Foods Toxic to Dogs: What Dogs Can't Eat (USA 2026)
Some everyday human foods are seriously dangerous — even deadly — to dogs, and a few are toxic in surprisingly small amounts. This guide lists the foods dogs can't eat, the warning signs of poisoning, and exactly what to do if your dog got into something, based on ASPCA and veterinary toxicology references.
Los alimentos más peligrosos que los perros no pueden comer son las uvas y pasas (insuficiencia renal aguda, incluso en cantidades muy pequeñas), el xilitol/azúcar de abedul (en chicles sin azúcar y algunas mantequillas de maní — causa bajada de azúcar y daño hepático) y el chocolate (especialmente el negro). La cebolla, el ajo, las nueces de macadamia, el alcohol y la cafeína también son tóxicos. Como la toxicidad depende del peso del perro, incluso cantidades pequeñas pueden ser peligrosas para perros pequeños. Si tu perro come alguno de estos, no esperes a los síntomas ni le provoques el vómito por tu cuenta: llama de inmediato a tu veterinario, a un hospital de urgencias o al Control de Envenenamiento de la ASPCA al (888) 426-4435.
Why some human foods poison dogs
Dogs process certain compounds very differently than we do. A chemical that is harmless to a person — like the tartaric acid in grapes, the theobromine in chocolate, or the sweetener xylitol — can overwhelm a dog's body and damage the kidneys, liver, blood cells, or heart. Because a small dog and a large dog can eat the very same amount, body weight matters enormously: a treat-sized dose for a Lab can be a poisoning for a Chihuahua. When in doubt, always assume a food is unsafe and check before sharing.
Common foods that are toxic to dogs
| Food | Why it's dangerous | Warning signs |
|---|---|---|
| Chocolate | Methylxanthines (theobromine, caffeine); darker = more toxic | Vomiting, panting, racing heart, tremors, seizures |
| Grapes & raisins | Tartaric acid → acute kidney injury; toxic in tiny amounts | Vomiting, lethargy, less urine, kidney failure |
| Xylitol (birch sugar) | In gum, candy, some peanut butters; drops blood sugar, harms liver | Weakness, wobbling, collapse, seizures |
| Onion, garlic, chives | Allium species damage red blood cells → anemia | Weakness, pale gums, dark urine (delayed days) |
| Macadamia nuts | Cause weakness and tremors in dogs | Wobbly back legs, tremors, fever, vomiting |
| Alcohol & caffeine | Coffee, tea, energy drinks, raw dough (makes alcohol) | Disorientation, vomiting, tremors, collapse |
The most dangerous, and the often-missed
Never, in any amount: Grapes and raisins (as few as a handful can cause kidney failure), xylitol (a stick or two of sugar-free gum can be life-threatening for a small dog), and chocolate — especially dark and baking chocolate. These act fast and are the ones most likely to become an emergency.
Easy to overlook: Onion and garlic hidden in leftovers, sauces, and baby food; raisins baked into trail mix, cookies, and bread; xylitol in some peanut butters (always check the label before using it to hide a pill); unbaked bread dough, which expands and ferments into alcohol in the stomach; and cooked bones, which can splinter and cause obstructions.
If your dog ate something toxic — act now
Do not wait for symptoms and do not try to make your dog vomit on your own — with some toxins that causes more harm. Instead, remove any remaining food, note what and roughly how much was eaten and when, and call for expert help immediately: your veterinarian, a 24-hour emergency hospital, the ASPCA Animal Poison Control Center at (888) 426-4435, or the Pet Poison Helpline at (855) 764-7661 (these hotlines are staffed 24/7 and may charge a consultation fee). With fast-acting toxins like grapes or xylitol, minutes matter — the sooner treatment starts, the better the outcome.
Typical US cost ranges
- Poison-control hotline consultation: about USD 75–95 per case
- Inducing vomiting / decontamination at a clinic: USD 100–300
- Overnight monitoring and IV fluids: USD 600–1,500
- Intensive care (kidney or liver failure): USD 2,000–8,000+
Acting early — a hotline call and a same-day clinic visit — is dramatically cheaper than treating full-blown kidney or liver failure days later. Many pet insurance plans cover toxin ingestion, so it can be worth keeping the poison-control numbers saved in your phone before you ever need them.
How much is dangerous, and prevention
There is no reliable safe amount for the worst offenders — grape and xylitol toxicity have been reported from very small exposures, and dark chocolate is far more potent than milk chocolate, so the danger always depends on your dog's weight and what exactly was eaten. The safest approach is prevention: keep gum, candy, baking supplies, and trail mix well out of reach, don't share table scraps, and check ingredient labels before offering any 'people food' treat.
Act fast with PetCare AI
If your dog eats something questionable, use PetCare AI to quickly gauge urgency — describe what and how much was eaten and your dog's weight, and ask the AI vet assistant "My 12 lb dog ate two raisins, is that dangerous?" to understand whether you need an emergency visit right now. Use the in-app finder to locate the nearest 24-hour hospital. PetCare AI helps you triage and act quickly, but for any suspected poisoning, contacting poison control or a veterinarian is essential — never rely on an app alone in an emergency.
Preguntas frecuentes
Mi perro comió una uva o pasa — ¿es una emergencia?
Tómalo en serio. Las uvas y pasas pueden causar insuficiencia renal aguda en perros, y algunos se han visto afectados por cantidades muy pequeñas, así que no hay una dosis segura comprobada. Llama de inmediato a tu veterinario o al Control de Envenenamiento de la ASPCA al (888) 426-4435, sobre todo con un perro pequeño, en lugar de esperar a que aparezcan síntomas.
¿Cuánto chocolate es tóxico para un perro?
Depende del tipo y del peso de tu perro. El chocolate negro y de repostería contiene mucha más teobromina que el chocolate con leche, así que cantidades menores son peligrosas. En lugar de adivinar, llama a una línea de control de envenenamiento con el peso de tu perro y el tipo y la cantidad ingerida; te dirán si es una emergencia.
¿Por qué el xilitol es tan peligroso para los perros?
El xilitol (a veces etiquetado como 'azúcar de abedul') provoca una liberación rápida de insulina en los perros, causando una bajada peligrosa de azúcar en minutos, y también puede causar insuficiencia hepática. Se encuentra en chicles sin azúcar, dulces y algunas mantequillas de maní; revisa siempre la etiqueta antes de usar mantequilla de maní para dar una pastilla.
¿Debo hacer vomitar a mi perro en casa?
No por tu cuenta. Con algunas toxinas, provocar el vómito causa más daño, y el método equivocado puede ser peligroso. Llama primero a tu veterinario o a una línea de control de envenenamiento y sigue sus instrucciones específicas.
¿A qué número de control de envenenamiento debo llamar en EE. UU.?
El Centro de Control de Envenenamiento Animal de la ASPCA es (888) 426-4435 y la Pet Poison Helpline es (855) 764-7661. Ambos están disponibles 24/7 y pueden cobrar una tarifa de consulta. Guárdalos en tu teléfono ahora para tenerlos listos en una emergencia.
