Can Dogs Eat Erythritol? The Short Answer

Yes, but with major caveats. Unlike xylitol—highly toxic to dogs—erythritol is generally considered non-toxic. However, that doesn’t mean it’s “safe” in large amounts. Small, accidental ingestions (like a crumb of sugar-free gum) are unlikely to harm your dog, but larger doses can cause uncomfortable gastrointestinal issues.

The bottom line: Erythritol isn’t a nutritional necessity for dogs, and there’s no good reason to feed it to them intentionally. When in doubt, skip the sugar substitutes and opt for dog-safe treats instead.

What Is Erythritol, Anyway?

Erythritol is a sugar alcohol (or “polyol”)—a type of low-calorie sweetener used in thousands of human products, from sugar-free gums and candies to protein bars and baked goods. Here’s what you need to know:

  • Naturally Occurring (Sort Of): Small amounts of erythritol are found in fruits like grapes, melons, and pears, as well as fermented foods like cheese and wine. But the erythritol in commercial products is typically made by fermenting cornstarch.
  • Low-Calorie and Low-Glycemic: It’s about 70% as sweet as sugar but has just 0.2 calories per gram (compared to sugar’s 4 calories per gram). It also doesn’t raise blood sugar or insulin levels, making it popular for diabetics and people watching their weight.
  • “Tooth-Friendly”: Unlike sugar, erythritol doesn’t feed harmful bacteria in the mouth, so it’s often added to oral care products like toothpaste.

For humans, erythritol seems like a win-win. But what about our four-legged friends?

Potential “Benefits” of Erythritol for Dogs (Spoiler: There Are Few)

Let’s cut to the chase: Erythritol offers no nutritional benefits to dogs. Dogs don’t need sweeteners in their diet—their taste buds can detect sweetness, but they don’t crave it like humans do. A balanced dog food provides all the nutrients they need, from protein and fats to vitamins and minerals.

That said, if we stretch the definition of “benefit,” here’s the only upside:

  • Non-Toxic (Unlike Xylitol): Xylitol, another sugar alcohol, is extremely toxic to dogs, even in small amounts (it causes a dangerous insulin surge, leading to hypoglycemia, liver failure, or death). Erythritol, by contrast, doesn’t trigger this reaction. This means accidental ingestion of a sugar-free mint or a crumb of erythritol-sweetened cake is far less risky than xylitol.

But that’s hardly a reason to feed it to your dog on purpose. Think of it this way: Just because something isn’t poisonous doesn’t make it good for them.

Risks of Feeding Erythritol to Dogs

While erythritol isn’t toxic, it can still cause problems—especially if your dog eats too much. Here are the key risks to watch for:

1. Gastrointestinal Upset (The Big One)

Dogs lack the enzymes needed to fully digest sugar alcohols like erythritol. When erythritol reaches the large intestine, gut bacteria ferment it, leading to:

  • Diarrhea
  • Gas and Bloating
  • Stomach Pain or Cramping
  • Nausea or Vomiting (in severe cases)

The severity depends on the dose and your dog’s size. A Chihuahua who steals a handful of sugar-free candy might get very sick, while a Great Dane who nabs a single piece may only experience mild gas.

2. Choking or Intestinal Blockage (From the Product, Not the Erythritol)

Many products containing erythritol—like gum, hard candies, or chewy protein bars—pose a physical risk to dogs. Gum, for example, is indigestible and can get stuck in the throat (choking hazard) or form a blockage in the intestines (which may require surgery to remove).

3. Dehydration (From Diarrhea)

Severe or prolonged diarrhea from erythritol can lead to dehydration, especially in small dogs, puppies, or seniors. Signs of dehydration include dry gums, sunken eyes, lethargy, and reduced urination. If you notice these, contact your vet immediately.

How Much Erythritol Is Safe for Dogs?

