Safety Summary

Why

Watermelon is a refreshing, safe summer treat for horses. Both the flesh and the rind are safe — the rind actually provides useful fiber. Seeds are generally fine in the quantities present in a normal piece of watermelon. Watermelon's high water content makes it a great treat on hot days. High sugar means moderation for metabolic horses.

Portion Guidance

A few large slices on a hot day. Occasional treat, not daily.

Risks & Symptoms
