Yes, horses can have watermelon. All parts of a watermelon are considered safe for most healthy horses to eat, including the flesh, seeds, and rind. However, keep in mind that watermelon may be safer for some horses than others. “If you have a horse [who] doesn’t chew carefully, I worry about the rinds,” says Merle DerVartanian, DVM, of Conejo Valley Equine in Thousand Oaks, California. “I, luckily, haven’t seen a patient who choked on a piece of watermelon rind, but I would definitely not feed large pieces of watermelon rind to a horse with compromised teeth.” Store-bought watermelon-flavored treats for horses, like Uckele Equi Treats Watermelon Basil Pellets, are also a safe way for horses to enjoy watermelon. ,There’s nothing more refreshing than a slice of cold watermelon on a hot day—and your horse probably agrees. Most horses love the smell and taste of watermelon. But can horses eat watermelon? Yes! Watermelon is a safe treat for horses, although it should not replace any part of a horse’s normal diet. Like all sugary horse treats, watermelon is best fed in moderation. Before introducing any new food into your horse’s diet, always check with your veterinarian.
