Your dog just ate chocolate and you need a number, not a lecture. I am an emergency and critical care vet who has worked in Sydney and Hong Kong. The danger comes down to 3 things: the type of chocolate, the grams eaten, and your dog's weight in kg. This article gives you the dose table, the timeline of signs and the exact steps for the next hour.

Quick Answer

Call a vet now if your dog ate any dark or baking chocolate. Milk chocolate causes signs from about 9 g per kg of body weight. That is roughly 90 g for a 10 kg dog. Signs start 2 to 12 hours after eating. They can last over 24 hours. Do not make your dog vomit at home. Your vet does this safely.

How urgent is this?

Match your dog to a row below. This uses a mg/kg dose (milligrams of the chemical per kilogram of your dog). The sum is explained further down, under the dosing heading.

Why is this happening?

Chocolate contains theobromine and caffeine, 2 stimulant chemicals grouped as methylxanthines (the stimulant chemicals in chocolate). Your dog absorbs theobromine slowly, with blood levels peaking about 10 hours after eating, and clears it slowly too. The half-life is 17.5 hours. Half-life is the time it takes half the dose to clear from the blood. This means half the dose is still in the blood 17.5 hours after eating. That slow clearance is why a dog can look fine at hour 4 and be trembling at hour 10.

The strength of the chocolate decides everything. The same 30 g square carries roughly 7 times more methylxanthine as baking chocolate than as milk chocolate. The wrapper matters as much as the amount.

Your vet also rules out the look-alikes hiding in the same snack. Sugar-free chocolate can contain xylitol, a sweetener that drops blood sugar in dogs and is a separate emergency; see Xylitol poisoning in dogs: signs and what to do. Chocolate-covered raisins, chocolate with macadamia nuts, and foil wrappers swallowed whole each bring their own problem. Grapes and raisins can also damage the kidneys at unpredictable doses; see Grapes and raisins poisoning in dogs.

How much chocolate is dangerous for my dog?

Weigh your dog in kg and read the wrapper for the weight in g. Multiply the grams eaten by the mg/g figure for that chocolate. Divide the answer by your dog's weight in kg. The result is the dose in mg/kg, which is the number your vet needs. Example: an 18 kg dog eats 30 g of dark chocolate: 30 x 5.7 / 18 = 9.5 mg/kg.

These are the dose thresholds for dogs.

The 40 mg/kg and 60 mg/kg lines are bands, not exact numbers. Heart signs start somewhere between 40 and 50 mg/kg, and individual dogs vary within that range. The call-now rule below does not change.

The table below shows the grams of each chocolate that reach 20 mg/kg. Dark chocolate is calculated at the top of its range, 5.7 mg/g.

Double these amounts for the heart-sign dose of 40 mg/kg. Triple them for the seizure dose of 60 mg/kg. A 5 kg dog eating 20 g of baking chocolate reaches 64 mg/kg. A 30 kg dog eating the same 20 g reaches about 11 mg/kg. I recommend calling your vet at 20 mg/kg or higher. Round your estimate up, never down.

Signs that mean emergency

Go to a vet now if you see any sign on this list.

• Heart racing or pounding at rest. Heart effects begin at 40 to 50 mg/kg. Waiting risks an abnormal rhythm that fluids alone cannot fix.
• Muscle tremors or stiff, twitching legs. Tremors come before seizures. Waiting means the seizure can start in the car.
• Seizure. Seizures start at 60 mg/kg and above. Every minute of seizing raises body temperature and strains the heart.
• Collapse or cannot stand. This dog needs IV fluids (fluid given through a vein) and heart monitoring now.
• Vomiting more than once, or vomiting blood. Repeated vomiting causes dehydration and delays treatment.
• Fast or labored breathing. A 2.2 kg puppy on 176 mg/kg had lung fluid within 4 hours. That is an extreme dose in a very small dog. At ordinary doses, expect signs within 2 to 12 hours.

Theobromine has a half-life of 17.5 hours. Signs build during the first 24 hours rather than fading. A dog who waits at home through the night arrives sicker, not safer.

