Foods & Products That Contain Xylitol | Pet Safety

Given the growing popularity of sugar-free foods, you have likely heard of xylitol. While this artificial sweetener offers many health benefits to humans, it is highly toxic and potentially deadly for pets. Research indicates that xylitol toxicity in animals can occur at very low doses—sometimes less than one stick of gum.

Upon ingestion, xylitol can cause a severe drop in your pet’s blood sugar levels. In dogs, xylitol stimulates the pancreas to secrete excessive amounts of insulin, which causes hypoglycemia (low blood sugar) to occur.

Clinical signs may include:

• Vomiting
• Lethargy and weakness
• Incoordination or stumbling
• Muscle twitching
• Disoriented behavior
• Seizures

Depending on the amount ingested, animals can even suffer life‑threatening liver damage.

Like most toxins, the effects of xylitol are dose-dependent and can be treated successfully if caught early. If you suspect ingestion, seek veterinary care immediately. Quick intervention is crucial for recovery.

Being proactive is key to protecting your pets—what’s sweet for us is not always sweet for them! Here are some common consumer products where xylitol may be hiding:

Sugar-Free Candy and Gum

Gum is notorious for containing xylitol. Amounts differ from brand to brand, but in some cases, one stick of sugar-free gum can be lethal. Mints, candy and chocolate contain the substance as well. Never let your pet have access to these products.

Xylitol in Oral Care and Personal Hygiene Products

Oral care and personal hygiene products are among the most common — and most overlooked — sources of xylitol in the average household. Because these items sit on bathroom counters, in purses, or in nightstand drawers, they're far more accessible to a curious dog or cat than most pet parents realize.

Common Oral Care Products That Contain Xylitol

Xylitol is a go-to ingredient in human oral care because it actively discourages the bacteria that cause tooth decay. That makes it appealing to manufacturers — and makes the following product categories worth knowing by name:

Always read the ingredient label. Xylitol may also appear under the name "birch sugar" or "wood sugar" on some product labels.

Why These Products Are Especially Risky

The danger isn't just what these products contain — it's how they're stored and how they smell. Flavored toothpastes and minty breath strips can smell appealing to a dog, who may chew through packaging to get to them. Even a small amount of xylitol from a single piece of gum or a partial tube of toothpaste can cause a serious toxic response in dogs, according to the ASPCA Animal Poison Control Center https://www.aspca.org/pet-care/animal-poison-control.

Cats are generally less likely to seek out sweet-tasting items, but they can still be exposed if a product spills or if they groom themselves after walking through a contaminated area https://www.vet.cornell.edu/departments-centers-and-institutes/cornell-feline-health-center/health-information.

The Golden Rule: Human Products Are Never Pet Products

Never use human oral care products on your dog or cat. Human toothpastes — including "natural" mint varieties — are formulated for people who spit and rinse. Dogs and cats swallow what goes in their mouths, which means even a xylitol-free human toothpaste can contain fluoride or other ingredients that aren't appropriate for pets https://www.aspca.org/pet-care/animal-poison-control.

Always choose toothpastes, rinses, and dental gels that are specifically formulated and labeled for dogs or cats. You'll find a range of pet-safe dental care options at Petco.

Storage Tips to Keep Pets Safe

• Store all oral care products in a closed cabinet or drawer — not on an open counter.
• Never leave gum, mints, or breath strips in a coat pocket, tote bag, or backpack on the floor.
• After using mouthwash, rinse the sink and don't leave residue in a cup your pet could access.
• Treat a chewed or missing product as a potential emergency: contact your veterinarian or the ASPCA Animal Poison Control Center immediately if you suspect your pet has ingested any xylitol-containing product https://www.aspca.org/pet-care/animal-poison-control.

If you're ever unsure whether a product your pet got into contains xylitol, bring the packaging with you to the vet — or read the ingredient list aloud to the poison control specialist. Speed matters.

There is not much research available on cats and xylitol. Some speculate that cats are simply pickier about what they eat and are therefore less likely to be exposed. Alternatively, the lack of confirmed cases of xylitol toxicosis in cats may have something to do with their metabolism. However, as we’ve seen with dogs, exposure to xylitol can be deadly. Therefore, the recommendation remains to keep xylitol out of reach from all furry friends, including cats.

Common Products That Contain Xylitol: Risk at a Glance

The table below maps the most frequently reported xylitol-containing product categories to their typical risk level for dogs and cats. Use it as a quick reference — and always read ingredient labels before letting your pet anywhere near a human product.

How to read the risk levels:

• Critical — Even a small amount can cause life-threatening hypoglycemia or liver failure in dogs; treat any exposure as an emergency.
• High — Xylitol is commonly present and exposure is realistic; keep strictly out of reach.
• Moderate — Xylitol may or may not be present depending on the brand or formulation; always check the label.

