On a hot summer day, few things are as refreshing as a juicy slice of watermelon. If you're enjoying this sweet treat and your dog is giving you those pleading eyes, you might wonder: "Can dogs eat watermelon?" The good news is yes, the flesh of watermelon is safe and even beneficial for dogs when served properly. However, there are important guidelines to follow to ensure this summer fruit remains a healthy treat for your canine companion.
Quick Answer
YES: Dogs can safely eat the pink flesh of watermelon.
NO: Dogs should not eat watermelon seeds or rind.
Is Watermelon Safe for Dogs?
Yes, the flesh of watermelon is safe for dogs to eat. Watermelon is non-toxic and can be a healthy, hydrating treat, especially during warm weather. However, not all parts of the watermelon are safe, and there are some important precautions to take when sharing this fruit with your dog.
Health Benefits of Watermelon for Dogs
Watermelon isn't just safe—it's packed with nutrients that can benefit your dog's health:
High Water Content (92%)
Makes watermelon an excellent hydrating treat, especially during hot weather or after exercise
Low in Calories
A good option for dogs on weight management plans
Rich in Vitamins A, B6, and C
Supports immune function, vision health, and overall wellbeing
Contains Potassium
An essential mineral for kidney and heart function, muscle development, and bone health
Source of Lycopene
An antioxidant that may help prevent cancer and reduce inflammation
Contains Fiber
Supports digestive health and regular bowel movements
Watermelon Parts Dogs Should NOT Eat
While the pink flesh of watermelon is safe and healthy, other parts of the fruit can be harmful to dogs:
Watermelon Seeds
The black seeds in watermelon pose several risks to dogs:
- They can cause intestinal blockage, especially in small dogs
- Multiple seeds can accumulate and lead to a serious blockage requiring surgery
- Seeds can cause choking, particularly in small breeds
While a few accidentally ingested seeds might pass through a large dog's digestive system without issue, it's best to remove all seeds before feeding watermelon to your dog. Seedless watermelon varieties are a good option, though they may still contain small white seeds that should also be removed.
Watermelon Rind
The rind (the green outer skin) of watermelon should not be fed to dogs:
- It's tough and difficult to digest
- It can cause gastrointestinal upset, including vomiting and diarrhea
- Large pieces can cause intestinal blockage
- The rind may contain pesticide residues if not organic
While small amounts of the white part of the rind (the part between the pink flesh and the green outer skin) may be less concerning, it's safest to stick with just the pink flesh.
How to Safely Prepare Watermelon for Your Dog
Step-by-Step Preparation
- Wash the watermelon: Rinse the outside of the watermelon thoroughly to remove any surface dirt or residues
- Cut the watermelon: Slice the watermelon in half and then into manageable pieces
- Remove all seeds: Carefully remove all black and white seeds from the flesh
- Cut away the rind: Remove all of the green outer skin and white rind
- Cut into appropriate sizes: Dice the seedless flesh into bite-sized pieces appropriate for your dog's size to prevent choking
Creative Ways to Serve Watermelon to Your Dog
Once properly prepared, you can serve watermelon to your dog in several ways:
Fresh Cubes
Simple bite-sized pieces as an occasional treat
Frozen Chunks
Perfect for hot days as a cooling treat
Pureed Watermelon
Blend and freeze in ice cube trays for "pupsicles"
Watermelon and Yogurt Pops
Mix pureed watermelon with plain, unsweetened yogurt and freeze
How Much Watermelon Can Dogs Eat?
While watermelon is safe and nutritious, it should be given in moderation. Treats, including fruit, should make up no more than 10% of your dog's daily caloric intake.
Recommended Serving Sizes
Small dogs (under 20 lbs)
1-2 one-inch cubes
Medium dogs (20-50 lbs)
3-4 one-inch cubes
Large dogs (over 50 lbs)
5-6 one-inch cubes
Start with a small amount to see how your dog reacts, especially if it's their first time trying watermelon. Some dogs may have sensitive digestive systems that require smaller portions.
Potential Risks of Feeding Watermelon to Dogs
While the flesh of watermelon is generally safe for dogs, there are some potential risks to be aware of:
Digestive Upset
Too much watermelon can cause digestive issues in some dogs, including:
- Diarrhea
- Stomach discomfort
- Gas
This is typically due to the high fiber and water content and is more likely if your dog consumes large quantities.
Sugar Content
While watermelon contains natural rather than added sugars, it still has a relatively high sugar content that could be problematic for certain dogs:
- Dogs with diabetes: Should only have very small amounts, if any, and only with veterinary approval
- Overweight dogs: Should have limited access to high-sugar treats, including watermelon
- Dogs with certain health conditions: Such as pancreatitis may need to avoid watermelon
Allergic Reactions
While rare, some dogs may be allergic to watermelon. Signs of an allergic reaction can include:
If you notice any of these symptoms after your dog eats watermelon, contact your veterinarian immediately.