What to do right now

1. Take the remaining chocolate away from your dog.
2. Find the wrapper. Note the type and the weight in g or oz.
3. Estimate how much is missing, and guess high rather than low.
4. Use your dog's weight in kg from the last vet visit.
5. Multiply grams eaten by the mg/g figure, then divide by kg.
6. Call your vet anyway if you cannot measure or calculate the amount.
7. Call your vet, or an animal poison hotline if you cannot reach one.
8. Tell them the type of chocolate.
9. Tell them the grams eaten, or your best estimate.
10. Tell them your dog's weight in kg and the calculated dose in mg/kg.
11. Go now if the dose is 20 mg/kg or higher.
12. Go even if more than 1 hour has passed. Chocolate fat slows stomach emptying. The vet can often still remove it.
13. Go now for any dark or baking chocolate in a dog under 10 kg.
14. Do not make your dog vomit with hydrogen peroxide, salt, mustard or ipecac (vomiting syrup).
15. Do not give activated charcoal (a poison-absorbing powder) bought from a pharmacy.
16. Leave fresh water available on the way out.
17. Bring the wrapper, the time of eating and your dog's weight.

What will the vet do?

The first job is the sum you just did, checked against the wrapper and the scale. Your vet then decides whether the chocolate is still in the stomach and worth removing. Chocolate is high in fat, so it often sits in the stomach well past the first hour. If it is still there, an injection makes your dog vomit under supervision. This is the safe version of the home remedy you skipped.

Activated charcoal binds methylxanthines in the gut so less is absorbed. The dose, the IV fluids that go with it and the blood sodium checks afterwards stay with the vet. This is because charcoal pulls water into the gut. One dog given charcoal after eating chocolate brownies developed severe hypernatremia, a dangerous rise in blood sodium, and needed a ventilator before going home 57 hours later. This is why home dosing is off the table.

For doses above 40 mg/kg, expect IV fluids and an ECG (a heart tracing test) to watch the heart rhythm. Your vet may also give anti-nausea drugs and drugs to slow the heart or stop tremors as needed. Because the half-life is 17.5 hours, a dog at the heart-sign dose stays in hospital for 24 hours or more.

Recovery is the good news. Of 156 dogs that ate chocolate, 112 never developed signs. Of the 44 that did, the most common problems were agitation, tremors and vomiting, and 28 had a racing heart. With vomiting induced by injection, charcoal, IV fluids and heart-rate control, 43 of the 44 recovered. Most dogs given appropriate care do well, and the calculated dose plus the signs in front of the vet drive the plan. Even the 2.2 kg puppy at 176 mg/kg with fluid in the lungs went home by day 6. It recovered after oxygen, fluids and a diuretic (a drug that helps the body pass extra fluid).

Common mistakes owners make

1. Waiting to see if signs appear. Signs can take 6 to 12 hours to show. By then, the chocolate has left the stomach and vomiting no longer helps.
2. Inducing vomiting with hydrogen peroxide or salt. Peroxide damages the stomach lining and esophagus and can be inhaled into the lungs. Salt causes hypernatremia, a sodium overdose that is its own emergency.
3. Giving activated charcoal from the pharmacy. Charcoal needs a vet-chosen dose with fluids and sodium checks. One dog given charcoal for chocolate reached a blood sodium of 174 and needed a ventilator.
4. Treating 1 vomit as the all-clear. With a 17.5 hour half-life, the theobromine already absorbed keeps working for more than a day.
5. Treating all chocolate as the same. Baking chocolate carries 16 mg/g against 2.3 mg/g for milk. For a 20 kg dog, a 30 g square of baking chocolate means a vet visit at 24 mg/kg. The same square of milk chocolate means watch-and-wait at 3.5 mg/kg.
6. Guessing low on the amount. Owners find the empty box after the vet visit, not before; round up and let the vet round down.

How to prevent it

Dogs reach the chocolate you thought was out of reach: a coffee table, an open handbag, a gift bag under a tree. Store chocolate above counter height in a closed cupboard. Treat baking chocolate and cocoa powder like medicine, because 6 g of baking chocolate brings a 5 kg dog to the 20 mg/kg line. Christmas and Easter bring chocolate down to floor level: in UK dogs, chocolate poisoning was almost 5 times more likely at Christmas and twice as likely at Easter, and dogs under 4 years were the most exposed. Check under the couch and inside kids' bags after each holiday.

A solid "leave it" cue buys you the 2 seconds needed to take a bar back.

