30 LB / 13.6 KG DOGReviewed May 2026
How Much Watermelon Can a 30 lb Dog Eat?
A 30 lb (13.6 kg) dog can safely have 40 to 50 g of seedless watermelon per day, or roughly 4 to 5 cubes of 1.5 cm each. Below is the working, the serving table, and the medium-breed considerations.
The Math
- Daily calorie need: A 30 lb adult dog typically needs 500 to 650 kcal per day, depending on activity.
- Treat allowance (10 percent): 50 to 65 kcal per day.
- Watermelon density: 30 kcal per 100 g (USDA NDB 09326).
- Maximum watermelon if only treat: 165 to 215 g per day.
- Sensible daily serving (leaving room for other treats): 40 to 50 g, or 4 to 5 cubes of 1.5 cm.
