Benefits of Cucumbers for Dogs

Before I show you how to properly prepare and feed your doggo some cucumbers, let’s talk about the health benefits this veggie brings to the table.


Cucumbers are like little hydration heroes for your dog. They’re about 95% water, perfect for keeping your pup’s body well-hydrated, especially on those scorching summer days.

Proper hydration will support their overall health, maintain their energy levels, and prevent dehydration, sometimes leading to heatstroke.

Low In Calories

Cucumbers are incredibly low in calories, meaning your pup can munch on them guilt-free. If your dog needs to lose a few pounds or maintain its current weight, cucumbers are a smart choice to provide healthy nutrients without overeating.

Rich In Vitamins

They contain vitamins B, C, and K, all of which play important roles in your dog’s well-being. For example, vitamin B vitamins contribute to a healthy metabolism. Vitamin C boosts the immune system, and vitamin K helps with blood clotting.

Aid In Digestion

Cucumbers also contain a solid amount of dietary fiber, which is important for your dog’s digestion – it helps maintain regular bowel movements and can prevent constipation.

Good Source of Minerals 

These green gems provide potassium, phosphorus, magnesium, iron, and calcium minerals

Potassium is excellent for muscle function and heart health. 

Phosphorus and magnesium are vital for bone health and maintaining a strong metabolism. Iron supports healthy blood, and calcium is essential for strong bones.

Fresh Breath

Here’s a fun one: in addition to brushing,  cucumbers can help with your dog’s breath! Chewing on cucumber slices can naturally freshen their breath, thanks to cucumbers’ mild, natural scent.

How to Safely Share Cucumbers with Your Pup

Now that we’ve established that cucumbers are one of the healthiest veggies for dogs, let’s talk about the dos and don’ts of serving this green snack to your pup:


  • Wash thoroughly: Just like any other vegetable, wash cucumbers thoroughly before sharing them with your dog to remove any pesticides or dirt.
  • Cut into bite-sized pieces: Dogs can often rush when they eat and simply try to gulp down the food, especially when hungry. So try to chop the cucumber into small, bite-sized, manageable pieces to prevent choking hazards.
  • Remove seeds: While cucumber seeds are generally safe for dogs, they can be tough on your pup’s digestive system and cause GI upset. 
  • Start slow: Since some dogs may be allergic to cucumbers, introduce them in moderation and small amounts to your furry friend.
  • Cut off the ends: a chemical compound called cucurbitacin can be in the roots, stems, and leaves. It can also be present in cucumber fruit, contributing to a bitter taste. In small amounts, this compound is unlikely to harm your dog, but for added safety, consider removing the ends and peeling off the cucumber.
  • Serve plain: Considering our four-legged friends have digestive systems that work differently and can’t process the food the same way we do, avoid adding salt, spices, or seasonings to the cucumber – keep it plain and simple.


  • Avoid overfeeding: Like any treat, moderation is key. Too much of a good thing can upset your dog’s stomach or lead to diarrhea.
  • Avoid bitter cucumbers: Some varieties can be bitter and may not sit well with your dog’s taste buds. Stick to the mild, regular cucumbers.
  • Avoid pickles: While pickles have a similar nutritional content as cucumbers, they often contain a lot of salt, preservatives, and other additives. Since dogs can’t process these ingredients well, it’s best to avoid feeding pickles to your doggo.

How Much Cucumber Can Dogs Eat?

The amount of cucumber depends on your dog’s size. While about two slices are enough for small dogs, larger dogs can have up to a handful per day.

Dog sizeAmount of papaya
Small dog (21–30 pounds)Two to three slices
Medium dog (31–50 pounds)Four to six slices
Large dog (51–90 pounds)A handful of slices
Extra-large dog (91+ pounds)A large handful of slices

Signs Your Dog Might Be Allergic to Cucumbers

Just like us, dogs can have allergies to food too. So, there’s a chance your dog may not tolerate cucumbers well.

To be sure, share cucumbers in small amounts and look out for signs such as:

  • Upset stomach
  • Tummy pain
  • Diarrhea
  • Vomiting

If you notice these symptoms, it’s best to take your pup to the vet and ask for assistance. 

Remember: every dog is unique, and what works for one might not work for another.

4 Ways to Introduce Cucumbers to Your Dog’s Diet

Cucumbers are fantastic on their own, as plain slices. But if you want to get a little creative, here are some fun and healthy ways to treat cucumbers for your dog:

Frozen cucumber chews: You can freeze cucumber slices on a hot day for a cool and refreshing treat.

Cucumber and carrot combo: Combine cucumber and carrot slices for a double dose of crunchy goodness and extra nutrients.

Cucumber and peanut butter: If your dog isn’t allergic to peanuts, try spreading a thin layer of peanut butter on cucumber slices – most dogs love the taste of cucumber and peanut butter.

Cucumber Mint Water: Add cucumber slices and a few mint leaves to your dog’s water bowl – it will be like refreshing spa water for your pup! But be aware that feeding mint leaves to your doggo in excess can cause tummy troubles.

Pro tips: Since dried mint leaves and essential mint oil are much more potent, they can easily cause GI upset in dogs, so opt for fresh leaves instead and only use a leaf or two per day.

Homemade, Dog-Friendly Frozen Dessert With Cucumbers

If you have some time and want to make something more special than just adding cucumbers to your dog’s daily meals, let me show you a quick and simple snack you can make for your pup.


  • 1 fresh cucumber
  • 1/2 cup plain, unsweetened yogurt (opt for any plain yogurt – safe for dogs)
  • 1/2 ripe banana
  • A couple of fresh mint leaves (optional, for extra freshness)


  1. Start by washing and peeling the cucumber – although skin has a lot of fiber, it can be tough to digest, so you should peel most of it off.
  1. Cut the cucumber into small, bite-sized pieces. Remember, we want them to be the right size for your dog. And don’t forget to scoop out the seeds.
  1. In a blender or food processor, mix the cucumber, plain yogurt, banana, and mint leaves (if you’re using them). Blend until you have a smooth, creamy mixture.
  1. Now, grab an ice cube tray or silicone mold. Pour the mixture into the tray or mold, filling each section.
  1. Pop your cucumber dog treats into the freezer and let them chill for a few hours, or until they’re nice and firm.
  1. Once frozen, remove the treats from the tray and store them in an airtight container or a resealable bag in the freezer.

This way, you’ll always have a stash of cool, healthy snacks for your pup!
