It’s a scorching summer day – and as you sit down to enjoy a slice of juicy watermelon, your furry friend looks up at you with hope in his eyes. Which naturally begs the question: Can dogs eat watermelon?
The good news: watermelon is one of the dog-safe fruits, as long as you don’t overdo it. I can’t think of a better low-calorie snack in the summertime. But there are crucial safety rules and limitations to bear in mind.
We talked to two veterinarians – Sam Meisler, DVM (PetWellClinic) and Amy Attas, DVM (City Pets), to explain everything you need to know about feeding watermelon to dogs in a safe way.
Is Watermelon Good for Dogs? Nutritional Value of Watermelon for Dogs
Hydration Support
- Watermelon is 92% water, it’s one of many hydrating munchable snacks – and that comes in especially handy during hot summer months or after a day of outdoor play.
Low in Calories
- Half a cup of diced watermelon is about 23 calories, so it’s a waist-friendly food for dogs trying to watch their waistline.
Vitamin & Antioxidant Boost
Watermelon does contain small amounts of good-for-you nutrients, says Dr. Attas:
- Vitamin C – It helps with health in general but dogs already make enough.
- Beta carotene → Vitamin A – supports vision and the immune system.
- Vitamin B6 – necessary for metabolism and the production of red blood cells.
- Lycopene – a natural plant antioxidant that could possibly fight oxidative stress.
These nutrients are not a substitute for a balanced dog food, but may offer some additional nutrition.
Risks and Precautions
While watermelon is safe in moderation, however, there are some important risks to take into account:
- Natural Sugars – While it is not in high quantity, sugar can cause weight gain or be dangerous to diabetic dogs.
- Seeds & Rind – Seeds can obstruct the intestine or pose a choking hazard. The skin is thick, indigestible and may cause an upset stomach.
- Digestive Problems – Oversupply of watermelon or an sudden introduction can lead to diarrhea, bloating, or vomiting.
- Allergies – Uncommon but it is possible. (Indicators include itching, swelling and digestive upset.) Consult your vet if symptoms develop.
How Much Watermelon is Safe for Dogs to Eat?
Veterinarians encourage moderation and abidance of the 10% treat rule (treats are not to exceed 10% of total daily caloric intake).
- Puppies and small dogs: few cubes.
- Medium to large dogs: a few cubes.
Give your dog a small amount to start and see how he reacts.
How to Safely Give Watermelon to Dogs
- Select seedless watermelon – or go ahead and extract the seeds.
- Peel the rind off entirely – never let dogs gnaw on it.
- Cut into bite-sized pieces that are easy to manage to reduce choking hazard.
- Serve it plain – no sugar, salt or seasonings.
- Begin offering one piece at a time, and watch for any sort of reaction.
- Freeze in cubes for a summer treat (let the slices thaw slightly if too hard).
Other Fruits Dogs Can Eat
Watermelon is not the only safe fruit. Other dog-friendly options include:
- Apples (without seeds/core)
- Bananas
- Blueberries & Blackberries
- Strawberries & Raspberries
- Pears (seedless)
- Cantaloupe
- Mango & Papaya
- Kiwi & Cranberries
Steer clear of grapes and raisins – they’re toxic to dogs.
Serving Ideas for Dogs
- Watermelon popsicles: Blend watermelon and freeze in some silicone molds.
- Fruit mix bowl: Add small portions of watermelon, banana and blueberries.
- Hydration cubes: Puree watermelon with water, freeze and pop into your dog’s bowl.

FAQs About Dogs and Watermelon
Q1. Can puppies eat watermelon?
Yes, but you can eat very little of it, and only if it is seedless as well as rind-free. Puppies have more sensitive stomachs, so go slow.
Q2. Can diabetic dogs have watermelon?
No, it’s best avoided. Natural sugar can cause spikes in blood sugar and exacerbate diabetes.
Q3. Is it okay for dogs to eat yellow or seedless watermelon?
Yes. Yellow watermelon is perfectly safe, so far as I know, and seedless watermelon makes the cut because there are no seeds to spit out.
Q4. What if my dog accidentally eats watermelon seeds or rind?
Some seeds will likely pass without problems, but more than one seed or some of the rind can lead to stomach upset or blockages. If your dog is vomiting, lethargic or has cramping in its belly, call your vet.
Q5. How much watermelon can I give my dog?
It’s out of whack to have watermelon each day as a snack. A couple of times a week in the summer is a good rule of thumb.
Q6. Is your dog allowed watermelon juice or flavored stuff?
No. Skip Cheerios’ versions. Too much sugar, artificial sweeteners and/or preservatives. What about watermelon juice, candy or flavored snacks? Nope. Because they add sweetness to them by way of added sugar and natural or artificial (like xylitol) sweeteners that are toxic and preserving agents.
Q7. What is the best way to store watermelon for dogs?
Store leftover cut watermelon in a refrigerator for about 3 days. If you’re looking into long-term storage, freeze bite-sized cubes, and thaw slightly before serving.
