Why Make Cucumber Water for Your Dog
There are so many good reasons to make this simple drink for your pup. Here are the top ones that will have tails wagging!
As a dog parent, it feels great knowing you can whip up a simple, nutritious treat your pup will love.
When you make cucumber water at home, you’re in charge of what goes in it. No worrying about hidden ingredients in store-bought versions like artificial flavors, lemon or lime juice, or even xylitol, which is unsafe for dogs.
It’s also a fun way to change things up. Instead of plain water, your pup gets a tasty little twist that still helps keep them hydrated.
And if it’s hot outside or your dog has been super active, cucumber water is extra helpful. Cucumbers naturally contain electrolytes, which can replenish what your dog loses during playtime while cooling them off at the same time.
Ingredients
You only need two simple ingredients to make this recipe. See the recipe variations section below for optional add-ins.
- Cucumber
- Water

How to Make Cucumber Water for Dogs
Making cucumber water is super simple! Here’s how:
- Fill a 1-quart glass jar about halfway with water.
- Wash the cucumber to remove any dirt or pesticide residue on the skin.
- Use a sharp knife to cut the cucumber into thin slices.
- Place the raw cucumber slices in the jar.
- Add enough water to make 4 cups (1 quart).
- Cover the jar and refrigerate it for 2 to 4 hours to allow the cucumber to infuse into the water.

- Stir well and strain the water.
- Pour the cucumber water into a bowl for your dog to enjoy.
Give the cucumber slices to your dog as a separate snack. Placing pieces in the bowl with the water could cause a choking hazard.

To peel or not to peel the cucumber?
Cucumber skin is safe for dogs to eat. It’s full of fiber, and it’s where vitamins are more concentrated. It’s up to you if you want to remove the skin.
Remove cucumber seeds or not?
Cucumber seeds are safe for dogs to eat. However, some dogs and puppies have trouble digesting the seeds and could get an upset stomach. If that is the case for your dog, then remove the seeds. Cut the cucumber in half lengthwise and scrape out the seeds with a spoon.
Recipe Variations
One of the best things about cucumber water is how easy it is to change up the flavors for your pup. Try mixing in a few dog-safe add-ins your furry friend might enjoy:
- Berries – a handful of blackberries, blueberries, raspberries, or strawberries adds a fruity twist.
- Fresh fruit – Apple, cantaloupe, peach, pear, pineapple, mango, and watermelon are all great options. Just be sure to remove any core, seeds, pits, or rinds first.
- Fresh mint leaves – About 6 leaves will give the water a cool, refreshing touch.
No matter which variation you try, always strain out the fruit before serving and offer it separately as a tasty little bonus treat. Discard the mint leaves.
How much cucumber water can dogs have?
It’s natural to wonder how much of this tasty drink is safe for your pup, so here’s a simple guide to help you serve the right amount.
Treat cucumber water just like plain water. You can fill your dog’s bowl with it.
As for the cucumber slices, it really depends on your dog’s size. A good guideline is about 1-2 slices for every 10 pounds of body weight. Smaller pups will need less, while bigger dogs can handle a bit more. Just keep in mind that too much cucumber can upset their stomach. Because cucumbers are high in water and fiber, eating a large amount could lead to bloating, gas, loose stools, or even diarrhea.
Whenever you introduce something new into your dog’s diet, start small and see how they react. And of course, if your pup shows any signs of discomfort, stop serving it and check in with your vet right away.
How to Store Cucumber Water and How Long it Lasts
Cucumber water is best when it’s fresh, but you can definitely store it to have on hand. Strain the water into a glass jar or pitcher and keep it in the fridge for up to 3 days.
The cucumber slices can also be saved. Just pop them into an airtight container or zip-top bag and refrigerate for up to 3 days.
Want to keep it longer? Freeze it! Pour the cucumber water into an ice cube tray, freeze until solid, then transfer the cubes to a freezer bag or container. You can give the cubes straight to your dog as a frosty treat or thaw them in the fridge overnight.
Cucumber slices also freeze well. Lay them out on a baking sheet lined with parchment or a silicone mat, freeze, then store them in a freezer-safe container or bag. They’ll last for up to 3 months and make great little frozen snacks for your pup.
Can people drink this cucumber water?
Yep, they sure can! In fact, it’s just as tasty for humans as it is for dogs. Many people know it as “spa water” because of its light, refreshing flavor. Go ahead and pour yourself a glass. You and your pup can enjoy it together.
