Dogs can eat the flesh of cherries in small amounts, but it is generally recommended to avoid giving them cherries altogether due to the risks involved. The pit, stems, and leaves of cherries contain cyanide, which is highly toxic and poisonous to dogs. Additionally, cherry pits can pose a choking hazard and may cause intestinal blockages if ingested. Even the flesh of cherries can sometimes cause digestive upset like vomiting or diarrhea in dogs. Therefore, if cherries are given, all the pits, stems, and leaves must be carefully removed to prevent poisoning or blockage, but it is usually safer to choose other fruits for dog treats. Avoid canned or maraschino cherries as they often contain added sugars and preservatives harmful to dogs.
