Can Dogs Eat Plums? In Moderation

Why it’s fine in small amounts

The soft flesh of a ripe plum is safe for most healthy dogs as an occasional treat. PetMD describes plums as mostly water, sugar and fiber with some vitamins A and C and potassium, and says too much can cause vomiting or diarrhea and add weight.

The hazard is the pit. PetMD says the pit and stem are toxic to dogs and can cause choking or an intestinal blockage. The ASPCA lists the plum plant as toxic to dogs because its stems, leaves and seeds contain cyanogenic glycosides, which release cyanide, and it adds that the plant is particularly toxic while wilting. The ASPCA's listed signs include brick-red mucous membranes (such as the gums), dilated pupils, difficulty breathing, panting and shock.

Prunes, which are dried plums, are concentrated in sugar and not a good treat.

Benefits

Provides fiber, vitamins A and C and potassium
A few small bites may help digestion, according to PetMD

Risks

The pit and stem can cause choking or an intestinal blockage
Pits, stems and leaves contain cyanide-forming compounds
Too much can cause vomiting or diarrhea because of sugar and fiber
Prunes are high in sugar and can cause gas and digestive upset

How to serve it safely

Wash the plum, remove the pit and stem, and cut the flesh into small pieces. PetMD's guide for healthy adult dogs runs from 1 or 2 small pieces for dogs up to 20 lb (9 kg) up to 10 small pieces, no more than 1/4 cup (60 ml), for dogs over 90 lb (41 kg). Treats should stay under about 10% of daily calories.

Skip prunes and dried plum snacks, and never let your dog play with plum pits. Blueberries and watermelon are easier, pit-free options.

If your dog already ate it

If your dog swallowed a plum pit, call your vet right away, even if your dog seems fine. PetMD says to contact your vet immediately if a pit is swallowed, and pits can lodge in the throat or gut.

Go to an emergency clinic for gagging, repeated vomiting, belly pain, loss of appetite or constipation, which can signal a blockage, and for trouble breathing, panting, collapse or brick-red gums, which can signal cyanide poisoning. You can also call ASPCA Animal Poison Control at (888) 426-4435 or Pet Poison Helpline at (855) 764-7661 (US; fees may apply). Outside the US, call your local emergency vet. Do not make your dog vomit at home.

A few extra pieces of plum flesh usually cause only a loose stool.
