I know it seems crazy. Who gives their dogs marshmallows anyway? But a quick search shows that there are over 12,000 Google searches per month on “Can Dogs Eat Marshmallows.” 

The safest, shortest answer is no, dogs cannot eat most marshmallows. There are a wide range of brands on the market, and the simple fact is that a majority of them contain at least one ingredient that is toxic or harmful to dogs.

Keep scrolling to find out 2 kinds of marshmallows that are safer for dogs. I’m not saying that any marshmallows are good for dogs but at least these won’t send them to the hospital.

Why Can’t Dogs Eat Marshmallows?

There are a few reasons why dogs should not eat marshmallows. Beyond the basic ingredients, marshmallows are extremely unhealthy.

But Can dogs eat marshmallows that are entirely free of the bad stuff? Yes, if you find the right ones. If you take a 100 calorie marshmallow from a pet-safe, xylitol-free marshmallow brand, you’ll find that 97 calories will be nothing but sugar and filler!

For both dogs and people, a treat that’s 97% fluff isn’t healthy. Just as we, as humans, need to moderate our own diets, we need to do the same for our pets.

However, in the quest to determine whether or not dogs can eat marshmallows, it’s useful to understand why they shouldn’t. Here are 5 reasons.

1. Xylitol

xylitol is in most marshmallows and it's toxic to dogs.
xylitol is toxic to dogs.

The most immediate cause for concern when feeding your dog marshmallows is xylitol. This substance is classified as a natural sweetener and is commonly used as a replacement for sugar. For humans, this offers us the chance to enjoy something sweet without the known ramifications of excessive sugar intake, but the same is not true for our canine companions.

The Food and Drug Administration has released a comprehensive explanation of why xylitol is toxic to pups. Unlike people, when dogs digest xylitol, it causes a massive and rapid release of insulin into their blood. As a result, the dog’s blood sugar drops. This is known as hypoglycemia, and it sets in 10–60 minutes after xylitol is first ingested.

In addition to marshmallows, there are an array of products that contain xylitol, including:

  • Mouth wash
  • “Reduced fat”, “no sugar”, and “sugar-free” variants of sweet treats
  • Some toothpaste
  • Some brands of peanut butter
  • A large amount of “diet” foods
  • Breath mints and chewing gum
  • Sugar-free desserts, particularly “skinny” ice cream

Symptoms of Xylitol Poisoning

It doesn’t take a lot of xylitol to endanger the life of your beloved buddy! If your dog ever eats anything that may contain xylitol, such as a marshmallow, it’s best to act first and worry later. Even before symptoms appear, it’s best to call poison control or a veterinarian. The symptoms of xylitol poisoning in dogs are:

  • Vomiting
  • Lethargy
  • Lack of appetite
  • Sudden collapse
  • Difficulty walking

2. Sugar & Corn Syrup

corn syrup is a common sweetener is marshmallows. It's not toxic for dogs but not super healthy

Marshmallows that do not contain xylitol will often contain sugar or corn syrup. While neither of these ingredients are necessarily toxic to dogs, they’re certainly not healthy! Dogs, like people, need to have a balanced diet, and marshmallows do not factor into a well-rounded puppy meal plan.

Should Dogs Eat Sugar?

While a well-rounded canine diet will typically include some sugar, this sweet flavoring is not something that should be artificially introduced. As with people, a sweet-toothed dog risks familiar ailments such as cavities, obesity, and diabetes. Prolonged exposure to excessive sugar can even cause metabolic changes in a dog, which may result in altered moods and energy levels.

Should Dogs Eat Corn Syrup?

Corn syrup poses the same risks as sugar. Dogs with an excessive amount of corn syrup in their diet are just as prone to diabetes and weight gain as dogs with excessive sugar.

Both sugar and corn syrup are technically safe for dogs to eat. In exceedingly small amounts, it is fine to feed your dogs sugar and corn syrup, but it should never be provided in excess. Larger dogs will be able to handle more than small dogs, but all dogs must be closely monitored for signs of diabetes and hypoglycemia.

3. Artificial Flavors & Dyes

Another thing to watch out for is artificial coloring. There are a variety of brands on the market that mix a bit of flavoring into their marshmallows. In some cases, they may even dye the marshmallows different colors. While these components, often labeled with names such as “Red 40” or “Blue 2”, are not necessarily harmful, they’re not something you want your dog to ingest in excess.

Similarly, there are some brands and varieties of marshmallows that contain artificial flavoring. Again, most of these ingredients are safe. However, you don’t want your dog chewing on something that’s packed with artificial flavors and chemicals.

4. Preservatives

There are some chemicals, like xylitol, that are perfectly safe for humans but harmful to dogs. Three major marshmallow preservatives fall into this category: BHA, BHT, and ethoxyquin. All three of these products are and have been used to boost the shelf life of marshmallows, which are prone to rapid hardening and spoilage without additional preservatives.

It should be noted that these preservatives make up an extremely small portion of a marshmallow’s ingredients. In fact, per federal regulations, ethoxyquin can be no more than 0.5% of a marshmallow’s total composition. Nonetheless, it’s often safer to avoid these ingredients altogether.

If a dog consumes an excessive amount of marshmallows, that small percentage can add up. All three of these preservatives are known to exacerbate allergies. Studies suggest that BHA, BHT, and ethoxyquin may even cause dogs to develop new allergies.

5. Choking Risk

Even a perfect marshmallow that meets every requirement to be dog-friendly will have one final trick up its sleeve. Unless properly cut up and served as tiny bite-sized pieces, many marshmallows pose a huge choking risk for dogs. For particularly small dogs and toy breeds, even a miniature marshmallow can be a choking hazard.

What to Do If Your Dog Eats A Marshmallow WIth Xylitol?

If in the process of baking something, your dog scoops up a few miniature xylitol-free marshmallow, it isn’t an emergency. If your dog eats any amount of xylitol, it is automatically a veterinary emergency.

Call Your Vet

Should your beloved pooch eat more than a few marshmallows in a single sitting, then the best course of action is to consult with a veterinarian. While it is preferable to call your veterinarian, any available professional is a valid choice.

Remember: never try and treat the problem yourself! You are likely to do far more harm than good. In addition to the stress this will cause your pet, trying to medicate or treat your dog alone is likely to result in injuries to both parties.

Call the Pet Poison Hotline

If no vets are available to help, then it’s time to try another resource. The Pet Poison Hotline is an amazing resource, and it operates 24/7. They may be reached at (855) 764-7661. When contacted, their expert team will walk you through what to do and how to address the issue. This may involve bringing your dog to a professional all-hours emergency clinic.
