Dogs can eat satsumas safely, but only in small amounts. Satsumas, a juicy variety of mandarin oranges, are not toxic to dogs. However, due to their high natural sugar content and acidity, overfeeding satsumas can lead to gastrointestinal upset such as diarrhea or vomiting. It's important to peel the satsumas and remove any seeds before giving them to dogs, as the peel and seeds can be harmful or cause choking. Additionally, diabetic or overweight dogs should avoid satsumas because of the sugar content. Overall, satsumas can be a safe occasional treat if given in moderation and with proper preparation. Dogs with sensitive stomachs or certain health conditions should avoid them or be given very small amounts initially to test tolerance.
