Every dog is different. Individual allergies and sensitivities are common — always introduce new foods in small amounts and watch for adverse reactions. This site is for informational purposes only and is not veterinary advice. Always consult your vet.
The Full Picture
Sugar is not toxic to dogs, but it is not beneficial and can cause health problems over time. Regular sugar consumption can lead to obesity, dental decay, diabetes, and metabolic issues. Dogs do not need added sugar in their diet — they get all the carbohydrates they need from their regular food. Foods high in sugar can also cause stomach upset and diarrhea. While a small amount of sugar won't harm your dog, it should not be a regular part of their diet. Be especially wary of sugar-free products, which may contain xylitol, a sweetener that is extremely toxic to dogs.
What You Should Know
While sugar is not outright toxic, there are important precautions to bear in mind before sharing it with your dog. Portion size matters, and certain preparations or varieties may be unsafe. If your dog has any existing health conditions, check with your vet first.