A bored dog goes looking, and the coffee table is where the looking ends. Ten minutes of nose work at floor level spends that energy on something that is not your handbag. Scatter the dog's own dinner through a snuffle mat to set this up.

FAQs

How much chocolate will kill a dog?

There is no single fatal number, because the risk depends on chocolate type, grams eaten and your dog's weight. Seizures start at 60 mg/kg and above, and I treat that dose as life-threatening. Of 44 dogs that developed signs after chocolate, 43 survived with treatment. A 2.2 kg puppy at 176 mg/kg survived with intensive care. A dog who reaches the vet early has good odds.

How long after eating chocolate do symptoms start in dogs?

Signs start 2 to 12 hours after eating, and theobromine peaks in the blood at about 10 hours. A 2.2 kg puppy that ate a 200 g chocolate cake had breathing trouble within 4 hours, then a fast heart, fast breathing and fluid in the lungs. Because theobromine has a 17.5 hour half-life, a dog who looks normal at hour 4 has not passed the danger window, and I recommend watching for a full 24 hours.

Is white chocolate dangerous to dogs?

White chocolate carries almost no methylxanthines, so it does not cause chocolate poisoning at normal amounts. The fat and sugar can still cause vomiting or diarrhea. A large fatty meal can also trigger pancreatitis (an inflamed pancreas) in some dogs. Call your vet if vomiting continues past 2 episodes or your dog stops eating; see Why is my dog vomiting and when to worry.

Can a small amount of chocolate hurt a small dog?

Yes, because the dose is per kg. A 5 kg dog reaches 20 mg/kg from 43 g of milk chocolate or 6 g of baking chocolate. A 30 kg dog would shrug off these same amounts. The 2.2 kg puppy reached 176 mg/kg from a homemade chocolate cake.

Can cats get chocolate poisoning?

Cats rarely eat chocolate, so this is a dog problem in practice. The same methylxanthines are poisonous to cats, so if your cat does eat chocolate, do the same sum and call your vet.

Closing

Do the sum now and call before hour 6, not after. My opinion is that the owners who call at 20 mg/kg and hear "come in for a quick check" have a better night than the ones who call at hour 10 with a dog who cannot stop shaking.

If you are sitting up tonight watching a dog who found the chocolate, log the time, the grams and each vomit in ASK A VET™, where you can track symptoms hour by hour and ask a vet directly in the app when something changes.

Chocolate toxicosis is a dose-per-kilogram problem with a long toxicokinetic tail, so the calculated methylxanthine dose and the signs in front of you decide the plan together. This version gives the dose thresholds, the kinetics behind the monitoring window, the decontamination decision by time since ingestion, and cited doses for complications above 40 mg/kg [1][2]. Of 156 dogs that ate chocolate, 44 developed signs and 43 of those survived [3].

Clinical summary

Mild signs begin at about 20 mg/kg of total methylxanthines, cardiotoxic effects at 40 to 50 mg/kg and seizures at 60 mg/kg and above [1][2]. Signs start 2 to 12 hours after ingestion, plasma theobromine peaks at about 10 hours, and the theobromine half-life is 17.5 hours [1][2]. Admit any dog at or above 40 mg/kg, or with tachycardia, tremors or seizures at any calculated dose, for ECG monitoring and IV fluids [1]. The 20 to 40 mg/kg band gets same-day emesis when clinically normal (effective decontamination within 2 to 4 hours carries a good prognosis [2]; chocolate fat slows gastric emptying), then observation; under 20 mg/kg with no signs goes home with a 24 hour watch derived from the half-life and a written return trigger [1]. Mortality among symptomatic dogs was below 3% [3].

Triage tiers

Pathophysiology and toxicokinetics

Theobromine and caffeine competitively antagonize adenosine receptors, which produces CNS stimulation, diuresis, vasoconstriction and tachycardia [1]. They raise intracellular calcium in striated muscle (the mechanism behind rigidity and tremors), inhibit phosphodiesterase, may raise circulating epinephrine and norepinephrine, and compete at CNS benzodiazepine receptors [1].

