Dark brown dog with his mouth open and eyes big reach to accept a spoon full of peanut butter

According to the ASPCA, feeding dogs peanut butter can be a nice treat or a little incentive to get the medicine to go down. It can even be used when trimming their nails or giving them a bath. In most cases, and in moderation, a little peanut butter is fine. However, pet parents do need to avoid any peanut butter that contains xylitol, an artificial sweetener that can be lethal to dogs. While xylitol is an increasingly common sugar-replacement and is gaining popularity as a sugar supplement for people with diabetes, it can be deadly for dogs.

How much is too much?

According to Preventivepet.com: The toxic dose of xylitol in dogs is even less than chocolate! For example, as little as 1.37 grams of xylitol can cause a rapid drop in a dog’s blood sugar (“hypoglycemia”) and result in staggering, disorientation, collapse, and seizures in a 30-pound dog*. If a dog of the same size ingested 6.8 grams, it could be enough to cause a debilitating and likely deadly destruction of the dog’s liver cells. Now consider that it would take about 22 times more (150 grams) dark chocolate to result in the same level of severe toxicity.

What are the dangers of Xylitol in pets?

While xylitol is a good sugar substitute for humans, especially people with diabetes, giving dogs peanut butter can be deadly. If consumed it can cause:

  • a rapid drop in blood sugar
  • diarrhea
  • seizures
  • liver failure
  • death

Signs & Symptoms that your dog may need emergent care:

  • pale gums

If your dog consumes a product containing xylitol:
