Can Dogs Eat Watermelon? Yes

Why it’s safe

Watermelon flesh is soft, low in calories and about 92% water, so it makes a light, refreshing snack. Nothing in the red flesh is toxic to dogs.

The parts to avoid are the rind and the seeds. The rind is hard to digest and can cause an upset stomach or an obstruction, especially in large pieces. A large number of swallowed seeds can cause an intestinal blockage, and seeds are also a choking risk, particularly for small dogs. Choose a seedless melon or pick every seed out before serving.

Because watermelon contains natural sugar and fiber, too much can cause stomach discomfort or diarrhea. Offer it as an occasional treat rather than a daily staple, and start with a few pieces to see how your dog's stomach copes. Ask your vet first if your dog has diabetes or is on a weight-loss plan.

Benefits

High water content makes it a cooling treat in warm weather
Soft and low in calories
Easy to cut into bite-sized pieces

Risks

Rind and swallowed seeds can cause choking or intestinal blockage
Too much can cause diarrhea or an upset stomach
Natural sugar adds up for overweight or diabetic dogs

How to serve it safely

Cut the flesh away from the rind, remove every seed, and slice into bite-sized cubes sized for your dog's mouth. Serve fresh or frozen, and keep treats to no more than 10% of daily calories.

Small dogs: a few small cubes
Medium dogs: a few more cubes
Large dogs: a somewhat larger portion, still as an occasional treat

Frozen seedless pieces make a cooling snack in summer, but supervise gulpers. Do not share watermelon-flavored candy, drinks or anything with added sugar or xylitol.

If your dog already ate it

If your dog swallowed a few seeds or a small piece of rind, watch closely. A large number of seeds or large pieces of rind can cause a blockage. Call your vet promptly if you see repeated vomiting, a swollen or painful belly, lack of appetite, straining to poop or no stools, or lethargy.

If a large amount of rind or seeds was eaten, or your dog is small, call your vet for advice. Do not try to make your dog vomit at home. In the US you can also reach ASPCA Animal Poison Control at (888) 426-4435 or Pet Poison Helpline at (855) 764-7661 (fees may apply); elsewhere, contact your local emergency vet.