If your pet has ingested any product from this table, contact your veterinarian or the ASPCA Animal Poison Control Center immediately. Do not wait for symptoms to appear — early intervention is critical to a successful outcome. https://www.aspca.org/pet-care/animal-poison-control

Frequently Asked Questions

How much xylitol is toxic to a dog? Xylitol toxicity in dogs is dose-dependent, and dangerous effects can occur at very low amounts — in some cases, less than a single stick of sugar-free gum is enough to cause hypoglycemia in a small dog. Because safe thresholds vary by a dog's body weight and the concentration of xylitol in the product, any suspected ingestion should be treated as an emergency. Contact your veterinarian or a poison control hotline right away. https://www.aspca.org/pet-care/animal-poison-control

What are the signs of xylitol poisoning in dogs? Clinical signs can appear within 15–30 minutes of ingestion and may include vomiting, lethargy, weakness, loss of coordination or stumbling, muscle twitching, disoriented behavior and, in severe cases, seizures. Depending on the amount consumed, life-threatening liver damage is also possible. If you observe any of these signs — or even suspect exposure — seek veterinary care immediately rather than waiting to see if symptoms worsen. https://www.aspca.org/pet-care/animal-poison-control

Is xylitol toxic to cats? Research on xylitol toxicity in cats is limited. Cats may be less frequently exposed because they tend to be more selective about what they eat, and their metabolism differs from dogs. However, because the potential for harm exists and confirmed safe exposure levels have not been established, the conservative recommendation is to keep all xylitol-containing products out of reach of cats as well. When in doubt, consult your veterinarian. https://www.aspca.org/pet-care/animal-poison-control

Is peanut butter safe to give my dog? Plain peanut butter without xylitol is commonly used as a treat or to help administer medication, and many dogs enjoy it. The critical step is reading the ingredient label every single time — some brands, particularly reduced-sugar or "natural" varieties, have added xylitol as a sweetener. Never assume a product is xylitol-free based on brand familiarity alone, as formulations can change. https://www.aspca.org/pet-care/animal-poison-control

Can I use human toothpaste to brush my dog's or cat's teeth? No. Human toothpastes frequently contain xylitol and should never be used on dogs or cats. Always choose a toothpaste formulated specifically for dogs or cats, which will be free of xylitol and safe if swallowed. Your veterinarian or a knowledgeable Petco associate can help you find the right dental care products for your pet. https://www.aspca.org/pet-care/animal-poison-control

What should I do if I think my pet ate something containing xylitol? Act immediately — do not wait for symptoms to appear. Contact your veterinarian or the ASPCA Animal Poison Control Center (888-426-4435). Be ready to share your pet's weight, what was ingested, approximately how much and when. Early treatment dramatically improves outcomes, so speed matters more than anything else in a potential xylitol exposure. https://www.aspca.org/pet-care/animal-poison-control

Frequently Asked Questions

How much xylitol is toxic to dogs? Xylitol toxicity is dose-dependent, and the threshold is alarmingly low. Even a very small amount — in some cases less than one stick of sugar-free gum — can trigger dangerous hypoglycemia in dogs. Higher doses are associated with life-threatening liver failure. Because safe thresholds vary by a dog's body weight and the xylitol concentration in the specific product, there is no universally "safe" amount. If your dog has consumed any product containing xylitol, contact your veterinarian or a poison control helpline immediately rather than waiting for symptoms to appear. https://www.aspca.org/pet-care/animal-poison-control

What should I do if my dog ate something containing xylitol? Act immediately — do not wait for clinical signs such as vomiting, weakness or seizures to develop. Call your veterinarian or the ASPCA Animal Poison Control Center right away and have the product packaging on hand so you can report the ingredient list and the amount consumed. Time is critical: the faster treatment begins, the better the outcome. Do not attempt to induce vomiting or administer any home remedy without direct guidance from a veterinary professional. https://www.aspca.org/pet-care/animal-poison-control

Are all sugar-free products dangerous to dogs? Not every sugar-free product contains xylitol — some use other sweeteners such as stevia, sorbitol or sucralose — but you cannot assume a product is safe simply because it is labeled "sugar-free." Xylitol may appear on an ingredient label under names including "birch sugar" or "wood sugar," and it is present in a surprisingly wide range of products, from chewing gum and baked goods to personal care items and some medications. Always read the full ingredient list before allowing your dog anywhere near a sugar-free item, and when in doubt, keep the product out of reach entirely. https://www.aspca.org/pet-care/animal-poison-control

Is xylitol toxic to cats as well as dogs? Research on xylitol toxicity in cats is limited compared to what exists for dogs, and confirmed clinical cases are rare. This may reflect cats' famously selective eating habits or differences in feline metabolism. However, because the potential for harm cannot be ruled out, the conservative and recommended approach is to keep all xylitol-containing products away from cats just as you would from dogs. When in doubt, consult your veterinarian. https://www.aspca.org/pet-care/animal-poison-control

Which everyday products most commonly contain xylitol? Xylitol turns up in a wider range of household products than most pet parents expect. The categories most frequently associated with accidental pet exposure include sugar-free chewing gum and mints, certain peanut butters and nut spreads, baked goods made with xylitol as a sugar substitute, human toothpastes and mouthwashes, some over-the-counter liquid medications and chewable supplements, and select personal care products such as lip balms and baby wipes. Checking ingredient labels on all of these product types — especially before using peanut butter as a treat or pill pocket — is a straightforward habit that can protect your dog's life. https://www.aspca.org/pet-care/animal-poison-control

Should I use human toothpaste or mouthwash on my dog? No. Human oral care products — including toothpastes, mouthwashes, breath sprays and whitening strips — frequently contain xylitol and should never be used on dogs or cats. Always choose toothpastes and oral rinses specifically formulated for pets, which are free of xylitol and other ingredients harmful to animals. Your veterinarian or a knowledgeable Petco associate can help you select an appropriate product for your pet's dental care routine. https://www.aspca.org/pet-care/animal-poison-control
