Have you ever been wondering how to get that medication into your pet, and reached for a jar of peanut butter? You’re not alone! Peanut butter – perhaps for its stickiness and for its general yumminess to dogs – is a common “tool” used among pet owners to give pet medication.

But did you know that certain brands of peanut butter contain a substance that can kill your dog? Sadly, it’s true. A sugar substitute called xylitol is being used more and more often in peanut butter, and it can spell really bad news for your dog or cat.

We’ll explore the hazards of xylitol and which products – in addition to peanut butter – to look out for in your home.

Xylitol, A Sugar Substitute

Xylitol is a five-carbon sugar alcohol commonly used as a sugar substitute in chewing gum, candies, nicotine gums, toothpastes, and baked goods. It is also available in a granulated form at grocery stores   as a sweetener.

Why is xylitol (artificial sweetener) so dangerous for dogs and cats? Ingestion of xylitol causes low blood sugar by affecting insulin release throughout the body. Low blood sugars can be seen 10-15 minutes after eating.  The low blood sugar can be compounded further into liver damage if higher levels are ingested. The liver is the main organ of metabolism.

Sugar – Free chewing gum is the most common cause in the dog—- (commonly ingested from “purse digging”)

If xylitol ingestion occurs or think it may have occurred then consult your veterinarian immediately.
