Why are marshmallows dangerous for dogs?

Marshmallows are dangerous primarily due to the potential presence of Xylitol, an artificial sweetener that is highly toxic to dogs. Even a small amount of Xylitol can cause a rapid drop in blood sugar and liver failure. Additionally, the extremely high sugar and gelatin content in regular marshmallows can lead to digestive upset, obesity, and acute pancreatitis.

My dog ate one regular marshmallow, should I be worried?

If it was a single, standard sugar marshmallow without Xylitol, your dog will likely be fine, though they may experience a mild stomach ache or diarrhea. However, you must immediately check the ingredient list for Xylitol (sometimes listed as birch sugar). If Xylitol is present, or if your dog is small or has underlying health issues like diabetes, contact your veterinarian immediately.
