Purslane is mildly toxic to dogs. Eating the weed causes vomiting and diarrhea from soluble oxalates; serious effects need an unusually large meal.

Also known as: Verdolaga, Pigweed, Little Hogweed, Portulaca oleracea · Portulaca oleracea

What makes it toxic

Soluble calcium oxalates concentrated in leaves and stems, which irritate the gut and, in large doses, bind calcium and stress the kidneys.

Warning signs to watch for

Vomiting, diarrhea, drooling and mild lethargy within hours; heavy intake could add tremors from calcium binding, though that is uncommon.

What to do if your dog eats it

Offer water, remove access and watch. Call your vet if vomiting continues, the dog seems painful, or a big quantity was eaten.

Common questions

My dog eats purslane straight from the sidewalk cracks — stop it?

Yes. Besides oxalates, sidewalk plants collect herbicides, exhaust residue and dog urine. A single graze rarely harms, but the habit is not one to allow.

Is cooked purslane in my lunch safe if my dog begs?

Cooking reduces oxalates somewhat, but seasoned dishes bring oil, salt and onion. Do not share — the plate is riskier than the weed.
