Twenty-two guides about feeding a dog, one question each. Most of them answer a version of can dogs eat this, and the honest answer is almost never a plain yes or no: it is a quantity, measured against the dog's body weight. Start with the three whole-food-group guides rather than the single-food ones, because they settle more questions at once. Below the post list you will find the published toxic dose thresholds in a single table, sourced to the Merck Veterinary Manual, what actually gets reported to animal poison control, and three claims this topic repeats constantly that no veterinary source supports. If your dog has already eaten something, call a veterinarian rather than reading.Dogs
Dogs
Almost every question in this collection is a dose question wearing a yes or no costume
Sixteen of these 22 guides answer some version of "can dogs eat this." Only a handful of foods deserve a flat no. For nearly everything else the honest answer is a quantity, a body weight and a timeframe, and the guide has to say so rather than picking a side.
Below the list is the part a single article cannot carry: the published toxic doses in one table, what actually gets called in to poison control, and three claims this whole topic repeats that no veterinary source supports.
Never, depends on the dose, and generally fine
Xylitol, grapes and raisins, and raw or rising bread dough. No safe quantity is published for any of them, and for two of the three the mechanism is still not fully understood.
Chocolate, onion and garlic, macadamia nuts, fats and oils, most nuts and seeds. Real thresholds exist, they scale with body weight, and a Labrador and a Chihuahua are not in the same conversation.
Most common fruits and vegetables, plain cooked meat and fish, plain rice. Still bound by the ten percent rule further down this page, and still capable of causing an upset stomach in quantity.
The published thresholds, by body weight
These come from the Merck Veterinary Manual, which states doses per kilogram of the dog's weight. A 10 kg dog is roughly 22 pounds, a 30 kg dog roughly 66.
| Substance | Threshold | What happens |
|---|---|---|
| Xylitol | Above 100 mg/kg | Hypoglycemia, which can begin within 30 minutes or be delayed 12 to 18 hours |
| Xylitol | Above 500 mg/kg | Severe liver insufficiency or failure, sometimes not apparent for 24 to 48 hours |
| Chocolate, as methylxanthines | 20 mg/kg | Vomiting, diarrhea, excessive thirst |
| Chocolate, as methylxanthines | 40 to 50 mg/kg | Cardiac effects |
| Chocolate, as methylxanthines | 60 mg/kg and above | Seizures |
| Raw onion | 15 to 30 g/kg | Oxidative damage to red blood cells, beginning within 24 hours and peaking around 72 |
| Garlic | No figure published | Merck states only that garlic is three to five times more toxic than onion |
| Macadamia nuts | 2.4 g/kg | Weakness, tremors, ataxia within 12 hours, usually resolving in 12 to 48 |
| Grapes, raisins, tamarind | None established | Acute kidney injury. Merck treats more than one grape per 4.5 kg as reason for concern |
| Raw bread dough | None established | Gastric distension plus ethanol from fermentation. Any amount is treated as significant |
Two of these have no floor. There is no published safe amount of xylitol, and no established toxic dose for grapes at all. Merck's guidance that more than one grape per 4.5 kg of body weight may carry enough tartaric acid to be a problem is a threshold for concern, not a dose. Tartaric acid content in grapes varies from 0.35 to 2 percent, which is exactly why nobody can give you a number.
The type of chocolate matters more than the amount
Chocolate is the single most common food emergency in dogs, and the arithmetic is straightforward once you know that not all chocolate is remotely equivalent. These figures are total methylxanthines, meaning theobromine plus caffeine, which is what the thresholds above are measured against.
| Type | Per gram | Per ounce | Ounces to reach 20 mg/kg in a 10 kg dog |
|---|---|---|---|
| White chocolate | 0.04 mg | 1.1 mg | Not realistically reachable |
| Milk chocolate | 2.3 mg | 64 mg | About 3.1 oz |
| Semisweet and dark | 5.3 to 5.6 mg | 150 to 160 mg | About 1.3 oz |
| Unsweetened baking | 15.5 mg | 440 mg | About 0.45 oz |
| Cocoa powder | 28.5 mg | 807 mg | About 0.25 oz |
A 22 pound dog reaches the mild signs threshold on roughly three ounces of milk chocolate, or about a quarter of an ounce of cocoa powder. That is a factor of twelve between two things people describe with the same word. For milk chocolate specifically, Merck notes that around 62 grams per kilogram, or about one ounce per pound of dog, is potentially lethal.
None of this is a reason to wait and see. Call a veterinarian or a poison control line with the dog's weight, the type of chocolate and the time of ingestion, and let them do the calculation. The numbers here are for understanding why the answer depends so heavily on which chocolate it was.
