What Can Dogs Eat? The Complete Human-Food List

By Marc Brannigan, Co-Founder & CEO

Most of what is in your fridge is safe for a dog in small amounts. A short list is genuinely dangerous, and a longer list is safe only once you remove a pit, a rind, a core or a cob.

Start here: the foods that are genuinely dangerous

This is the short list, and it is the only part of the page where the answer is never a question of quantity.

• Grapes and raisins. Acute kidney injury, with no established safe amount. A single grape is a reason to call your vet. This is the most important line on the page.
• Chocolate. Theobromine and caffeine. Dark and baking chocolate are the worst.
• Xylitol. A sugar alcohol in sugar-free gum, mints, some peanut butters and some baked goods. It causes a crash in blood sugar within an hour and liver failure at higher doses.
• Onions, garlic, leeks, chives and shallots. The whole allium family damages canine red blood cells, raw or cooked, and powdered is worse than fresh, not better — our garlic guide has the mechanism. This is what rules out most leftovers.
• Macadamia nuts. Weakness in the hind legs, tremors and fever, from as little as a couple of nuts per kilogram of body weight.
• Alcohol, caffeine and raw yeast dough.
• Cooked bones. They splinter.
• Blue cheese. Roquefortine C, which dogs are unusually sensitive to.
• Anything moldy. Tremorgenic mycotoxins are a real emergency.

If your dog has eaten any of these, call your vet or an emergency line now rather than waiting for symptoms. Keep the ASPCA list bookmarked on your phone; it is the reference we check against.

How much is 10%, in practice?

For a 30 lb dog eating roughly 700 calories a day, the treat allowance is about 70 calories. That is a third of a banana, or half a cup of blueberries, or an entire cup and a half of cucumber. The difference between those three is the whole reason this page has portion columns rather than a yes-or-no list.

The portions below are for a medium dog, 20 to 50 lbs. Each linked guide has the full table by weight, from toy to giant, along with how to prepare it and which dogs should skip it.

Fruits dogs can eat

Food	Verdict	Medium dog, per day	What to know
Apples	Yes	A quarter of an apple	No core, no seeds
Bananas	Yes	A third of a banana	High in sugar, ration it
Blackberries	Yes	4 to 6 berries	Count them out
Blueberries	Yes, the best	8 to 10 berries	No prep needed
Cantaloupe	Flesh only	2 to 3 cubes	Rind causes obstructions
Mango	Flesh only	2 to 3 cubes	The pit means surgery
Oranges	Peeled only	2 to 3 segments	Peel carries limonene
Pineapple	Flesh only	2 to 3 cubes	No core, no skin
Raspberries	Yes	4 to 6 berries	Trace natural xylitol
Strawberries	Yes	2 to 3 berries	Hull and quarter them
Watermelon	Flesh only	About half a cup, diced	Best hot-weather treat
Tomatoes	Ripe only	A quarter of a medium tomato	Green fruit and vines are not
Avocado	Caution	1 tablespoon, occasionally	Pit, skin and fat are the risks

The pattern across fruit: the flesh is almost always fine and the packaging is what hurts. Pits and stones cause obstructions that need surgery, rinds do not break down, peels carry concentrated oils, and apple cores hold the seeds. Sugar is the other limit — mango and banana are close to dessert, while blueberries and raspberries are not.

Vegetables dogs can eat

Food	Verdict	Medium dog, per day	What to know
Asparagus	Cooked soft	1 to 2 spears, chopped	Raw is a choking risk
Broccoli	Yes	2 to 3 small florets	Keep under 10% of the day
Carrots	Yes	Half a medium carrot	Coins, not whole carrots
Celery	Yes	1 stalk, chopped	Chop across the strings
Corn	Kernels only	2 tablespoons	The cob is a surgical risk
Cucumber	Yes, the best	A quarter cup, chopped	~8 calories per half cup
Green beans	Yes, the best	A quarter cup, chopped	Vets recommend these
Potatoes	Cooked only	2 tablespoons	Raw and green contain solanine

Vegetables are where the genuinely useful treats are. Green beans, cucumber and celery all land around 6 to 31 calories a cup, which means you can hand them over all day without touching the calorie budget. Plain cooked pumpkin is the one to reach for with a sensitive stomach.

Protein, dairy, grains and nuts

Food	Verdict	Medium dog, per serving	What to know
Cheese	Small amounts	1 to 2 small cubes	Never blue cheese
Shrimp	Cooked, peeled	1 to 2 shrimp	Never raw, no shells
Popcorn	Plain only	A small handful	Kernels crack teeth
Almonds	No	None	Obstruction and fat risk

Two more worth naming. Plain peanut butter is a standard dog treat, because a peanut is a legume rather than a tree nut — just check the label for xylitol. Plain cooked egg, with no butter or salt, is one of the better protein toppers there is.

