Dogs can eat ripe mulberries in moderation as they are not toxic to dogs. Mulberries offer several health benefits including antioxidants, dietary fiber, iron, vitamins for bone and brain health, and cancer-fighting anthocyanins. However, feeding too many mulberries can cause stomach upset or diarrhea in some dogs. It is important to avoid feeding unripe mulberries because they contain hallucinogenic properties that may cause adverse effects. Start with a small amount of mulberries to see how a dog reacts and always consult a veterinarian before introducing new foods. Mulberry leaves are also non-toxic but should be given sparingly to avoid digestive issues. Overall, ripe mulberries can be a healthy occasional treat for dogs but should be fed in small quantities and with caution.
