Watermelon is mostly water with a little natural sugar and fiber. It can be a refreshing snack alongside a complete diet. Keep treats/topper foods to about the 10% rule of daily calories.
Safe prep tips
- Choose seedless when possible. If using regular watermelon, remove all seeds.
- Skip the rind: it’s tough to chew and digest and can be a choking/GI upset risk.
- Cut small: tiny cubes for small dogs/puppies; always supervise.
- Plain only: no salts, seasonings, syrups, or “watermelon-flavored” products.
How much should I give?
Start with a few small cubes and see how your dog handles the extra fiber and natural sugars. Larger dogs can have a small handful of bite-size pieces; smaller dogs just a few bites.
Ask your vet first if your dog has diabetes, pancreatitis, kidney issues, or is on a prescription diet.
Easy ways to serve watermelon
- Chilled cubes for a quick summer snack.
- Frozen bites: purée and freeze in a silicone mold (plain; no sweeteners).
- Lick-mat topper: a thin spread of plain purée; keep portions modest.
What to avoid
- Seeds: remove them—seeds can pose a blockage risk, especially for small dogs.
- Rind: tough to chew/digest and can cause GI upset.
- Watermelon-flavored products: candy, drinks, or gum may contain xylitol (toxic to dogs) or excess sugar. Stick to plain fruit.
If your dog ate seeds or rind
Monitor for vomiting, reduced appetite, or straining. Contact your veterinarian if you’re concerned, especially for small dogs or if a large amount was eaten.
