Birch Sugar: The Dangerous New Name for Xylitol

PSA for every dog parent and label reader:

They’ve started calling xylitol by a new, “natural”-sounding name — birch sugar.

It sounds like something harmless, maybe even healthy. Like it came straight from a tree and belongs in your granola.

But here’s the truth: Birch sugar = xylitol. Same thing. Same danger.

And that danger? It’s serious.

Why Xylitol (aka Birch Sugar) Is So Dangerous for Dogs

Xylitol is a sugar alcohol that’s used as a sweetener in many “sugar-free” products made for humans. It doesn’t affect people much — but for dogs, it’s extremely toxic.

Even small amounts can trigger a dangerous drop in blood sugar (hypoglycemia) and lead to liver failure. We’re talking micro-doses — a single piece of sugar-free gum or one muffin sweetened with xylitol can kill a dog.

Symptoms can set in fast — vomiting, weakness, staggering, seizures. Immediate emergency care is critical.

Common Products That May Contain Xylitol or Birch Sugar

If you spot any of the following in your kitchen or bathroom, double-check the ingredients:

• Sugar-free gum and mints
• Sugar-free baked goods
• Peanut butters or nut butters labeled as keto or diabetic-friendly
• “Healthy” protein bars
• Oral care products like toothpaste and mouthwash
• Flavored vitamins or medications
• Ice cream or yogurt alternatives

Some companies have started using the term birch sugar instead of xylitol to sound more appealing to health-conscious consumers — but the risk to dogs is still the same.

What to Look for on the Label

Next time you’re checking labels (for your pup’s treats or your own pantry), keep an eye out for:

❌ Xylitol
❌ Birch sugar
❌ Sugar alcohols (and other terms that may mask xylitol)

And remember: human food and treats — especially anything labeled "sugar-free" — should never be shared with your dog unless you’re 100% certain of the ingredients.

What to Do if You Suspect Xylitol Poisoning

If your dog eats anything that might contain xylitol or birch sugar:

1. Call your vet immediately

2. Contact an emergency animal poison control line:

   • ASPCA Poison Control: 888-426-4435

   • Pet Poison Helpline: 855-764-7661

Every second counts.
