Telling safe household foods from toxic ones for pets
Not everything you eat is good for a dog or cat: here is which leftovers you can share in small amounts, which to avoid, and which are dangerous even in tiny quantities.

Almost every case of household poisoning starts not with malice but with a morsel given out of affection. A square of chocolate left on the table, the raisins in a cake, a sauce made with onion: harmless to us, yet capable of becoming an emergency for a dog or cat. The trouble is that memory alone is not enough, because toxicity depends on the substance, the dose per kilogram of body weight and sometimes the species. This guide is not a list to memorise, it is a method for deciding before you give something: which foods are an absolute no, which can be shared with judgement, and how to act when you are unsure. Because with genuine toxins the rule is not moderation, it is total abstention.
First rule: when in doubt, do not give it
The most common mistake is not knowingly giving a dangerous food, it is giving it without knowing. That is why the most useful rule is also the simplest: if you are not certain a food is safe for the species and at the amount you are about to offer, do not give it and check first. A morsel postponed has never harmed anyone, one given out of habit certainly has.
- Toxicity depends on weight: the same amount of chocolate a large dog clears can poison a small one.
- Dogs and cats do not react the same way: some substances hit cats hardest, because they metabolise things differently.
- Form matters too: dark chocolate, onion powder and raisins are more concentrated and so more dangerous than their fresh or diluted equivalents.
- Many foods are not toxic but unsuitable: fatty, salty or sugary items cause digestive upset even without being poisons.
The stop list: never, in any amount
These foods are not to be managed in moderation, they are to be excluded. With some the dangerous threshold is high, with others a few grams are enough, and since you cannot calculate the dose on the spot the safe choice is a flat no. Keep them out of reach, not merely away from the bowl.
| Food | Main risk | Species most affected |
|---|---|---|
| Chocolate and cocoa | Theobromine, effects on heart and nerves | Dog and cat |
| Grapes, raisins and grape juice | Acute kidney damage | Dog |
| Onion, garlic, leek, shallot | Destruction of red blood cells | Cat more than dog |
| Xylitol (sweetener) | Blood sugar crash, liver damage | Dog |
| Alcohol and raw yeast dough | Nervous depression, gastric bloat | Dog and cat |
| Coffee, tea, caffeine drinks | Cardiac and nervous stimulation | Dog and cat |
| Macadamia nuts | Weakness, tremors, fever | Dog |
| Cooked bones | Splinters, perforations and blockages | Dog and cat |
If they have already eaten the wrong thing
If you suspect the animal has swallowed a toxin, minutes count and improvising causes harm. Not every substance is treated the same way, and some home measures, such as inducing vomiting, make things worse in certain cases. Follow a clear sequence instead of searching for remedies online while time slips away.
Remove the source at once
Take away whatever they were eating and keep the packaging or a sample: knowing what and how much was ingested changes the management.
Estimate amount and timing
Note how much they took, in what form and how long ago. These are the first things anyone you call will ask for.
Call the vet or a poison centre
Phone before doing anything. Describe the substance, the estimated dose, the animal's weight and any symptoms, and do exactly what they tell you.
Do not induce vomiting on your own
With some substances, such as caustics or yeast dough, vomiting worsens the damage. Only trigger it if a professional explicitly tells you to.
Watch and report the symptoms
Vomiting, tremors, drooling, trouble standing or changes in behaviour must be reported at once, because they guide the urgency.
Be ready to leave
If they tell you to come to the clinic, bring the product packaging and the notes you took: they save precious time on arrival.
Frequently asked questions
- My dog stole a small piece of chocolate: should I worry?
- It depends on the type of chocolate, the amount and the dog's weight. Dark chocolate and cocoa are far more concentrated than milk chocolate, and a small dog reaches the dangerous dose at amounts a large dog would clear. Do not wait for symptoms to appear: weigh how much was taken, check the type on the wrapper and call your vet or a poison centre, who will tell you whether to simply watch or to act.
- Can I give leftovers from my plate as a treat?
- Only with heavy selection. A small piece of lean cooked meat with no seasoning is fine, but prepared dishes often contain salt, spices, onion, garlic or excess fat that make them unsuitable or dangerous. The risk is not only one toxic ingredient, it is the habit: daily leftovers add weight and unbalance the ration. Keep them a rare exception and choose only foods you know to be safe.
- Why is onion more dangerous for cats?
- Onion, like garlic, leek and shallot, damages red blood cells, and cats are especially sensitive to this kind of damage because of how they metabolise certain substances. The insidious part is that the risk is not limited to fresh onion: onion powder, highly concentrated, hides in stock cubes, ready made sauces and baby foods. That is why any food containing it should be avoided, even in traces.
- Are bones good or bad?
- Cooked bones should always be avoided: cooking makes them brittle and they splinter, which can injure the mouth, perforate the gut or cause blockages. Even raw bones, often described as natural, carry risks of fragmentation, dental damage and bacterial contamination. If you want to offer something to chew, there are products designed for the purpose and more predictable: discuss the choice with your vet rather than handing over the bone from dinner.
What to do next
Treat the toxin list as a stop list: chocolate, grapes and raisins, onion and garlic, xylitol, alcohol, caffeine, macadamia and cooked bones must not be given in any amount. Safe foods, such as lean cooked meat and some vegetables, stay an occasional reward within a tenth of the day's calories. When in doubt do not give it, and if ingestion happens call your vet or a poison centre at once with weight, substance and dose to hand.
