6 min read · Updated September 2026

UNSAFE. Hershey's milk and dark chocolate both contain theobromine, a compound toxic to dogs.

← US Food Guides

No safe servingReviewed

No, dogs cannot safely eat Hershey's chocolate in any form. Milk chocolate, dark chocolate, and Hershey's Kisses all contain theobromine, with dark chocolate and Hershey's Special Dark containing significantly more per ounce than milk chocolate. Toxicity depends on both the amount eaten and your dog's body weight, small dogs are at risk from far smaller amounts than large dogs.

Hershey's in the American Pantry

Hershey's products span the widest range of any chocolate brand in US homes, from Kisses in a candy dish to baking bars in the cupboard to syrup in the fridge door. Baking chocolate is the version owners think about least and the one that causes the most severe cases, because it is the most concentrated form in the house.

What Makes Hershey's Chocolate Dangerous for Dogs

Chocolate offers no nutritional benefit to dogs; the compounds below explain the danger.

CompoundAmountEffect on Dogs
Theobromine (dark chocolate)HighToxic; dogs metabolize it very slowly
Theobromine (milk chocolate)ModerateToxic, but less concentrated than dark chocolate
Sugar and milk fatHighNo benefit; risk of GI upset

Risks of Hershey's Chocolate for Dogs, and When to Worry

RiskLevelMost at risk
Theobromine toxicosis, dark/baking chocolateHIGHAll dogs, especially small breeds
Theobromine toxicosis, milk chocolateMEDIUM-HIGHAll dogs, larger amounts needed than dark chocolate
Wrapper or foil ingestion (Kisses, bars)MEDIUMDogs who swallow packaging along with candy

As a general rule from veterinary toxicology, dark chocolate and baking chocolate are the most dangerous per ounce, followed by semi-sweet, then milk chocolate, then white chocolate (which has minimal theobromine but is still high in fat and sugar). If you know the type and amount your dog ate along with their weight, the ASPCA Animal Poison Control Center can calculate whether it's a toxic dose.

🚨 Call your vet immediately if your dog shows:
  • • Vomiting or diarrhea within hours of eating Hershey's Chocolate
  • • Lethargy, collapse, or seizures
  • • Swollen face, hives, or difficulty breathing
  • • Pale or yellowish gums
  • ASPCA Animal Poison Control (888) 426-4435
  • Pet Poison Helpline (855) 764-7661
  • Find an emergency vet near you 24/7

Is There a Safe Amount of Hershey's Chocolate?

There is no safe serving at any body weight. This is not a food to portion, it is a food to keep out of reach.

There is no safe amount of Hershey's chocolate for dogs. If your dog eats any, call the ASPCA Animal Poison Control Center or your vet immediately with the type, approximate amount, and your dog's weight.

Can Popular US Dog Breeds Eat Hershey's Chocolate?

Because Hershey's covers everything from white chocolate to unsweetened baking bars, the breed picture depends heavily on which product was involved.

Chihuahua

The smallest common US breed and the one most at risk from baking chocolate specifically, where even a single square represents a serious dose.

Labrador Retriever

Labs raid baking cupboards during holiday cooking season more than any other breed, and unsweetened baking chocolate is the worst thing in there.

Boston Terrier

Compact and food-driven, with a weight low enough that a bag of Kisses can produce genuine cardiac symptoms.

Australian Shepherd

Athletic breeds already run higher heart rates, which makes theobromine's cardiac effects more pronounced and harder to distinguish from normal excitement.

Hershey's Products Ranked by Concern

Hershey's Chocolate does not show up in only one form, and the version in front of your dog changes the answer.

  • Unsweetened baking chocolate: The most dangerous chocolate in a typical US kitchen by a wide margin.
  • Special Dark bars: Substantially more theobromine per ounce than the milk chocolate bar.
  • Milk chocolate bars: The familiar version; dangerous in quantity rather than in a single square.
  • Hershey's Kisses: Small individually, but eaten by the handful, and the foil is frequently swallowed too.
  • Hershey's Syrup: Lower cocoa concentration, but easy for a dog to consume a lot of quickly.
  • Cocoa powder: Highly concentrated; a spilled container is a serious exposure.

3 Common Myths About Hershey's Chocolate and Dogs, Debunked

These ideas come up constantly in American dog-owner forums and comment sections, and a couple of them are genuinely risky to believe.

❌ Myth: "All chocolate is roughly equally dangerous, so the type does not matter"

✅ Reality: Type matters enormously. Unsweetened baking chocolate can carry ten times the theobromine of milk chocolate by weight, which means the same size piece lands in a completely different risk category.

❌ Myth: "White chocolate counts as chocolate for toxicity purposes"

✅ Reality: White chocolate contains almost no cocoa solids and therefore very little theobromine. It is still poor food for a dog, but it does not belong in the same emergency conversation as a dark bar.

❌ Myth: "Cocoa powder is safe because it is not sweet"

✅ Reality: Sweetness has nothing to do with it. Cocoa powder is among the most concentrated theobromine sources in a kitchen, and a spilled container is one of the more serious exposures we see.

Editorial Note

"When people call about chocolate, the first question is always which kind. A Hershey bar and a baking square are separated by a factor of ten, and that number decides whether the answer is monitoring at home or driving in."
