Did You Know Xylitol Goes by Another Name? Birch Sugar Can Be Deadly for Dogs

You’ve probably heard that xylitol is toxic to dogs, but did you know it’s now being disguised under other names like birch sugar and even birch sap? These terms might sound natural, even healthy, but to your dog, they can be extremely dangerous.

At Cream Puff Labradoodles, our priority is your puppy’s health and safety. That’s why we’re spreading the word about this hidden hazard. so you can protect your pup from a very preventable risk.

What Is Xylitol (a.k.a. Birch Sugar or Birch Sap Derivative)?

Xylitol is a sugar alcohol used as a sweetener in many “sugar-free” or “keto-friendly” products for humans. It’s safe for people, but highly toxic to dogs.

It’s often made from birch sap or corn, which is why you might now see xylitol labeled as:

• Birch sugar

• Wood sugar

• Or even described in vague terms like “naturally derived from birch sap”

This natural-sounding language can easily confuse dog parents who are trying to make healthy choices, especially when shopping for products like peanut butter, which most of our furry friends love.

Common Products That May Contain Xylitol or Birch Sugar

Always read labels closely, especially on:

• Sugar-free gum and mints

• Peanut butter (even the "healthy" kind)

• Baked goods

• Oral care products like toothpaste and mouthwash

• Medications and supplements

• Keto, diabetic, or low-carb snacks

If you see xylitol, birch sugar, or anything referencing birch sap, do not share it with your dog and keep it stored safely out of reach.

Why Is Xylitol So Dangerous to Dogs?

In dogs, xylitol causes a sudden release of insulin, which can lead to:

• Severe hypoglycemia (low blood sugar)

• Vomiting, weakness, and lethargy

• Loss of coordination

• Seizures

• Liver failure or death, especially in larger doses

Some dogs have had fatal reactions to as little as one or two pieces of xylitol-sweetened gum. The danger is real and immediate.

Don’t Be Fooled by “Natural” Names Like Birch Sugar or Birch Sap

Here’s the tricky part:Labels that list birch sugar or claim the sweetener is "derived from birch sap" are still talking about xylitol. This marketing tactic can give dog parents a false sense of safety.

But no matter what name it goes by, xylitol is xylitol, and it’s just as toxic whether it comes from corn, birch trees, or anything else.

How to Protect Your Dog

1. Read every label. Especially on anything labeled "sugar-free," "keto," or "low-carb."

2. Watch out for these terms:

3. Xylitol

4. Birch sugar

5. Derived from birch sap

6. Wood sugar

7. Keep risky products out of reach, just like you would with chocolate or grapes.

8. Stick to dog-approved peanut butters and treats. You can check out our puppy supply list for treat recommendations, and we’ve compiled a list of xylitol-free, dog-safe peanut butters below.

9. Educate everyone in your household about xylitol dangers, including kids and guests.

What to Do If Your Dog Ingests Xylitol or Birch Sugar

If you think your dog ate something containing xylitol, birch sugar, or anything made with birch sap:

• Call your vet immediately

• Or contact the ASPCA Animal Poison Control Center: 888-426-4435

• Be prepared to share the product name, ingredients, and an estimate of how much was eaten

Don’t wait. Symptoms can begin within 10–60 minutes of ingestion, and early intervention can save your pup’s life.
