Artificial Sweeteners Dangerous For Dogs

When discussing dangerous artificial sweeteners for dogs, the most common one we hear about is xylitol. While this certainly is the most toxic synthetic sugar, it does not mean that it’s the only artificial sweetener that can cause our dogs harm.

So what other artificial sweeteners should we be aware of?

In this article we will introduce you to a list of artificial sweeteners that are in common food items, and help you understand which ones are dangerous for your furry friend.

What Are Artificial Sweeteners?

Artificial sweeteners are all the rage in food these days. Since these synthetic sweeteners often have the same sweet flavor without the high caloric index, they are extremely popular in lower calorie food. You can also use much less of an artificial sweetener than a natural sugar additive, as they tend to be even sweeter than normal sugars.

Some of the most common items that contain artificial sweeteners include:

  • sodas
  • powdered drink mixes
  • candy
  • jelly
  • canned food
  • baked items
  • and even dental care products.

With being in so many food items that we keep in our home, these artificial sweeteners can pose a threat to our canine companions.

Though we never recommend offering your dog a diet that contains any artificial sweeteners, we understand that accidents happen. Sometimes our dogs get their paws on items around our home that are not intended for them. Its extremely important to know which ingredients can harm your dog.

Different Types of Artificial Sweeteners

Now that we have introduced you to artificial sweeteners and the low calorie flavor they provide, let’s dive into some of the most common artificial sweeteners on the market. While some of these synthetic sugars may sound familiar, there are others that you may have never noticed before.

Let’s discuss each synthetic sweetener in detail, and help you understand how each ingredient can impact your beloved pup.


As you may already know, xylitol is an extremely toxic artificial sweetener for dogs. Even the smallest amount of xylitol can cause devastating symptoms in our canine companions, even being fatal in some cases. Xylitol causes a sudden and drastic drop in blood sugar in dogs when it’s consumed. This can cause an array of serious symptoms.

Dogs that consume xylitol can experience weakness, difficulty standing, shaking, vomiting, collapse, seizures, and even death. Severe hypoglycemia (low blood sugar) can have a devastating impact on the dog affected and can even cause permanent liver damage. No matter how small of an amount that your dog gets their paws on, xylitol is extremely dangerous.

If your dog ever consumes an item with xylitol, it’s important to seek veterinary assistance immediately. The sooner you offer your dog medical assistance, the better their chance of a full recovery. Just be sure to bring the ingredient details with you of the item they consumed, as this helps your vet find the best treatment option.

Some of the common items that contain xylitol include:

  • sugar free gum