Caffeine is absorbed rapidly; theobromine is absorbed about 10 times more slowly and peaks in plasma at about 10 hours [2]. After hepatic metabolism the methylxanthines undergo enterohepatic recycling and are excreted in urine as metabolites and unchanged parent compound [1]. The theobromine half-life is 17.5 hours and the caffeine half-life 4.5 hours [1]. Methylxanthines and their metabolites are reabsorbed across the bladder wall, the basis for urinary catheterization in the recumbent patient [1]. Signs are reported from 2 to 4 hours after ingestion [2] and within 6 to 12 hours [1]. The theobromine LD50 in dogs is reported as 250 to 500 mg/kg [1]; life-threatening arrhythmias and CNS dysfunction are the fatal mechanisms, and the fat load can trigger pancreatitis [1].

Other stimulant toxicoses present the same way: caffeine tablets at about 100 mg each [1], amphetamines, pseudoephedrine, cocaine and guarana. Take the co-ingestant history at the same time: xylitol in sugar-free chocolate (see Xylitol poisoning in dogs: signs and what to do), chocolate-coated raisins (see Grapes and raisins poisoning in dogs), macadamia nuts, coffee beans and foil.

Dose calculation and thresholds

Dose in mg/kg = grams ingested x mg/g for the product, divided by body weight in kg. Use the upper figure of any content range and the owner's upper estimate. Worked example: an 18 kg dog eats 30 g of dark chocolate: 30 x 5.7 = 171 mg, and 171 / 18 = 9.5 mg/kg, below the 20 mg/kg threshold [1].

Thresholds: mild signs at 20 mg/kg, cardiotoxic effects at 40 to 50 mg/kg, seizures at 60 mg/kg and above [1][2]. Of 44 dogs with signs, 28 had eaten dark or bitter chocolate [3]. Treat the lines as bands: susceptibility varies with the individual, an empty stomach and the product [1]. Among 185 UK dogs whose dose could be calculated, 75 (41%) had eaten less than 20 mg/kg [4].

The table gives the grams that reach 20 mg/kg at the content figures above [1]; double for the 40 mg/kg cardiac band, triple for the 60 mg/kg seizure band [1].

Clinical signs by severity

Onset is 2 to 12 hours [1][2]. Initial signs are nausea, vomiting, diarrhea, polydipsia and polyuria; progression runs to restlessness, hyperactivity, tachypnea, ataxia, tremors, seizures, weakness and coma, with arrhythmia, hypertension and hyperthermia [1]. Death follows arrhythmia or CNS dysfunction [1].

Among 44 dogs with signs, the reasons for presentation were agitation (33), tremor (22), vomiting (21), panting (11), polyuria and polydipsia (7) and diarrhea (2); examination found sinus tachycardia in 28, tachypnea or panting in 14, hyperthermia in 10 and dehydration in 7 [3]. Of the 34 with abnormal results, 23 had hyperlactatemia, 16 hypokalemia, 16 mild hyperglycemia and 14 mild ALT and AST elevation [3]. At the extreme, a 2.2 kg puppy that ate about 176 mg/kg from 200 g of homemade chocolate cake had dyspnea at about 4 hours, a heart rate of 170 bpm and a respiratory rate of 80 at 5 hours, and non-cardiogenic pulmonary edema on radiographs [5].

Red flags:

• Persistent sinus tachycardia or premature ventricular contractions. Cardiotoxic band 40 to 50 mg/kg [1]; 28 of 44 symptomatic dogs [3].
• Tremors or rigidity. One step before seizures [1]; 22 of 44 symptomatic dogs [3].
• Seizure. Expected from 60 mg/kg [1]; recorded 4.5 hours after ingestion at 88.3 mg/kg [14].
• Hyperthermia. 10 of 44 symptomatic dogs [3]; listed among the terminal signs [1].
• Tachypnea, cyanosis or crackles. Pulmonary edema at 4 hours in the 2.2 kg puppy [5].
• Bradycardia or coma. Late-stage signs [1].

Telephone triage advice

Collect body weight in kg, the product, the grams missing at the upper estimate and the time of ingestion, and calculate on the line. Come now for 20 mg/kg or above [1], for any sign already present, for dark or baking chocolate in a dog under 10 kg, for any puppy and for any unmeasurable amount.

