Yes, plum tree is toxic to dogs. Chewing pits, stems or wilted leaves releases cyanide-forming compounds, and swallowed pits can also obstruct the gut.

Also known as: Prunus Domestica, European Plum · Prunus domestica

What makes it toxic

Amygdalin-type cyanogenic glycosides in pits, stems and wilted foliage, converted to hydrogen cyanide during digestion; pits add a physical obstruction risk.

Warning signs to watch for

Drooling, vomiting, rapid breathing, bright red gums, weakness and tremors within hours of chewing leaves or cracked pits; obstruction causes persistent vomiting later.

What to do if your dog eats it

For a chewed pit or leaf eating, call your vet or a poison hotline immediately. Intact swallowed pits need advice about obstruction; labored breathing is an ER sign.

Common questions

Is it safe for my dog to eat plums that fall in the yard?

The flesh is safe in moderation, but dogs often crunch the whole fruit and swallow pits. Pick up fallen plums and limit the snacking.

Are plum leaves dangerous when my dog grazes under the tree?

Fresh leaves are less potent than wilted ones, but all Prunus foliage carries the glycosides. Prevent regular grazing.
