Pumpkin seeds are not toxic, but the shells can obstruct the gut and salted seeds can push a dog into salt toxicosis. Give shelled, unsalted, lightly roasted and ground seeds in tiny amounts, and never use them in place of a real dewormer.

More about this food
Pumpkin seeds are not poisonous to dogs. Three other things make them a caution: the shell, the salt, and the fat.
Start with the shell. AKC's seed guidance is blunt about hulls, which can get stuck in the digestive tract and cause a blockage or obstruction. Pepita shells look flimsy but are tough and pointed, and a small dog or a gulper is exactly the wrong customer for them. Hand over shelled pepitas, never the salted in-shell seeds you eat at a ballgame.
Then the salt. AKC notes that the salt on packaged seeds can cause salt toxicosis, with muscle tremors, weakness and gastroenteritis. Merck puts clinical signs in dogs at 2-3 g/kg of sodium chloride, with roughly 4 g/kg lethal. That makes a spilled bag of salted roasted pepitas a real call to your vet, not a shrug. Anything candied, honey-roasted, or mixed into a trail mix with raisins and chocolate is off the table entirely, since raisins alone cause acute kidney injury.
Third, fat. Seeds are calorie-dense, and AKC's own warning about nuts and seeds is that the fat load leads to obesity and pancreatic problems. Any dog with a history of pancreatitis or a sensitive gut should skip them. Their unsaturated oils also go rancid, so throw out seeds that smell sharp or stale.
One myth needs naming. Ground pumpkin seed is widely promoted as a natural dewormer on the strength of cucurbitin, but there is no clinical evidence it deworms dogs. Skipping a prescription dewormer or monthly heartworm preventive because you are feeding pepitas is far more dangerous than the seeds themselves. Deworming is a veterinary prescription, not a kitchen remedy.
If you do give them: shelled, unsalted, dry-roasted with no oil, ground, and sprinkled on food. A pinch a day for a small dog, up to about a teaspoon for a large one, inside the usual 10% treat budget. If your dog ate a pile of in-shell or salted seeds, leave fresh water freely available and call your veterinarian, or the ASPCA Animal Poison Control Center at (888) 426-4435. Repeated vomiting, belly pain or no stool means possible obstruction. Do not induce vomiting at home.
Frequently asked questions
My dog ate salted pumpkin seeds from the counter. Is that serious?
It depends on how many and how big your dog is; salt toxicosis signs start around 2-3 g/kg of sodium chloride. Leave water freely available, do not restrict it, and call your vet or the APCC at (888) 426-4435 with the bag and your dog's weight.
Do pumpkin seeds really work as a natural dewormer?
There is no clinical evidence that they deworm dogs, and relying on them means skipping proven parasite control. Use the dewormer and heartworm preventive your veterinarian prescribes instead.
Do I have to shell them?
Yes. Hulls are the part that lodges in the digestive tract and cause blockages, and they add nothing nutritionally. Buy shelled pepitas, roast them dry with no salt or oil, and grind them before serving.
