However, with the introduction of a unique line of peanut and other nut butters onto the market — Nuts ’N More — the answer to the question of whether or not it’s safe to give, even a small quantity of, peanut butter to your dogs is no longer a straightforward one. Why? Because of the sweetener that’s been used to replace the sugar in this line of peanut and other nut butters. That sugar substitute is called xylitol.
UPDATE (June 14, 2015): We have learned of a second brand of peanut butters that also contain xylitol — Krush Nutrition. We will be reaching out to them to discuss adding awareness to their product packaging. They currently provide a “Xylitol and Dogs” warning in their FAQ section of their website, as well as on their product pages.
Is Xylitol Safe For Dogs?Xylitol is a sweetener that's gaining in popularity because of its dental benefits for people as well as its suitability as a sugar substitute for people with diabetes. Because of its ability to help prevent cavities and tooth decay and its low glycemic index, xylitol is proving to have some good dental and other health benefits for people. Unfortunately, while xylitol appears to be perfectly safe for people, it is extremely dangerous for dogs — even in small quantities.
- Ingestion of as little as 0.1 gram (g) of xylitol per kilogram (kg) of body weight (0.1 g/kg) can cause a rapid and dangerous drop in a dog’s blood sugar (a condition called “hypoglycemia”). Hypoglycemia can show as staggering, appearing disoriented, collapse, weakness, and seizures.
- Just slightly more than that, approx. 0.5 g/kg xylitol ingestion, can lead to debilitating, and sadly often deadly, destruction of a dog’s liver cells.
These quantities, or toxic doses, are based on the data that the animal-specific poison control hotlines have collected from reported cases*. To highlight that these are reported cases is important, because not every case of toxicity makes it to the vet, and not everyone that does go to the vet is called into the animal poison control hotlines. So the actual toxic doses could be even lower, and dogs with certain pre-existing medical conditions (such as diabetes, hepatitis, and others) are likely to be even more sensitive to the toxic effects of xylitol.
Make Sure To Read Ingredient Labels
In the mean time, please learn more about the danger xylitol poses to dogs and the range of products xylitol is commonly found in. And since awareness is truly crucial to helping people avoid xylitol toxicity in dogs, please share what you’ve learned here with your dog-owning and dog-loving friends and family.
