Can Dogs Eat Marshmallows?
🟠 Best avoided
Best avoided. Marshmallows are pure sugar with no benefit, and sugar-free ones may contain toxic xylitol.
How much is okay?
One plain marshmallow won't poison your dog, but there's no reason to share them.
Symptoms to watch for
- •If sugar-free with xylitol: weakness, vomiting, collapse — this is an emergency
If your dog already ate it
If the marshmallows were sugar-free or you're unsure, check for xylitol and call your vet or a poison hotline right away.
Safer treats to give instead
Frequently asked questions