Food is the second biggest reason people phone animal poison control
The ASPCA Animal Poison Control Center publishes its case mix each year. In 2025 it fielded calls about more than 376,000 substances, and food-related exposures made up close to a third of the list once chocolate is counted alongside general food and drink.
| Rank | Category | Share |
|---|---|---|
| 1 | Over the counter medications | 16.9% |
| 2 | Food and drink | 16.4% |
| 3 | Human prescription medications | Not published |
| 4 | Chocolate | 13.6% |
| 5 | Veterinary products | 9.1% |
| 6 | Plants and fungi | 7.5% |
| 7 | Rodenticides | 6.5% |
| 8 | Household products | 6.4% |
| 9 | Insecticides | 3.8% |
| 10 | Recreational drugs | 1.9% |
The ASPCA names the biggest contributors inside the food category directly: grapes and raisins, xylitol chewing gums, and onions and garlic. Those are the three that recur in the threshold table above, which is a useful confirmation that the theory and the phone lines agree. On chocolate the ASPCA adds that dogs are the most common culprits.
Two clarifications on that 376,000 figure. It counts substances involved in exposures rather than cases, and the ASPCA did not publish a case count for 2025. Separately, the organization states it takes more than 400,000 calls a year across all species. Anyone quoting 376,000 as a dog case count is misreading the release.
Three things this topic repeats that no veterinary source supports
- "Cooked bones are dangerous, raw bones are safe." No authoritative source says this. The ASPCA warns specifically about raw bones causing gastrointestinal injury or obstruction. Tufts advises no bones of any kind, including antlers, hooves and yak chews, on the grounds that the odds of a fractured tooth are very high. Cornell groups bones, antlers, hooves and rawhide together. The FDA warns that bones can lodge in the esophagus or trachea and fracture into sharp pieces, and draws no raw versus cooked distinction at all. The AVMA does specifically name cooked poultry bones as splinter risks, which is where the folk rule comes from, but it never endorses raw ones as the alternative. Can Dogs Eat Chicken Bones? covers what to do if one has already been swallowed.
- "The toxic dose of grapes is X per pound." There is no established toxic dose. The mechanism itself was only proposed in 2022, when researchers at the ASPCA's own poison control center published work identifying tartaric acid as the likely toxic component, after cases involving cream of tartar and tamarind. Dogs lack the organic acid transporters other species use to clear it. Because tartaric acid content varies several fold between grapes, predicting toxicity from quantity does not work, and any article giving you a precise per-pound figure has invented it.
- "The FDA proved grain free food causes heart disease," or "the FDA cleared it." Both are wrong. The FDA stopped publishing updates in December 2022, stating it would not release more until there was meaningful new scientific information. In August 2024 it confirmed it continues to pursue scientific understanding of non-hereditary dilated cardiomyopathy, that it has no definitive information indicating the diets are inherently unsafe, and that it does not know the specific connection. Research has continued outside the agency, and as of June 2026 the specific mechanism of heart injury has still not been identified. Nutritional deficiency, the original taurine theory, does not appear to be the main factor.
Ten percent, and the reason is nutrient balance rather than calories
Every guide in this collection about a food a dog can have ends in the same place, so it is worth stating once properly. The World Small Animal Veterinary Association puts it plainly: treats should always make up less than 10 percent of a dog's daily calorie intake. The American Animal Hospital Association's 2021 nutrition guidelines say the same, and add the reasoning, which is that the complete and balanced diet needs to represent at least 90 percent of intake so its nutrient profile is not diluted. UC Davis gives identical advice.
WSAVA publishes the allowance by body weight, and the numbers are smaller than most owners expect: about 14 kcal a day for a 2 kg dog, rising to about 146 kcal for a 45 kg dog. A single commercial chew can use up a small dog's entire daily allowance on its own. Apple slices, blueberries and carrot sticks all count against it.
This is the framework that makes the rest of the collection usable. A food being safe does not make it free. Watermelon is fine for dogs and still competes for the same ten percent as everything else in the treat jar. Puppy Food vs Adult Dog Food covers the other 90 percent, which is where the actual nutrition happens.
All 22 dog guides, grouped by what you are holding
The archive above runs newest first. These groups start with the whole-food-group guides, because they answer more questions per minute than the single-food ones. Age and life stage questions hand off to the pet calculators, and cat owners should start at the cat collection instead, since almost none of the doses on this page transfer between species.
Start with the master lists
Three guides that cover a whole food group at once. Read these before the single-food guides.
- What Fruit Can Dogs Eat? The Complete Safe and Unsafe Fruit List Every common fruit sorted, with the grape and raisin exclusion explained.
- What Vegetables Can Dogs Eat? The Safe and Unsafe List Where the allium family sits, and which vegetables are worth bothering with.
- Can Dogs Eat Mushrooms? Safe vs. Toxic Types Store bought versus anything growing in the yard, which is the whole distinction.
Fruit, one at a time
The five most searched individual fruits, each with portions rather than a verdict.