There’s no official “safe dose” of erythritol for dogs, but vets and poison control experts have observed patterns:

  • Small Amounts: A few crumbs of a sugar-free cookie or a tiny piece of gum are unlikely to cause issues. Most dogs will pass these with minimal (if any) stomach upset.
  • Moderate Amounts: 0.5–1 gram of erythritol per pound of body weight may cause diarrhea or gas. For a 20-pound dog, that’s 10–20 grams (about 2–4 teaspoons).
  • Large Amounts: More than 1 gram per pound of body weight could lead to severe diarrhea, dehydration, or electrolyte imbalances.

Example: A 10-pound Yorkie who eats a whole pack of sugar-free gum (which often contains 1–2 grams of erythritol per piece) is at risk of significant GI distress.

If your dog eats a large amount of erythritol, monitor them closely for 24 hours. If they develop diarrhea, vomiting, or lethargy, call your vet.

Healthier Alternatives to Erythritol for Dogs

Instead of sharing your sugar-free snacks, treat your dog to these safe, nutritious alternatives:

1. Fresh Fruits (In Moderation)

  • Blueberries: Packed with antioxidants and low in calories.
  • Strawberries: Rich in vitamin C and fiber.
  • Apple Slices (No Seeds!): Crunchy and full of fiber (remove the core, as apple seeds contain trace amounts of cyanide).
  • Bananas: A great source of potassium and natural sugars (feed sparingly to avoid weight gain).

Avoid: Grapes, raisins, cherries, and avocados—these are toxic to dogs.

2. Veggies (Crunchy and Nutritious)

  • Carrots: Low-calorie, high in beta-carotene, and great for dental health.
  • Cucumber: Hydrating and perfect for hot days.
  • Green Beans: Rich in fiber and vitamins (steamed or raw).
  • Sweet Potato: Cooked, mashed sweet potato is a nutrient-dense treat (avoid raw, as it’s hard to digest).

3. Dog-Safe Commercial Treats

Look for treats with simple, whole-food ingredients (e.g., “chicken and sweet potato” or “salmon and rice”). Avoid products with added sugars, artificial flavors, or mystery “by-products.”

4. Homemade Treats

Whip up a batch of dog-friendly cookies using peanut butter (no xylitol!), oats, and pumpkin. Your pup will love them, and you’ll know exactly what’s in them.

FAQ: Your Erythritol Questions Answered

Q: Is erythritol toxic to dogs like xylitol?

A: No. Xylitol causes life-threatening insulin release in dogs, but erythritol does not. However, large amounts of erythritol can still cause GI upset.

Q: My dog ate a sugar-free gum with erythritol. Should I panic?

A: Probably not. Most sugar-free gums contain 1–2 grams of erythritol per piece. A single piece is unlikely to harm a medium or large dog, but a whole pack could cause diarrhea in small breeds. Monitor for 24 hours and call your vet if symptoms appear.

Q: Can puppies eat erythritol?

A: Puppies have sensitive stomachs, so even small amounts of erythritol may cause diarrhea. It’s best to avoid all sugar substitutes for puppies.

Q: Are there dog foods that contain erythritol?

A: No. Reputable dog food brands do not add sweeteners like erythritol, as dogs don’t need them. If you see “erythritol” on a dog food label, it’s a red flag—avoid that product.

Q: Can erythritol cause kidney problems in dogs?

A: There’s no evidence linking erythritol to kidney damage in dogs. The main risk is gastrointestinal upset, not organ failure.

Conclusion: Prioritize Safety and Moderation

At the end of the day, erythritol isn’t a “poison” for dogs, but it’s also not a treat worth sharing. Dogs thrive on a balanced diet of high-quality dog food, plus occasional, safe snacks like fruits, veggies, or homemade treats.

If your dog accidentally ingests erythritol, stay calm—small amounts are rarely dangerous. But if they eat a large quantity or show signs of distress (diarrhea, vomiting, lethargy), contact your vet right away.

As pet parents, our job is to keep our furry friends happy and healthy. When in doubt, skip the human snacks and reach for something that’s actually good for them. Your dog’s tail (and tummy) will thank you!
