Yes, and this is the worst form of chocolate in most kitchens. Cocoa powder is chocolate with the fat and sugar taken out, which leaves theobromine concentrated, so gram for gram it carries far more than a milk chocolate bar. A spilled tub is a serious exposure in any size of dog.

Why Cocoa Powder is dangerous
Theobromine is the compound that makes chocolate dangerous to dogs, and its concentration tracks cocoa solids. Cocoa powder is essentially nothing but cocoa solids: the cocoa butter has been pressed out and no milk or sugar has been added back, which is precisely what makes it the densest common source. The ASPCA lists chocolate among foods to avoid, and Merck describes methylxanthine toxicosis running from vomiting and restlessness through a racing heart and tremors to seizures in significant exposures. Two practical features make cocoa powder worse than its position in the cupboard suggests: it is sold in large tubs rather than portions, and it is light and loose, so a dog that gets into one can ingest a great deal quickly and coat itself in the rest, adding more by grooming.

Signs to watch for
Vomiting, diarrhea, marked thirst, restlessness and pacing, panting; progressing to a fast or irregular heart rate, tremors, and in severe exposures seizures. Signs can begin within a couple of hours and last a long time

Check the exact item or ingredient before assuming two similar exposures carry the same risk.
What to do next
Weigh what is missing if you can, or note the tub size and roughly what fraction is gone, since this is one exposure where the arithmetic genuinely guides treatment. Check whether your dog is also wearing some of it, and stop them grooming it off. Have three numbers ready when you call: your dog's weight, how much was eaten, and what kind of chocolate it was, because the dose depends on all three and not on the brand.

Chocolate with everything else removed
The cupboard hierarchy that owners carry in their heads, dark bad and milk less bad, stops at the baking shelf. Cocoa powder sits above all of it.
1. Concentration is the whole difference
Making cocoa powder means pressing the fat out of cocoa solids and adding nothing back. Theobromine tracks those solids, so the resulting powder carries substantially more per gram than a bar in which sugar, milk, and cocoa butter make up most of the weight. The intuition that a spoonful is less than a bar is exactly backwards. How chocolate poisoning works in dogs →
2. Tub size and dust make it worse
Chocolate usually arrives in portions; cocoa powder arrives in a container holding many portions' worth, and it is loose enough to spill widely. A dog that noses into a tipped tub gets a large ingestion plus a coated muzzle and paws, and grooming adds more over the following hour. Preventing further grooming is a genuinely useful thing to do while you are on the phone. The weight-by-type chocolate guide →
3. Cacao powder and cocoa mix are not the same product
Raw cacao powder is at least as concentrated as cocoa powder and sometimes more so. Sweetened drinking chocolate mix is mostly sugar and milk solids and carries much less, though a sugar-free version raises a xylitol question instead. Read the label rather than the shelf position, and say which one it was when you call. Hot chocolate and drinking mixes →
FAQ
No amount is safe, and with chocolate the numbers genuinely guide treatment, so they are worth gathering carefully. Theobromine content varies between brands and between natural and Dutch-processed powders, which is why guidance uses weight of product against weight of dog rather than spoon counts. Even a couple of tablespoons is a meaningful exposure for a small dog.
A dusting licked off a worktop by a large dog may end up being monitored, but that is a decision for a phone call rather than for you alone, because the concentration makes small amounts count for more here than with a candy bar.
Call now for any real quantity, for a spilled or chewed tub, and for any amount at all in a small dog or puppy. Call immediately for restlessness or pacing, panting, a racing or irregular heartbeat, vomiting, muscle tremors, or a seizure. Mention that it was cocoa powder rather than chocolate, since the concentration changes the calculation.
There is no safe amount, and because cocoa powder is the most concentrated common form, even a couple of tablespoons is meaningful for a small dog. Theobromine content varies by brand and by whether it is natural or Dutch-processed, so the useful approach is weight of powder against your dog's weight with a vet or poison-control line, not a spoon count.
Gram for gram, considerably worse. A bar is mostly sugar, milk, and cocoa butter, while cocoa powder is close to pure cocoa solids, which is where theobromine lives. That is why a spilled tub can be a bigger exposure than a whole bar.
Yes, because dogs groom. What is on the coat will end up swallowed over the next hour or so, adding to the dose. Stop your dog licking it off, wipe or wash it away, and mention it on the phone so the estimate accounts for it.
