Xylitol and Dogs: A Harmful Combination

While xylitol is safe for humans to consume, xylitol and dogs don't go together. Unfortunately, xylitol poisoning in dogs is common, and ingesting even a small amount can be harmful. Let's look at what xylitol is, which products include this ingredient and what to do should your furry friend accidentally consume it.

What Is Xylitol?

Xylitol is a natural sugar alcohol derivative that's used as a sugar substitute in many products, including sugar-free gum, candy, toothpaste, chewable vitamins, peanut butter and more. Fortunately, Preventive Vet provides a comprehensive list of products that contain xylitol. Some brands include:

• Trident and Icebreakers gum
• Go Nuts, Co
• Krush Nutrition
• P28 Foods
• Nuts 'N More
• No Cow
• ACT dental products

Xylitol also comes in a granulated powder that's used for cooking and baking, and it's even used in some sport clothing lines as a cooling agent. This ingredient goes by several other names, including birchbark extract, birch sugar, d-xylitol, xylite, 1,4-anhydro-d-xylitol, anhydroxylitol and xylitylglucoside. As you can see, xylitol is fairly ubiquitous.

Clinical Signs of Xylitol Consumption

Clinical signs associated with xylitol and dogs can develop in as little as 15 minutes after ingestion. Some signs, like low blood sugar, can last for up to 12 hours following exposure. Clinical signs of xylitol poisoning in dogs include:

• Vomiting
• Weakness
• Incoordination
• Seizures
• Bloody diarrhea
• Excessive bruising due to bleeding disorders
• Jaundice

The most common way dogs are poisoned by xylitol is by ingesting sticks of xylitol-sweetened gum. Even two sticks of gum containing xylitol can be enough to cause liver failure in dogs.

Helping Your Dog If They've Consumed Xylitol

If your dog accidentally consumes a product that contains xylitol, intervene quickly. The sooner you can get the xylitol out of your dog, the better the prognosis. Your first step should be contacting your veterinarian for advice on how to proceed. If your vet isn't available, call an emergency veterinary clinic or a vet on call. If you don't have an urgent care vet available, call the Pet Poison Hotline.

When to Visit Your Vet

After consultation with your veterinarian, if they recommend having your pet seen, you should bring them to the hospital as soon as possible for evaluation. If you are able to get your pet to your veterinarian for treatment within 2-3 hours of ingestion, they may be able to induce emesis (vomiting) to try and get the xylitol out of your dog's digestive system. If emesis is unsuccessful, or it's been more than a few hours since the xylitol was ingested, your dog may be hospitalized for monitoring of blood sugars, liver function and general supportive care including fluid therapy to support the vital organs and maintain normal blood sugars. Your dog will likely need to be hospitalized and monitored for at least 24 hours. Dogs who are exposed to xylitol are at risk for liver damage, electrolyte abnormalities, bleeding disorders and low blood sugar, and all of these parameters need to be frequently checked and corrected if necessary.

For most dogs, the prognosis is good with treatment. The prognosis is guarded to poor if severe liver damage occurs.