No home emesis. Prehospital emesis has no evidence of benefit in toxin ingestion and carries risk, so routine emesis at home is advised against and the animal is presented to a veterinary facility as soon as possible [6]. Oral 3% hydrogen peroxide produced gastric mucosal lesions in every dog given it, worse at 24 hours, with esophagitis in some [8]; salt causes hypernatremia. The exception is a remote location where a veterinarian or a poison center advises field emesis because no clinic is reachable [6]. Leave water available. Bring the wrapper, the last recorded weight, the time of ingestion and any vomitus in a bag.

Decontamination, treatment and monitoring

Emesis. Decontaminate the dog that presents before signs develop [1]; effective decontamination within 2 to 4 hours of ingestion carries a good prognosis [2], and chocolate fat slows gastric emptying, so a later presentation is judged on the dog's state, the size of the ingestion and what comes up, not the clock. Among 375 UK dogs, 26% presented within 1 hour and 56% within 6 hours [4]. Do not induce in a dog that is tremoring, seizing, obtunded or already vomiting. Options: apomorphine 0.03 mg/kg IV produced emesis within 10 minutes in 22 of 25 dogs and 0.06 mg/kg intranasally in 18 of 25, against 14 of 25 for ropinirole eye drops, 6 of 25 for the SC route and 4 of 25 for the compounded injectable given transconjunctivally [9]. Ropinirole 3.75 mg/m2 to the eye produced vomiting in 95% of 100 dogs within 30 minutes, median 10 minutes [10]; in an emergency-room comparison its first-dose success was 81% against 99% for IV apomorphine, with a median time to emesis of 8.6 against 1.6 minutes and rescue antiemetics needed in 37% against 0% [11]. Apomorphine and 3% hydrogen peroxide were similarly effective (94% and 90%) with mild adverse effects in 14% [7], but hydrogen peroxide injures the gastric mucosa [8], so it has no place in the clinic either.

Activated charcoal. The cited dose is 1 to 4 g/kg PO, repeated every 3 hours for up to 72 hours in symptomatic animals because of enterohepatic recycling [1]; multiple doses are the cited mainstay with supportive care [2]. Hypernatremia is the risk argued against it. In 96 dogs given a single dose with or without sorbitol, no dog developed hypernatremia (sodium above 155 mEq/L) and median sodium fell rather than rose at every checkpoint to 48 hours [12]. In 97 dogs given 2 to 6 doses, 95 of them (98%) on IV fluids, no dog exceeded 155 mEq/L and all survived [13]. The counter-case: a 7-year-old Corgi at 88.3 mg/kg, given emesis, maropitant and charcoal with sorbitol before transfer, seized at 4.5 hours, reached a sodium of 174 mmol/L with neurologic signs and azotemia, needed ventilation, and went home at 57 hours with vestibular signs that resolved within 10 months [14]. The protocol that follows: charcoal for the high-dose patient; IV fluids every time; sodium at presentation and at 6 to 12, 12 to 24 and 24 to 48 hours, the checkpoints at which the two series measured it [12][13]; repeat doses only in the monitored inpatient whose dose justifies them, with vomiting controlled (metoclopramide 0.2 to 0.4 mg/kg SC or IM) [1].

IV fluids. Fluid diuresis supports cardiovascular function and hastens urinary excretion of methylxanthines [1]; forced diuresis was part of the treatment in the 43 survivors [3]; rate and type per your formulary. Hypokalemia affected 16 of the 34 dogs with abnormal results, so check potassium at admission [3]. Erythromycin and corticosteroids are avoided because they interfere with methylxanthine excretion [1].

Antiemetics. After emesis is complete and never before it: metoclopramide 0.2 to 0.4 mg/kg SC or IM [1], or maropitant per your formulary.

Tachyarrhythmia. Correct hypovolemia, hyperthermia and anxiety first. For ventricular tachyarrhythmias, lidocaine 1 to 2 mg/kg IV to effect, then a constant-rate infusion per your formulary; lidocaine is not used in cats [1]. If lidocaine fails, metoprolol or propranolol 0.02 to 0.06 mg/kg slow IV, no faster than 1 mg per 2 minutes, repeated and increased to effect; metoprolol is preferred because propranolol can slow renal excretion of methylxanthines [1]. Esmolol was the beta blocker used in the 156-dog treatment protocol [3]. For bradycardia, atropine 0.01 to 0.02 mg/kg IM or SC [1]. The puppy with pulmonary edema went home on day 6 after IV fluids, oxygen, furosemide 2 mg/kg IV three times daily, a bronchodilator and an antiemetic [5].

