Plums are dangerous for dogs. The main concern is the pit, which contains cyanide and can also pose a choking hazard or cause gastrointestinal obstruction. While the fruit flesh is not highly toxic, it can cause digestive upset.
How It Affects dogs
Amygdalin in the plum pit is metabolized into hydrogen cyanide, which inhibits cytochrome c oxidase, disrupting cellular respiration and oxygen utilization.
Toxic Compound
Cyanide (specifically amygdalin)
