Yes, though the mechanism is irritation rather than anything that reaches the heart. Pokeweed causes vomiting, diarrhea, and abdominal pain, with the root by far the most toxic part and the glossy purple berries the part a dog is most likely to actually eat.

Why Pokeweed is dangerous
Pokeweed contains saponins and related compounds that irritate the digestive tract, producing vomiting, diarrhea, and abdominal discomfort, and the ASPCA lists Phytolacca as toxic to dogs. Concentration is not uniform across the plant: the thick taproot holds the most, the stems and leaves less, and the berries less again, which matters because the berries are what a dog is realistically going to eat. That combination, most toxic part hardest to reach and least toxic part most attractive, is why most exposures produce an unpleasant day rather than a crisis. Large ingestions, and particularly a dog that dug up and chewed the root, are a different matter, and can bring more serious signs including weakness and low blood pressure.

Signs to watch for
Drooling, vomiting, diarrhea, sometimes bloody, abdominal pain, reduced appetite; with a large ingestion or root material, weakness, tremors, and signs of low blood pressure or collapse

Check the exact item or ingredient before assuming two similar exposures carry the same risk.
What to do next
Establish which part was eaten, since root and berries are very different exposures, and photograph the plant to confirm identification, because pokeweed is regularly confused with elderberry. Note the amount and the time, and watch for dehydration if vomiting and diarrhea persist.

An irritant, not a heart poison
Pokeweed has an alarming reputation and a comparatively mundane mechanism, and knowing which part your dog reached is what separates an unpleasant evening from a veterinary visit.
1. The toxin is concentrated in the root
Pokeweed's compounds are distributed unevenly: the thick taproot is by far the most potent part, with stems and leaves lower and berries lower still. In practice that is fortunate, since the berries are the part hanging at dog height and the root is underground. A digging dog, or one loose in a garden being cleared, undoes that protection.

2. Berries are the likely exposure and the milder one
Glossy dark purple berries on a red stem are attractive to dogs and to children, and a few eaten by a healthy adult dog will usually produce vomiting and loose stool rather than anything worse. The realistic risk in that scenario is dehydration if the vomiting and diarrhea go on, which is what to watch for rather than dramatic signs. Other berry-bearing garden plants →
3. Identify it before you treat it as pokeweed
Pokeweed is commonly confused with elderberry, and the two have quite different profiles. The giveaways are the smooth magenta stem, the berries hanging in drooping clusters, and the sheer size of an established plant. Photograph it, because that photograph is more useful to a vet than any description of the berries. Planning a dog-safe garden →
FAQ
No canine threshold is published. Judge the exposure by which part was eaten and how much: a few berries is a stomach-upset expectation, whereas chewed root is a call regardless of quantity. Season matters too, since the plant dies back to that root over winter and a digging dog can reach it when there is nothing visible above ground.
A dog that ate a few berries and is otherwise well can often be monitored at home after a phone call, with water available and a bland meal if the stomach is unsettled. Expect vomiting or loose stool; keep watching rather than assuming it is finished.
Call for any chewed root, a large quantity of any part, a puppy or small dog, or an exposure you cannot quantify. Call immediately for repeated vomiting that will not stop, bloody diarrhea, weakness or collapse, or a dog that seems distant or unresponsive. Dehydration from persistent vomiting and diarrhea is the most common reason these cases need treatment.
Most likely vomiting, diarrhea, and a poor appetite rather than anything more serious, since the berries are the least toxic part. Keep water available, offer a bland meal if the stomach is unsettled, and call your vet if the vomiting or diarrhea persists, becomes bloody, or your dog is small.
The root, by a considerable margin, followed by the stems and leaves, with the berries the least concentrated. That is why a dog that dug up and chewed a root warrants a call regardless of the amount, while a few berries usually means an upset stomach.
Pokeweed has a smooth magenta or reddish stem, large simple leaves, and dark purple berries in drooping clusters, and an established plant can be very large. Elderberry is a woody shrub with compound leaves and berries in flat-topped clusters. Photograph the plant so a vet can confirm rather than relying on the berry color alone.
