Many foods that humans eat daily are toxic — sometimes fatally — to dogs and cats. At Shivraj Pet Clinic & Lab, food toxicity is one of the most common emergency presentations we see. This guide covers the most dangerous foods and what to do if your pet eats them.
Foods Toxic to Dogs and Cats
Grapes and Raisins
Toxic to dogs — potentially toxic to cats.
Even small quantities of grapes or raisins can cause acute kidney failure in dogs. The toxic compound is not yet identified, meaning there is no safe amount. Some dogs eat a single grape and develop kidney failure; others eat a handful with no apparent effect. Because of this unpredictability, zero tolerance is the only safe approach. Do not share any grape-containing food — including juice, wine gums, or raisins in baked goods.
Onions, Garlic, and Leeks
Toxic to both dogs and cats. More dangerous to cats.
The entire allium family — onions, garlic, leeks, chives, and shallots — contains compounds that damage red blood cells, causing haemolytic anaemia. Toxicity occurs from raw, cooked, or powdered forms. The effect is cumulative — daily small amounts can build up over weeks. Indian home-cooked food shared with pets is a common source of this poisoning.
Signs: lethargy, pale gums, increased respiratory rate, orange or brown urine.
Chocolate
Toxic to dogs. Less common in cats who typically avoid sweet tastes.
Chocolate contains theobromine and caffeine, both toxic to dogs. Dark chocolate and baking chocolate are far more dangerous than milk chocolate, but no form is safe. A medium-sized dog eating a small bar of dark chocolate can develop serious toxicity.
Signs: vomiting, diarrhoea, hyperactivity, muscle tremors, seizures, cardiac arrhythmias.
Xylitol
Extremely toxic to dogs.
Xylitol is a sugar substitute found in sugar-free gum, some peanut butters, vitamin gummies, and dental products. In dogs, it causes a sudden severe drop in blood sugar (hypoglycaemia) and liver failure. Even one or two pieces of xylitol-containing gum can be fatal to a small dog.
Macadamia Nuts
Toxic to dogs.
Macadamia nuts cause weakness, hyperthermia, vomiting, and tremors in dogs, typically within 12 hours of ingestion.
Avocado
Toxic to birds and rabbits. Potentially harmful to dogs and cats in large amounts.
Persin, found in avocado flesh, skin, pit, and leaves, causes respiratory distress and fluid accumulation around the heart in birds. Keep avocado away from all pets.
Alcohol
Toxic to all pets.
Even small amounts of alcohol cause significant toxicity in pets — vomiting, disorientation, low blood sugar, low body temperature, and respiratory depression. Beer, wine, spirits, and even alcohol-containing desserts must be kept away from pets.
Raw Dough and Yeast
Toxic to dogs.
Raw yeast dough continues to expand in the warm, moist environment of the stomach, causing life-threatening bloat (gastric dilatation). Fermenting yeast also produces alcohol — creating a double toxicity.
What to Do If Your Pet Eats Something Toxic
- Do not wait for symptoms — call us immediately at 077569 65169
- Note exactly what was eaten, how much, and when
- Bring packaging or a photo of the product
- Do not attempt to induce vomiting at home without veterinary guidance
The window for effective treatment is often very narrow. If caught within 1–2 hours of ingestion, we can often prevent serious toxicity from developing. After symptoms appear, treatment becomes more complex and outcomes less certain.
