Symptoms of Xylitol Poisoning in Dogs: Early Signs & Treatment

Xylitol is a common artificial sweetener found in many sugar-free human products such as chewing gum, toothpaste, peanut butter, vitamin supplements, and baked goods. While safe for people, xylitol is highly toxic to dogs and can lead to severe health issues or even death if ingested.

Because dogs are naturally curious and attracted to sweet flavours, accidental ingestion of xylitol-containing products is a frequent cause of emergency veterinary visits across the UK. This article explains why xylitol is poisonous to dogs, how much can be dangerous, typical symptoms to watch for, and what you should do if your dog has eaten it.

Why Is Xylitol Poisonous to Dogs?

Unlike humans, a dog's body responds to xylitol by releasing a large amount of insulin from the pancreas. This causes a rapid and dangerous drop in blood sugar levels (hypoglycaemia), which can lead to weakness, disorientation, seizures, and collapse. In some cases, xylitol ingestion can also result in acute liver failure, though the exact cause of this liver damage is still not fully understood by veterinary researchers.

What Amount of Xylitol Is Toxic?

Dogs are extremely sensitive to xylitol, and even a tiny amount can trigger poisoning. A dose as low as 0.1 grams per kilogram of body weight can cause hypoglycaemia. For smaller dogs such as a Yorkshire Terrier puppies, just one piece of sugar-free gum containing xylitol may be enough to cause symptoms.

How Are Dogs Most Likely to Consume Xylitol?

Xylitol is most commonly found in sugar-free chewing gum and toothpaste, which are frequent ingestion sources for dogs. It can also be present in sugar-free candies, baked goods, sugar-free peanut butter (a popular treat for dogs), and vitamin supplements. Items left within reach, such as gum tucked into pockets or bags, pose a significant risk.

What Are the Symptoms of Xylitol Poisoning in Dogs?

The symptoms of xylitol poisoning in dogs can develop quickly—often within 10 to 60 minutes—but may be delayed up to 18 hours depending on factors like product type and dog size. Early signs include:

• Vomiting, often with traces of the ingested product
• Lethargy and unusual tiredness
• Weakness or difficulty standing and walking
• Confusion or disorientation
• Excessive drooling and nausea

If untreated, symptoms can worsen to:

• Tremors and seizures
• Collapse or difficulty breathing
• Loss of bladder and bowel control
• Coma or unconsciousness

What To Do If Your Dog Has Eaten Xylitol

If you suspect your dog has eaten any amount of xylitol, contact your vet immediately, even if your dog is not yet showing symptoms. Prompt veterinary care significantly improves the chances of full recovery.

At the vet, treatment might include carefully inducing vomiting to remove xylitol from your dog's stomach, administering intravenous fluids and glucose to correct hypoglycaemia, monitoring liver function, and addressing seizures if necessary. Do not attempt to induce vomiting at home without vet guidance as it may worsen the situation.

Prevention Tips for Keeping Dogs Safe From Xylitol

• Store all xylitol-containing products well out of your dog's reach, including sugar-free gums, candies, peanut butter, and oral hygiene products.
• Educate family members and visitors about the dangers of xylitol to dogs.
• Dispose of gum and other packaging securely.
• Be vigilant during holidays and social occasions when unusual foods may be around.
• Consider dog-safe treats and alternatives for your pet.

Summary

Xylitol poisoning in dogs is a rapid and serious condition characterised by symptoms such as vomiting, lethargy, weakness, disorientation, seizures, and potentially coma. Even very small doses can be fatal, especially in smaller breeds like the Yorkshire Terrier. Immediate veterinary attention is crucial for the best outcome.

By understanding the risks and symptoms and practising good prevention at home, dog owners can protect their beloved pets and act swiftly should an accident occur.
