the Treats Before Serving?
The treats should be frozen for at least 3 to 4 hours or until they are solid. For best results, leave them in the freezer overnight. Using silicone molds or ice cube trays can help speed up the freezing process and make it easier to remove the treats once they’re fully frozen.
How Should I Store These Dog Treats?
Once the treats are frozen solid, pop them out of the molds and store them in an airtight container or freezer-safe zip-top bag. Keep them in the freezer and use within two weeks for optimal freshness. Make sure the container is sealed tightly to prevent freezer burn or unwanted odors.
How Many Treats Can I Give My Dog at Once?
Portion size depends on your dog’s size, age, and overall diet. For small dogs, one treat at a time is usually enough. Larger dogs can enjoy two or three, depending on the size of the mold used. These treats should be given as occasional snacks and not as meal replacements.
Can I Customize This Recipe With Other Ingredients?
Yes, you can customize it slightly as long as all ingredients are dog-safe. Some pet owners like to add a teaspoon of peanut butter (unsweetened and xylitol-free) or a sprinkle of chia seeds for added nutrients. Avoid adding any chocolate, grapes, or artificial sweeteners, as they are toxic to dogs.
What If My Dog Is Lactose Intolerant?
If your dog is lactose intolerant, you can use a dairy-free alternative such as coconut yogurt or a lactose-free plain yogurt made for dogs. Always introduce new ingredients slowly to see how your dog reacts. Alternatively, you can leave the yogurt out and use just the fruit—it may slightly change the texture but will still be a refreshing treat.
