Xylitol Poisoning in Dogs 2025: A Deadly Risk Hiding in Gum, Peanut Butter & Toothpaste 🧴🦷

By Dr Duncan Houston BVSc, Ask A Vet Blog
Published: July 7, 2025

Xylitol—also labeled as birch sugar—is a sweetener commonly found in sugar-free gum, toothpaste, baked goods, and even some peanut butters. But what’s harmless (and even healthy) for humans can be lethal for dogs. In this critical 2025 update, we break down everything you need to know about xylitol toxicity 🐕💀.

⚠️ What is Xylitol?

Xylitol is a natural sugar substitute that helps humans reduce cavities, control diabetes, and manage weight. It’s found in:

• 🧼 Sugar-free gum & mints
• 🦷 Toothpaste & mouthwash
• 🥜 Certain peanut butters (especially protein-boosted brands)
• 🍪 Sugar-free cookies & desserts
• 💊 Supplements, nasal sprays & chewable vitamins

Sounds healthy for us—but dangerous for dogs. Even a small amount can lead to seizures, liver failure, or death. ☠️

🧬 Why Is It So Toxic to Dogs?

Dogs’ pancreases react to xylitol like it’s real sugar, releasing insulin—but 3–7 times more than needed. This causes a sudden plunge in blood sugar (hypoglycemia), which can be fatal.

But that’s not the only danger. In higher doses, xylitol can cause liver necrosis, where liver tissue dies rapidly. This can result in internal bleeding, seizures, coma, and death.

🚨 Symptoms of Xylitol Poisoning

Symptoms can appear in 30 minutes—or up to 12 hours depending on how it was ingested. Common signs include:

• 🤮 Vomiting
• 😵 Weakness, wobbling, or disorientation
• 🐶 Tremors or twitching
• ⚡ Seizures
• ❄️ Cold body temperature
• 🩸 In cases of liver failure: jaundice, bleeding, collapse

📏 How Much is Too Much?

Xylitol is toxic to dogs at 0.03–0.045g per pound of body weight. Many sugar-free gums have 0.009–0.3g per piece. That means:

• 🐾 1–2 pieces of gum can poison a 10 lb dog
• 🐾 1 tbsp of xylitol-sweetened peanut butter can be lethal

Some gums (like Orbit strawberry mint) have over 0.3g per piece. Always check labels and bring packaging to your vet for accurate dosing.

🩺 Treatment and Emergency Care

🚑 If you suspect your dog ingested xylitol, do not wait for symptoms. Call your vet or Ask A Vet immediately and take these steps:

1. 🕐 Get to a veterinary hospital within 30 minutes
2. 🤮 Induce vomiting only if instructed
3. 💉 IV sugar (dextrose) drip for 24 hours
4. 🧪 Monitor liver enzymes, clotting factors, potassium

If liver damage occurs, intensive care and transfusions may be needed. Many dogs recover if treated early, but those with liver necrosis may not survive. ⛔

🐱 What About Cats?

Luckily, xylitol is not toxic to cats. But feline exposure is still discouraged, as research is limited and side effects are unknown. ❓

🦴 What About Pet Dental Products?

Some pet dental rinses and water additives contain safe amounts of xylitol. Always follow dosing guidelines and check with your vet before use. Accidental over-consumption (i.e., drinking a whole bottle) could still be toxic. 🧪

📋 Xylitol Products That Can Harm Dogs

• Orbit, Ice Breakers, Trident gum
• Natural sweetened peanut butters (bodybuilding brands)
• Toothpastes & nasal sprays
