If you indulge your beloved dog with occasional peanut butter, please be aware of an increasingly common artificial sweetener called Xylitol.
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."

Please, as always, make sure to read the ingredients of your products and if you have something containing Xylitol, keep it far away from your dog.
