Horses love to eat treats of almost any kind. Marshmallows are safe to feed horses in moderation.
Marshmallows are not what you would call healthy, but they are not overwhelmingly unhealthy either.
Since marshmallows contain a significant amount of sugar, horses that suffer from insulin-resistant diseases should not eat them.
Making homemade treats for your horses is not only a fulfilling experience, but also the best way to monitor your horse’s diet.
Horses can safely eat sweet marshmallows in moderation. There is nothing toxic about sweet marshmallows when it comes to horses, if the horse can process sugars naturally.
