When watermelon season rolls around, it’s easy to find at just about any grocery store. And since Luna loves watermelon, it’s a great time to make some of her favorite watermelon treats.
These cucumber watermelon mint frozen dog treats combine watermelon and cucumber with plain Greek yogurt and a little fresh mint. They only take a few minutes to put together before going into the freezer.
I like recipes like this because they’re simple and use ingredients that are easy to find. Plus, Luna is always happy to volunteer for taste-testing duty.
If your dog enjoys watermelon and cucumber, these are an easy frozen treat to make while watermelon is in season.

Why I Like This Recipe
This is one of those dog treat recipes that doesn’t take much effort. Add everything to the blender, pour the mixture into molds, and let the freezer do the rest.
It also uses just four ingredients, and there’s very little prep involved. I can make a batch, keep the treats in the freezer, and have them ready whenever I want to give Luna something a little different.
And, of course, anything with watermelon tends to get Luna’s approval.
Ingredients
- ½ c English cucumber
- 1 c watermelon
- ½ c plain unsweetened Greek yogurt
- 3 fresh mint leaves (do not use pennyroyal mint)
Ingredient Notes
Watermelon
Watermelon is mostly water and can be given to dogs in moderation. Remove the rind and seeds before using it in homemade dog treats.
Cucumber
Cucumber is another dog-friendly ingredient that contains a lot of water. I use English cucumber because it has thin skin and very few seeds, which also means less prep work.
Plain Greek Yogurt
Use plain, unsweetened Greek yogurt for these treats. Check the ingredient list before using yogurt for your dog, and avoid products containing xylitol.
Some dogs don’t tolerate dairy well, so keep that in mind if Greek yogurt is new to your dog.
Fresh Mint
A small amount of common culinary mint can be used in dog treats. I only use three fresh mint leaves for this entire recipe.
Do not use pennyroyal mint. Pennyroyal is unsafe for dogs.
If you aren’t sure which type of mint you have, leave it out. The treats will still work without it.
Directions
Wash and chop the cucumber and watermelon, removing the rind and seeds from the watermelon.
Add the cucumber, watermelon, mint leaves, and Greek yogurt to a blender or food processor.
Blend until you get a smooth puree.
Pour or spoon into silicone molds. These paw and bone-shaped molds work well.
Place in the freezer for at least 4 hours or until frozen.
Once frozen, remove from the molds.
Give one to your dog. This is Luna’s favorite step!
Place the rest in an airtight container, like a freezer bag, and store in the freezer for up to 4 months.
Tips
Place the silicone molds on a cookie sheet before filling to make transferring to the freezer easier.
If you don’t have silicone molds, you can use ice cube trays as well.
Always consult your vet before giving your dog any new foods, especially if your dog has any known health conditions or allergies.
Frequently Asked Questions
Can I make these without mint?
Yes. You can leave the mint out if you don’t have any or don’t want to use it. It won’t affect the basic recipe.
Can I use a regular cucumber instead of an English cucumber?
Yes. If you use a regular cucumber, you may want to peel it and remove any large seeds before adding it to the blender.
Can I make these without Greek yogurt?
I haven’t tested this recipe without Greek yogurt, so I can’t say how a substitution will affect the finished treats.
If your dog can’t have dairy, you may want to try one of my other frozen dog treat recipes instead.
How long do homemade frozen dog treats last?
I store these treats in an airtight freezer-safe container or freezer bag for up to 4 months.
Once they’re frozen solid, I remove them from the silicone molds before storing them.
How many frozen treats can I give my dog?
That depends on the size of your treats, your dog, and what else your dog eats during the day.
Treats should generally make up no more than 10% of your dog’s daily calories. If you’re unsure how these treats fit into your dog’s diet, ask your veterinarian.

Final Thoughts
These cucumber watermelon mint frozen dog treats are an easy way to make something a little different for your dog without spending a lot of time in the kitchen.
I especially like frozen treats because I can make a batch ahead of time and keep them in the freezer for Luna. When watermelon is easy to find, this gives me another simple recipe to make with it.
Of course, every dog is different. Your dog may love cucumber, watermelon, and mint as much as Luna does, or decide that cucumber has personally offended them.
Start with a small amount if these ingredients are new to your dog, and talk to your veterinarian if you have questions about whether any of the ingredients are appropriate for your dog.
And as always, treats are treats, even when they’re homemade. Keep portions reasonable and do what works for your dog.
