Immediate Health Effects

If a horse ingests chocolate, symptoms appear fast. You’ll see signs like rapid breathing and hyperactivity. In severe cases, your horse might get colic or even seizures. Immediate veterinary attention is critical.

Long-Term Consequences

Even if a horse seems okay after eating a small amount, long-term risks exist. Repeated exposure can lead to chronic health issues. These include heart problems and digestive ailments. It’s a gamble not worth taking.

Chocolate as a Banned Substance in Competitions
