Can Dogs Eat Watermelon? Seeds and Rind
Watermelon is a classic summer snack, mostly water and easy to share. The flesh is generally fine for dogs in small amounts, but the seeds and rind can cause problems, so a little preparation is needed.

Is watermelon safe for dogs?
The red flesh is mostly water, with some vitamins and a little fiber. It is generally safe for dogs in moderation. Because it contains natural sugar, it is a treat. Dogs with diabetes or digestive problems may need to avoid it, so ask your vet.
Seeds and rind
Seeds can add up and may cause a blockage in small dogs, and the tough rind is hard to digest and can cause vomiting or a blockage. Cut the flesh away from the rind, and pick out the seeds or choose a seedless variety.
- Remove the rind completely.
- Take out the seeds.
- Cut flesh into small cubes.
- Start with a couple of pieces.
Serving ideas
Chilled or frozen cubes are a cooling treat in hot weather. Watermelon does not replace fresh water, and dogs should always have water available, especially in warm weather. Extras like this should stay a small part of the day's food. A common vet guideline is that treats and extras make up no more than about 10 percent of daily calories.
What to avoid
Skip watermelon candy, sorbet and cocktails. Alcohol is dangerous for dogs, and sweets often contain sugar or xylitol. If your dog may have eaten something harmful, call your veterinarian, the ASPCA Animal Poison Control Center at (888) 426-4435, or Pet Poison Helpline at (855) 764-7661 straight away. A consultation fee may apply, and it is far cheaper than waiting.
Note: This article is general information, not veterinary advice. Dogs differ by size, age and health, so ask your veterinarian if your dog has a medical condition, is a puppy, or is on a special diet.
Keeping dogs cool safely
In hot weather, watermelon can help a dog take in some water, but it is not a replacement for fresh drinking water, shade and rest. Signs of overheating include heavy panting, drooling, bright red gums, weakness and collapse. These are emergencies, and cooling a dog gently and calling a vet is the right response.
Do not leave a dog in a parked car, and avoid exercise in the heat of the day.
Serving ideas
Chilled watermelon cubes are a good summer snack. You can freeze cubes on a tray, or blend seedless watermelon and freeze it in ice trays.
- Chilled seedless cubes.
- Frozen cubes in an ice tray.
- A little mashed on a lick mat.
- Avoid anything with added sugar or alcohol.
Why seeds and rind cause trouble
A few seeds are unlikely to hurt a large dog, but many seeds can pile up in the gut, particularly in small dogs. The rind is tough, fibrous and hard to break down, and swallowing chunks can cause vomiting or a blockage. If your dog swallows a lot of rind or seeds and then vomits, goes off food or strains to pass stools, call your vet.
Watermelon by dog size
A toy dog can have one or two small cubes, and a large dog a few. Because watermelon is so watery, it feels like a snack of nothing, but the sugar still counts. Portion it out before you start.
Remove every seed, or choose seedless watermelon. If your dog eats a lot, expect loose stools.
Puppies, seniors and health conditions
Puppies can have a cube or two, but too much can cause diarrhea. Senior dogs with kidney problems or on special diets should have watermelon only with their vet's agreement.
Dogs with diabetes should avoid sugary fruit unless a vet advises otherwise. If your dog has a sensitive stomach, start with a single piece.
Common mistakes with watermelon
The most common mistakes are leaving seeds and rind in, and letting a dog eat from a large slice left on the ground at a picnic. Another is assuming it is all water and therefore free. The flesh contains sugar, and large quantities can cause diarrhea.
People also share watermelon cocktails, frozen drinks and sorbet. Alcohol is dangerous for dogs according to the ASPCA, and sorbet may contain xylitol. Keep these away.
Finally, remember that a watermelon treat is not a substitute for proper cooling on a hot day. Shade, rest and cool water come first.
Summer snack safety for dogs
On a summer day, the family snacks may include watermelon, ice lollies, corn on the cob, kebabs and drinks. Some of these are fine for dogs, and others are not. Corn cobs can cause blockages, kebab sticks can injure, and alcohol and sweet drinks are not suitable.
Offer your dog its own cool treat, such as watermelon cubes without seeds, and keep fresh water and shade available. Watch for signs of overheating. Keep bins closed, and supervise your dog around the barbecue.