- Can Dogs Eat Watermelon? A Summer Fruit Guide Flesh, rind and seeds treated separately, because they are not the same question.
- Can Dogs Eat Blueberries? How Many Are Safe A rare case where the count actually matters less than the total sugar.
- Can Dogs Eat Oranges and Clementines? A Citrus Guide Peel, pith and acidity, and why small dogs react differently.
- Can Dogs Eat Dragon Fruit? A Safe Serving Guide An increasingly common question with a genuinely simple answer.
- Apples for Dogs: Juice, Sauce, Pie and Cores Four different products from one fruit, with four different answers.
Vegetables, greens and starches
Where the nightshade worry belongs, and where it does not.
- Leafy Greens for Dogs: Spinach, Kale and the Right Portions Oxalates and calcium, and why spinach is a portion question not a ban.
- Are Tomatoes and Potatoes Safe for Dogs? Ripe fruit versus green parts, which is the entire nightshade issue.
- Can Dogs Eat Sweet Potatoes? A Complete Safety and Serving Guide Cooked, plain and portioned, plus why they turn up in so many dog foods.
Protein, fat and bones
The highest stakes group in the collection. One of these is about an emergency.
- Can Dogs Eat Fish and Organ Meats? Safe Types, Liver and Sardines Vitamin A load from liver, bones in fish, and which species to avoid.
- Can Dogs Eat Chicken Bones? The Risks and What to Do What the FDA and three veterinary schools actually say, and the first hour.
- Can Dogs Have Cooking Oils? Olive, Avocado and More Fat load and pancreatitis risk, which is the real concern with oils.
- Can Dogs Have Olive Oil? Benefits, Risks and the Right Amount The one oil people ask about most, with a teaspoon-level answer.
Human staples and processed food
Two guides on the things dogs get fed by accident rather than on purpose.
- Can Dogs Eat Crackers, Bread and Baked Snacks? Salt, sugar and the raw dough exception that is genuinely dangerous.
- Tofu, Rice and Fermented Foods: Safe for Dogs? Plant proteins and fermented food, including where the garlic risk hides.
Feeding, aging and health
The five guides that are not about a single food.
- Puppy Food vs Adult Dog Food: Differences and When to Switch The 90 percent of the diet that the ten percent rule protects.
- What to Give a Dog for Diarrhea: Causes, Feeding and How to Stop It Bland diets, when to withhold food, and the signs that mean call a vet.
- How Do Dog Years Work? The Real Way Dogs Age Why the multiply-by-seven rule is wrong, and what replaced it.
- How Long Is a Dog Pregnant? The Full Timeline, Signs and Stages Gestation length, and how it is measured from breeding rather than conception.
- Dog Pregnancy Stages: A Week-by-Week Guide to the 9 Weeks What changes each week, including when nutrition needs to change.
Frequently asked questions
How much chocolate is dangerous for a dog?
It depends entirely on the type. A 10 kg dog reaches the mild signs threshold of 20 mg/kg on about 3.1 ounces of milk chocolate, 1.3 ounces of dark, or a quarter ounce of cocoa powder. Call a vet with the weight, type and timing.
What is the toxic dose of grapes for dogs?
None has been established. The Merck Veterinary Manual treats more than one grape per 4.5 kg of body weight as reason for concern, but tartaric acid content varies from 0.35 to 2 percent between grapes, which makes any precise figure unreliable.
How much xylitol is dangerous?
Above roughly 100 mg per kilogram of body weight can cause hypoglycemia, and above 500 mg/kg can cause liver failure. Hypoglycemia can appear within 30 minutes or be delayed 18 hours, and liver signs may take 24 to 48 hours.
Are raw bones safe for dogs if cooked bones are not?
No veterinary source supports that distinction. The ASPCA warns specifically about raw bones, Tufts advises against bones of any kind because of fracture risk to teeth, and the FDA warns about bones without separating raw from cooked.
Did the FDA prove grain free dog food causes heart disease?
No. The FDA paused public updates in December 2022 for lack of new science, and in August 2024 confirmed it has no definitive information that the diets are unsafe and does not know the specific connection. It has never established causation.
How many treats can a dog have in a day?
Under 10 percent of daily calories, according to both WSAVA and the American Animal Hospital Association. In practice that is about 14 kcal for a 2 kg dog and 146 kcal for a 45 kg dog, which one commercial chew can exceed.

Where to go next
For age, weight and feeding math, use the pet calculators. The cat collection covers the other species, and everything else on the site is on the Waldev homepage.
If your dog has eaten something on this page, do not use this page to decide what to do. Call your veterinarian, an emergency clinic, or the ASPCA Animal Poison Control Center on 888-426-4435, which operates 24 hours and may charge a consultation fee. Have the dog's weight, the product and the time of ingestion ready. Everything here explains published veterinary data for general understanding and does not replace a veterinarian who can examine your dog.
