Safe in Moderation
Plain marshmallows are not generally toxic to dogs in small amounts, but they are mostly sugar and some sugar-free products may contain xylitol.
- High Sugar/Calories
- Ingredient-Dependent
Safe part
If given at all, a very small amount of a plain marshmallow containing no unsafe ingredients.
Avoid
Sugar-free marshmallows containing xylitol and products containing chocolate or other potentially toxic ingredients.
Preparation
Check the ingredient list, especially for sugar-free products.
Serving guidance
Very small amounts occasionally, if at all.
Nutritional note
Marshmallows are high in sugar and calories and provide little nutritional value.
Did your dog already eat some?
A small amount of an ordinary marshmallow is generally not concerning. If the product contained xylitol, contact a veterinarian or pet poison service promptly.
Why we say this
Ordinary marshmallows are primarily sugar and provide little nutritional value. The major concern is ingredient variation, particularly sugar-free products containing xylitol.
