While oranges can provide vitamin C, there are alternative sources that may be safer for your French Bulldog. Many commercial dog foods are formulated to meet a dog's nutritional needs, including vitamin C. Additionally, other fruits such as strawberries, blueberries, and kiwi are lower in acidity and natural sugars compared to oranges and can be suitable sources of vitamin C. Always consult with your veterinarian to determine the best dietary options for your individual Frenchie, as they can provide guidance tailored to your dog's specific needs
