Parts of Watermelon Dogs Should Not Eat
Seeds
One or two swallowed seeds are unlikely to cause harm, but many seeds can lead to an intestinal blockage, especially in small dogs. Choose seedless watermelon or remove all the black seeds. The pale, soft seeds in seedless watermelon are generally fine.
Rind
The tough green rind is hard to chew and digest. It can cause vomiting, diarrhea or a blockage. Cut the flesh away from the rind and throw the rind out of your dog’s reach.
Sweetened watermelon products
Skip watermelon candy, flavored drinks, sorbets and anything with added sugar or artificial sweeteners. Xylitol is especially dangerous for dogs.
How Much Watermelon Can a Dog Eat?
| Dog size | Suggested amount |
|---|---|
| Extra small (2-10 lb) | 1-2 small cubes |
| Small (11-25 lb) | 2-3 cubes |
| Medium (26-50 lb) | 4-6 cubes |
| Large (51-90 lb) | 6-8 cubes |
| Extra large (91+ lb) | Up to about 1 cup |
Follow the 10% rule: treats, including fruit, should not be more than 10% of your dog’s daily calories. Too much watermelon can cause diarrhea.
