Can Peanut Butter Kill Your Dog?

If you haven't heard this one yet, listen up!

Peanut butter can make a delicious treat and dogs love it. I myself give it to our dogs sometimes. Until recently it was a perfectly safe thing to do.

New peanut butter products are now on the market that contain xylitol!

The list of peanut and nut butters containing xylitol seems to be rising. Xylitol is very toxic to 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." ~Preventive Vet

Beware and read labels carefully.

  1. I've started looking at more ingredients panels since the news of peanut butter. We don't have any brands that carry xylitol in our stores, but it's still important to look for, because some don't include it on their labels and some have made the change to add it.

    1. They put this stuff into almost everything these days. One has to check and double-check everything. Even medications and supplements - everything.

  2. Isn't peanut butter with any sweetener in it bad for dogs? I am kind of surprised that it took the addition of an extremely toxic sweetener for the dangers of unnecessary additions to peanut butter to be brought up. Dogs also shouldn't eat sugar or high fruitcose corn syrup and those ingredients (and then some) have been added to major peanut butter brands for decades. Maybe this deadlier to dogs addition will finally make people question why peanut butter needs all these extras. The organic peanut butter I have been buying for 20 years has one ingredient- peanuts. And it's delicious! (My dogs, however, are not peanut butter eaters.)

    1. Hi Bethany,

      actually, it isn't. Unless the dog is allergic to peanuts, unless there is a ton of sugar or salt, peanuts or peanut butter are a delicious, nutritious treat. You're right, organic peanut butter with nothing but peanuts in it is best.
