Yes, Indian hemp is severely toxic to dogs. Its cardiac glycosides, concentrated in the roots and milky sap, can push the heart into dangerous rhythms.

Also known as: Dogbane, Amy Root, Hemp Dogbane, Rheumatism Root · Apocynum cannabinum

What makes it toxic

Digoxin-like cardiac glycosides throughout the plant, with the root and white latex sap carrying the highest load. They disrupt heart muscle cell signaling and harshly irritate the digestive tract.

Warning signs to watch for

Vomiting, diarrhea, drooling, dilated pupils and lethargy within hours, then a slow or irregular pulse, weakness and potentially collapse or seizures.

What to do if your dog eats it

Emergency vet care for any significant ingestion. Tell the vet it was Indian hemp (dogbane) — cardiac glycoside exposure calls for ECG monitoring, and early treatment changes outcomes.

Common questions

Is it called dogbane because it kills dogs?

The name reflects its well-known toxicity to dogs and other animals. Livestock deaths are documented, and dogs chewing the roots of this common roadside plant are genuinely at risk.

What if my dog only chewed a stem?

A stem chewed briefly causes less exposure than root digging, but the sap alone can be swallowed while chewing. Rinse the mouth and call your vet to decide on monitoring.
