While the fruits themselves are not cause for concern, the pits inside them, certainly are. These pits contain the compound amygdalin, which breaks down into hydrogen cyanide when digested, and they are toxic to your dogs. This can cause vomiting, decreased appetite, constipation, and decreased pooping. The pit can also cause intestinal blockages, which is already serious in itself. The seeds of persimmons are also known to cause inflammation in the intestines.