Tremors and seizures. Diazepam 0.5 to 2 mg/kg slow IV, or barbiturates [1]; methocarbamol for tremors, and levetiracetam or general anesthesia for refractory seizures, per your formulary. Because methylxanthines compete at benzodiazepine receptors [1], a partial response to the first diazepam dose is a reason to escalate rather than repeat.

Urinary catheter. Place one in the recumbent patient, because methylxanthines and their metabolites are reabsorbed across the bladder wall [1]; walk the ambulatory patient to void at frequent intervals.

Monitoring and duration. Continuous ECG in the cardiac band and above, temperature, acid-base and electrolytes [1], and sodium on the charcoal schedule [12][13]. Plan from the 17.5 hour half-life [1]: the cardiac-band dog stays on the ECG through at least 1 half-life, and the dog that seized stays until sign-free for a full half-life. The hypernatremic Corgi went home at 57 hours [14] and the puppy with pulmonary edema on day 6 [5]. With that care 43 of 44 symptomatic dogs survived [3].

Common management errors

1. Calculating with the lower content figure or the owner's low estimate; dark chocolate runs to 5.7 mg/g [1].
2. Refusing emesis at hour 3 because a fixed window has passed; the good-prognosis window is 2 to 4 hours [2] and chocolate fat slows gastric emptying, so the decision rests on the dog and the dose.
3. Charcoal for the low-dose, asymptomatic dog; 41% of dose-known UK cases were below 20 mg/kg, and 34 of the 75 non-toxic cases were still given apomorphine [4].
4. Charcoal without fluids and without a sodium check [12][14].
5. Antiemetic before emesis.
6. A beta blocker for a sinus tachycardia that hypovolemia, hyperthermia or fear explains, and no ECG in a dog above 40 mg/kg [1].
7. Discharge at 6 hours because the dog looks normal; onset runs to 12 hours and the half-life is 17.5 hours [1].
8. A full bladder in a recumbent patient [1].
9. Erythromycin or a corticosteroid during recovery [1].

Prevention counseling

Chocolate goes above counter height in a closed cupboard, and baking chocolate and cocoa powder are treated like medication: 6 g of baking chocolate brings a 5 kg dog to the 20 mg/kg line [1]. Cocoa mulch at 9.1 mg/g goes on the list for any client with a garden [1]. Chocolate exposure in 375 UK dogs was 4.7 times more likely at Christmas and 2 times more likely at Easter than at other times of year, and dogs under 4 years were the most exposed [4]. A trained "leave it" cue and floor-level nose work give a bored dog a job; the owner version expands on both.

Clinical FAQs

Is emesis still worth inducing 4 hours after ingestion?

Yes for the clinically normal dog with a meaningful calculated dose. The good-prognosis window for decontamination is 2 to 4 hours [2], chocolate fat slows gastric emptying, and the yield is judged by what comes up.

Should activated charcoal be repeated for chocolate?

Enterohepatic recycling is the argument for it, and the cited schedule is every 3 hours for up to 72 hours in symptomatic animals [1]; in 97 dogs given 2 to 6 doses on fluids no dog became hypernatremic [13]. Repeat only in the hospitalized high-dose patient on fluids, with sodium checked at 6 to 12, 12 to 24 and 24 to 48 hours [12][13], because a single charcoal dose with sorbitol preceded a sodium of 174 mmol/L in the Corgi [14].

Do cats need the same protocol?

Chocolate is toxic to every species [1], so run the same calculation and downstream protocol, without lidocaine [1]. Cats are harder to make vomit: among 316 Australian veterinarians surveyed, emesis succeeded in 58% of cats against 99% of dogs, and most use IM dexmedetomidine or medetomidine for cats [16]. Dexmedetomidine IM or IV produced emesis in 13 of 16 cats at a median dose of 7 mcg/kg (range 0.96 to 10), where hydrogen peroxide produced none in 3 [15].

Bottom line

Calculate with the upper content figure and the upper estimate of grams, decontaminate the clinically normal dog, and keep every dog at or above 40 mg/kg on an ECG through at least one 17.5 hour half-life [1]. My opinion is that the sodium check after charcoal matters more than the second charcoal dose.
