Can dogs eat Plums?
In small amounts, with care
In moderation - plum flesh is harmless, but the stone contains cyanide compounds and is exactly the right size to block a dog's gut. Most owners decide it is not worth the preparation.

What happens
The flesh of a ripe plum is not toxic and a small piece will not hurt a dog. Everything else about a plum is a problem. The stone contains amygdalin, which releases cyanide when it is crushed or chewed, so a dog that cracks one open is at genuine risk. Even swallowed whole the stone is a hard, round object of precisely the wrong dimensions, and obstruction is the more common emergency of the two. The leaves, stems and wilting foliage of plum trees carry the same cyanogenic compounds, which matters if you have one in the garden and a dog that chews branches. Plums are also high in sugar and in sorbitol, which is a natural laxative, so even the safe part causes loose stools in quantity.
How much is safe?
A small piece or two of de-stoned flesh for a large dog, rarely. Given the effort and the risk, a slice of apple or a few blueberries does the same job with none of it.
How to prepare it
Fresh ripe fruit only, washed, with the stone removed completely and the flesh chopped. Never tinned plums in syrup, never prunes, and keep fallen fruit picked up if you have a plum tree.
Symptoms to watch for
Loose stools or diarrhoea from the sugar and sorbitol. Cyanide poisoning is rare but serious - bright red gums, dilated pupils, laboured breathing, wobbliness or collapse. Obstruction looks different: repeated vomiting, straining without producing, a tender belly and refusing food.
When to call the vet
Immediately if your dog has chewed or crushed a stone, or shows breathing difficulty or bright red gums. Also call if a stone was swallowed whole and vomiting or straining follows.

Common questions
What if my dog swallowed a plum stone?
Ring your vet. Swallowed whole it is mainly an obstruction risk, particularly in a small dog - watch for repeated vomiting, straining, a tender belly or refusing food. If your dog crushed and chewed it, that is a cyanide concern and needs attention straight away.
Can dogs eat prunes?
Better not. A prune is a dried plum, so the sugar is concentrated and the sorbitol content makes diarrhoea very likely. They are not toxic like raisins, but there is no reason to give them.
Are plum trees dangerous for dogs?
The leaves, stems and wilting foliage contain the same cyanogenic compounds as the stone, so a dog that chews branches is at risk. Pick up fallen fruit and discourage chewing if you have one in the garden.
