Frozen Watermelon Blueberry Cubes for Dogs

There’s something especially satisfying about making dog treats that are as beautiful as they are healthy and these Watermelon & Blueberry Swirl Bites deliver both. With their vibrant pink base and deep purple swirls, they look like a summer dessert straight out of a boutique freezer, yet they’re made with just a few simple, dog-safe ingredients.

This recipe came to life on a hot afternoon while my dog, Benji, lounged beside me, tongue out, watching me snack on cold watermelon. That hopeful stare sparked an idea: capture the refreshing sweetness of watermelon and the antioxidant boost of blueberries in a frozen treat made just for him. One batch later, these swirl bites became a summer staple.


Watermelon is incredibly hydrating, low in calories, and packed with vitamins A, B6, and C making it ideal for warm weather treats. Blueberries may be small, but they’re loaded with antioxidants, fiber, and nutrients that support overall health. Together, they create a refreshing, functional snack that cools and nourishes at the same time.

If you’re mindful about what goes into your dog’s treats, this recipe checks all the boxes: fresh, minimal ingredients with real benefits.


  • 2 cups seedless watermelon, chopped
  • ½ cup blueberries, fresh or frozen
  • 1 tablespoon plain Greek yogurt (optional, unsweetened & unflavored)
  • Silicone molds or ice cube trays

Optional add-ins:

  • A few fresh mint leaves
  • 1 teaspoon chia seeds
  • A few drops of salmon oil

  1. Blend the watermelon
    Puree the watermelon until smooth. If it’s very watery, you can strain slightly but extra hydration is never a bad thing.
  2. Prepare the blueberry swirl
    Blend the blueberries just until broken down. For a creamier swirl, blend them with the Greek yogurt.
  3. Create the swirl
    Fill molds about ¾ full with watermelon puree. Add a spoonful of blueberry mixture, then gently swirl with a toothpick or knife.
  4. Freeze
    Freeze for at least 4 hours or overnight until fully set.
  5. Serve
    Pop out and serve straight from the freezer on a warm day.

  • Store in an airtight container or freezer bag
  • Keeps well for up to 2 weeks
  • Serve one at a time, especially for smaller dogs

These treats are perfect after walks, on hot afternoons, or as a gentle enrichment snack.


  • Skip yogurt for dairy-sensitive dogs
  • Use mini molds for small breeds
  • Reduce fruit and add cucumber or zucchini for lower sugar
  • Mix in pumpkin purée for added fiber

The swirl method makes this recipe endlessly adaptable.


These Watermelon & Blueberry Swirl Bites aren’t just frozen treats they’re moments. The quiet anticipation by the freezer, the first crunch, the tail wag that follows. Making treats at home is a small act of love that turns into a shared ritual, and that’s what makes it special.

If you’re looking for a simple, refreshing way to spoil your dog this summer, this recipe is a perfect place to start bright, wholesome, and made with care in every swirl. 🍉🫐🐾
