Dogs cannot safely eat chocolate. Theobromine risk rises with dark and baker’s chocolate. What to tell a veterinarian or poison hotline now.

No. Dogs should not eat chocolate. Cornell’s Riney Canine Health Center says to contact an emergency veterinarian if a dog ingests it. Darker, more bitter chocolate carries more theobromine and caffeine.
Write down the type, a weight estimate of what is missing, the time, and your dog’s weight, then call. We do not publish a homemade safe dose.
Dogs do not clear theobromine and caffeine the way people do. Cornell says those methylxanthines stimulate the nervous system and the heart and act as diuretics. That makes chocolate a toxin problem, not a treat debate.
Fatty, sugary chocolate can also upset the gut or contribute to pancreatitis. That is a second problem on top of the stimulant effect. The practical line is simpler: if it went down, you need a professional risk check, not a forum average.
Cornell’s order of concern starts with cocoa powder, then unsweetened baker’s chocolate, then semisweet and sweet dark, then milk chocolate, then cocoa bean hulls. Darker and more bitter means more methylxanthines per bite.
Pet Poison Helpline makes the same ranking in owner language: baker’s and dark chocolate are the worst common pantry items; milk chocolate has less theobromine; white chocolate has very little and is not the usual theobromine crisis. It can still be a fat-and-sugar problem. Baking cocoa, hot-cocoa mix, cacao nibs, and cocoa mulch in the garden still count as a phone-call problem.
| Type (Cornell examples) | What they publish |
|---|---|
| Milk chocolate | 1 oz per pound of body weight can be deadly |
| Unsweetened baking chocolate | As little as 0.1 oz per pound may be lethal |
Pet Poison Helpline separately writes that more than about 0.5 oz of milk chocolate per pound, or 0.13 oz of dark or semi-sweet per pound, may put a dog at risk, and that any baker’s chocolate ingestion should be treated as an emergency. Those are their thresholds, not a leftover square you “get away with.”
Remove what is left. Do not chase the dog around the house for the last crumb. Write the chocolate type, a weight estimate of what is missing, the time, and your dog’s weight. Then call an emergency veterinarian. You can also call ASPCA Animal Poison Control at 888-426-4435 or Pet Poison Helpline at 855-764-7661 (fees may apply).
Read the wrapper for xylitol, raisins, macadamia, or coffee. Say those words on the call. Do not invent syrup of ipecac, salt, or hydrogen peroxide from a comment thread. Cornell says diagnosis is usually history plus exam, and treats decontamination as a clinic decision because chocolate absorbs slowly.
Treatment, when a veterinarian chooses it, can include induced vomiting, activated charcoal, fluids, and drugs for nausea, tremors, heart rhythm, or seizures. That list is what they may do. It is not a home kit. “It was only milk chocolate” and “the brownie was small” are still call-first sentences. Stacked toxins change the case.
Cornell lists possible signs within 2 to 12 hours, lasting 12 to 36 hours or longer in severe cases: vomiting, diarrhea, thirst, urination, restlessness, fast breathing, a racing or irregular heart, hyperexcitability, tremors, incoordination, seizures, fever, coma. A calm dog is not a cleared dog.
ASPCA Animal Poison Control and Pet Poison Helpline both charge in many cases. The fee buys a risk calculation your comment thread cannot. Have the dog’s weight and age, known heart or seizure disease, the exact product name, how much is missing, the time window, and other ingredients ready before you dial. Percentage on the bar beats “dark chocolate” as a description.
Cornell and Pet Poison Helpline already publish professional calculators and clinic guidance. Those services, plus your emergency veterinarian, should do the arithmetic. A second unofficial chart would only look like permission. Keep chocolate in a closed cupboard. If you want a non-toxin breed question next, read what an Alabai actually is. Neither replaces a poison call.
Pet Poison Helpline says white chocolate is too low in theobromine to be the usual chocolate poisoning. It is still not food. Fat and sugar can make a dog sick. Call if a small dog ate a lot, or if other toxins were in the same candy.
Cornell puts cocoa powder at the top of the risk list, then unsweetened baker’s chocolate. Baking cocoa, hot-cocoa mix, and cacao nibs are not “less chocolate.” Treat any pantry cocoa product as a phone-call problem, not a leftover snack.
Not from this page. Cornell describes decontamination as a veterinary decision, including hours after ingestion because chocolate absorbs slowly. Salt, ipecac, or peroxide from a comment thread waste time and can add a second injury on top of the chocolate.
Cornell lists possible signs within 2 to 12 hours, lasting 12 to 36 hours or longer in severe cases. Absence of vomiting is not clearance. Call with the type, amount, time, and your dog’s weight even if the dog still looks fine.
No amount is a treat we endorse. Milk chocolate has less theobromine than baker’s or dark, but Cornell still publishes a lethality example for milk chocolate by body weight. Dose math belongs to a veterinarian or a poison hotline, not a leftover square.
Tell the clinic everything on the wrapper. Xylitol and grapes or raisins are separate toxin problems stacked in one bowl. Cocoa mulch in the garden is another theobromine source. One phone call should cover the whole list, not three separate guesses.
Call an emergency veterinarian first if you have one nearby. You can also call ASPCA Animal Poison Control at 888-426-4435 or Pet Poison Helpline at 855-764-7661. Fees may apply. Have type, amount, time, and dog weight ready.