And one category that deserves its own warning: mushrooms. Store-bought culinary mushrooms are safe plain, and several have genuine research behind them — our guide to functional mushrooms covers those. Wild mushrooms are a different matter entirely and should never be eaten by a dog, because the dangerous species are hard to identify even for experts.

How to introduce a new food

• One new thing at a time. If something disagrees with your dog, you want to know which thing it was. This is the single most useful habit on this page.
• Start with a piece smaller than the portion above and wait a day.
• Wash it. Soft fruit and leafy vegetables are commonly sprayed, and melon rind carries surface bacteria a knife will drag through the flesh.
• Serve it plain. No butter, oil, salt, sugar or seasoning. Nothing out of a roasting pan, because roasting juices have usually met onion or garlic.
• Cut to the dog, not to the food. A whole cucumber slice, a whole baby carrot and a whole shrimp tail are all choking-shaped for a terrier.
• Watch for 48 hours after anything with a pit, a rind, a cob or a stone went missing. Repeated vomiting, straining without passing stool, refusing food or a tense, painful abdomen all mean call your vet — those are obstruction signs and the treatment window is short.

What most of these lists get wrong

Three things, consistently.

They treat "not toxic" as "good for them". Plenty of foods on this page are safe and useless. Orange is a fair example: dogs make their own vitamin C in the liver, so the headline benefit of citrus does not apply to them at all, and what is left is sugar.

They skip the preparation, which is where the actual injuries happen. Corn is not dangerous; corn on the cob is one of the most common causes of emergency abdominal surgery in dogs. Mango flesh is fine; the stone is not. That distinction is the difference between a treat and a surgery.

They inflate the risk of things that are merely unsuitable. Avocado is the clearest case. Persin is seriously toxic to birds, rabbits and horses, and dogs are far more resistant to it with no established toxic dose — the real problems for a dog are the stone and the fat. Calling it poison is wrong, and it crowds out the pit warning that actually matters.

If your dog is overweight, start here

This is the most useful thing on the page for most owners. Canine obesity is the most common preventable health problem in dogs, and the practical obstacle to a weight plan is never the diet food — it is that the dog is hungry and you feel cruel.

Cucumber, celery and green beans solve that specific problem. Chop a stalk of celery or a handful of green beans at the start of the day and work through them instead of biscuits: for a 30 lb dog that trades roughly 150 calories of treats for about 10.

It matters beyond the number on the scale. Excess weight is one of the few joint-pain levers an owner fully controls, and it changes how fast arthritis progresses. If your dog is stiff getting up, slowing on walks or hesitating at stairs, our guides to the real stages of arthritis in dogs and why a dog limps set out what to watch for and when it needs a vet rather than a diet change.

If your dog is on medication

Worth a short section, because food and drugs interact more than owners expect. Grapefruit and other citrus affect the enzymes that clear several medications. Green beans, broccoli, blackberries and cucumber all carry vitamin K, which is directly involved in clotting and therefore relevant to a dog on a blood thinner. Calcium in cheese interferes with the absorption of some antibiotics.

None of that makes these foods dangerous — it makes them worth a sentence at your next appointment. If your dog takes something daily, our guides to the common ones are worth reading first: gabapentin, Rimadyl and carprofen, trazodone, prednisone and tramadol. If you are also giving hemp or CBD, our guide to what the research says about CBD and dog medications covers the interactions that have actually been measured.

A treat with the portion already worked out

Everything above takes washing, cutting, weighing or cooking, and gives a dog something their complete food already covers. That is fine for a shared apple slice. It is less practical as the thing you reach for several times a day.

Our organic hemp dog treats come in Small Dog, 2mg, $25 and Large Dog, 5mg, $32, handmade in small batches on our own Colorado farm from organic ingredients and our full-spectrum hemp extract, and third-party tested. One biscuit is one serving — nothing to peel, core or count. For dogs who do better with a few drops on food, the hemp seed oil range covers the same ground, and the serving guide gives amounts by body weight.

Frequently asked questions

The bottom line

Keep the dangerous list on your phone — grapes and raisins, chocolate, xylitol, the onion family, macadamia nuts, alcohol, caffeine, raw dough, cooked bones and blue cheese. For everything else, the answer is a portion and a preparation rather than a yes or a no: take off the pit, the rind, the core or the cob, serve it plain, keep it under 10% of the day, and introduce one new thing at a time. If you want a treat that needs none of that arithmetic, that is what a purpose-made one is for.
