The full answer
Veterinary sources describe ripe plum flesh, without the pit, as something dogs can eat in moderation. Too much can cause digestive upset.
The pit, stems and leaves are the concern. The ASPCA lists the plum plant as toxic to dogs because these parts contain cyanogenic glycosides, which can release cyanide. This warning is about those plant parts, not about ripe plum flesh.
A whole pit is also a physical risk: it can cause choking or get stuck in the gut.
Prunes are dried plums. They contain much more concentrated sugar and fibre than fresh plums, which makes stomach upset more likely.
Risks and Things to Know
- The pit can cause choking or a blockage in the gut.
- The pit, stems and leaves contain cyanide-forming compounds.
- Too much plum flesh may cause digestive upset.
- Prunes are concentrated in sugar and fibre.
How Much Can Dogs Eat?
Offer only a few small pieces of ripe flesh as an occasional extra.
Do not leave whole plums or fallen fruit where your dog can reach them.
Do not change a diet formulated for your dog by a veterinary nutrition professional without their advice.
How Should I Prepare It?
- Wash the plum and remove the pit, stem and any leaves.
- Cut the ripe flesh into small pieces.
- Do not offer plum jam, plum sauce or baked goods — those are different products.
