Cucumbers are a yummy, crunchy, and hydrating treat (they’re 95% water!) that make a satisfying summertime snack. But can dogs eat cucumbers? Yes, they can—and in fact, they’re a great low-calorie, low-sugar treat option with several health benefits.
We spoke with Michael Robinson, DVM, owner of PACK Animal Care in Lorton, Virginia, for tips and advice on how to safely include cucumber in your pup’s diet.
Before introducing any new food into your dog’s diet, always check with your veterinarian.
Key Takeaways
- Cucumbers are a hydrating, low-calorie treat for dogs when served fresh, plain, and in moderation.
- While nutritious, cucumbers should be peeled and cut into small pieces to avoid digestive issues or choking hazards.
- Talk to your veterinarian before introducing cucumber into your dog’s diet and watch for signs of digestive upset if your dog eats too much.
Can Dogs Have Cucumber?
Yes, dogs can safely eat cucumber, as long as it’s fresh, plain, and served in moderation.
Regular garden cucumbers are a safe and healthy snack for most dogs. English cucumbers (the long, seedless kind) are also a great option, especially since they’re easier to digest and have thinner skin.
Steer clear of pickled cucumbers, though. Pickles often contain added salt, vinegar, spices, and sometimes garlic or onion—all of which can be harmful to dogs. Similarly, avoid flavored or seasoned cucumber snacks.
Is Cucumber Good for Dogs?
When prepared properly and fed in moderation, cucumber can be a hydrating, low-calorie treat that supports your dog’s overall health. Here’s how:
- It’s 95% water, making it a very hydrating snack.
- It’s a low-calorie treat option. One cup of cucumber has less than half the calories of a typical biscuit dog treat.
- It’s low in sugar, making it an excellent treat option for dogs with diabetes.
- It’s an excellent source of vitamins K, B, and C, as well as potassium and magnesium. These nutrients help promote a strong immune system, healthy muscles and bones, and proper energy metabolism, all of which are important for maintaining your dog’s vitality and well-being.
Is Cucumber Bad for Dogs?
But is cucumber safe for dogs? While it can be a healthy snack, there are a few potential risks to keep in mind when feeding it to your dog:
- Too much cucumber can cause digestive upset, like diarrhea or stomach discomfort, just like any new food.
- The tough skin and seeds may be hard for some dogs to digest and could potentially cause choking or intestinal blockage, especially in smaller breeds.
- In rare cases, dogs may be sensitive or allergic to cucumbers, which could lead to itching, swelling, or other allergic reactions.
How Much Cucumber Can My Dog Eat?
Cucumber should be considered a treat, not a dietary staple. And all treats combined should make up no more than 10% of your dog’s diet. The rest should come from a complete and balanced dog food.
As with any “human” food, you should always consult with your vet before serving cucumber to your dog to determine the right portion size based on your dog’s health status. That said, here are general recommended serving sizes based on your dog’s weight.
| Dog Size | Serving Size | Frequency |
|---|---|---|
| Extra-small dogs (2–10 pounds) | 1–2 bite-size pieces | Once a day |
| Small dogs (11–20 pounds) | 2–3 bite-size pieces | Once a day |
| Medium dogs (21–50 pounds) | 3–4 bite-size pieces | Once a day |
| Large dogs (51–90 pounds) | 4–5 bite-size pieces | Once a day |
| Extra-large dogs (91+ pounds) | 5–6 bite-size pieces | Once a day |
How To Safely Feed Cucumbers to Your Dog
While dogs and cucumber generally go well together, it’s important to prepare them properly to avoid any digestive issues. Dr. Robinson advises taking the following precautions when feeding it to your dog:
- Wash first. Store-bought cucumbers are coated with a wax layer to improve their shelf life. While harmless, the wax can sometimes trap bacteria. Even though you will peel the cucumber, this is still an important step.
- Peel the skin. While cucumber skin is not harmful to dogs, some pups, especially those with a sensitive stomach, may find thick cucumber skin difficult to digest.
- Remove the seeds. Cucumber seeds do not contain any toxins that are harmful to dogs, but they may cause an upset tummy if your dog has a sensitive digestive system. Removing them can help minimize the risk of gas or upset stomach.
- Cut into bite-size pieces. Large pieces can pose a risk of choking or intestinal blockage. Cut cucumber into thin rounds or small chunks, especially for puppies or small dogs. Never feed your dog a cucumber whole.
- Serve plain. Skip any seasoning or dressing. Dogs don’t need the extras, and some ingredients (like garlic or onion powder) can be harmful.
Once you’ve safely prepped the cucumber, you can serve it several ways:
- Straight up: Raw cucumber has the crunch most dogs love.
- As a pureed, frozen treat: You can also freeze pureed cucumber (on a lick mat such as the Frisco Silicone Lick Mat, for example) to give your pup an extra challenge, especially if they get bored easily. This is an extra-nice treat on a hot summer day.

My Dog Ate Too Much Cucumber—What Do I Do?
If your dog managed to eat too many cucumber slices, don’t panic—but do keep an eye out for signs of digestive upset. Too much cucumber can lead to symptoms like:
- Vomiting
- Diarrhea or loose stools
- Excessive gas
- Abdominal discomfort or bloating
- Decreased appetite
In most cases, these symptoms will pass on their own within a day. During that time, make sure your dog has access to fresh water and monitor them closely for any changes in behavior.
If the symptoms are severe, last longer than 24 hours, or your dog seems especially lethargic or uncomfortable, call your veterinarian.
