In general, dogs should not eat sugar. Dogs can consume foods with naturally occurring sugars, like [fruits](https://www.masterclass.com/articles/what-fruits-can-dogs-eat) and vegetables, but dog owners should avoid feeding their pets food products containing added sugar. Semi-regular sugar consumption can cause weight gain and impact various organs and metabolic processes.

Dogs can consume foods with natural sugars, such as [watermelon](https://www.masterclass.com/articles/is-watermelon-good-for-dogs) and [blueberries](https://www.masterclass.com/articles/are-blueberries-good-for-dogs). The amount of sugar in fruit is generally moderate, and fruits contain water and fiber, which help slow the body’s absorption of fruit sugars like fructose. In addition, as with humans, dogs benefit from the various micronutrients found in fruits and vegetables.

Like humans, dogs need carbohydrates to support the healthy functioning of their bodies. Their bodies’ metabolic processes convert complex carbohydrates—found in many kinds of dog food and dog treats—into a necessary form of sugar called glucose. However, too many carbs and products with added sugar will quickly unbalance their organ systems, leading to various health problems.

Humans can tolerate moderate amounts of sugar, but dogs are more sensitive. Consuming large amounts of sugar can cause a host of health issues for dogs, including:

1. __Stomach upset__: Excessive amounts of sugar are hard on your furry friend’s digestive system, and the most likely immediate symptoms will be in the form of an upset stomach. Your dog may experience indigestion, bloating, vomiting, and diarrhea.  
2. __Metabolic issues__: Dogs can also develop longer-term health problems if regularly fed sugar. These include weight gain, obesity, high blood sugar, diabetes, and heart disease. Sugar also contributes to systemic inflammation, including inflammation of the pancreas, known as pancreatitis, which can be life-threatening to dogs.
3. __Tooth decay__: Too much sugar can lead to tooth decay and gum disease. Harmful mouth bacteria can thrive on sugar, producing acids that eat away at tooth enamel and cause inflammation of the gums.

Many sugar-free products use artificial sweeteners that can be harmful to dogs. For example, peanut butter often includes xylitol, which can cause liver failure and seizures. Even low-sugar dark [chocolate](https://www.masterclass.com/articles/can-dogs-eat-chocolate) contains theobromine, a prodrug of caffeine toxic to dogs. Always avoid feeding your dog food that contains artificial sweeteners.

Certain human foods can cause adverse reactions in canines, so always consult your veterinarian to determine whether it is safe to add these foods to your pet’s diet. This article is for educational and informational purposes and is not a substitute for medical or dietary advice.
