Can Dogs Eat Sugar?

Verdict: CAUTION — sugar isn't toxic, but dogs should not eat it.

A little sugar here and there won't poison your dog, but it's one of the unhealthiest things you can regularly feed them. Dogs have no nutritional need for added sugar — the only sugar they should get is the natural kind in dog-safe fruits and vegetables.

Why sugar is bad for dogs

• Stomach upset: gas, bloating, vomiting, diarrhea (sometimes explosive).
• Obesity: sugar is empty calories that add up fast.
• Diabetes risk: repeated sugar can contribute to metabolic problems.
• Dental problems: cavities and gum disease.
• Pancreas stress: large amounts can harm the pancreas.

The real danger: xylitol

Sugar substitutes are worse than sugar. Xylitol — common in gum, candy, sugar-free treats and toothpaste — is extremely toxic to dogs. Even a small amount causes a rapid drop in blood sugar, seizures and liver failure. If your dog eats anything with xylitol, call your vet immediately.

What to do if your dog ate sugar

• A little sugar or a cookie: watch for stomach upset.
• A lot of sugar, candy, or anything with xylitol: call your vet right away.
