Pet poison prevention: foods, plants, and household items to keep away

This article is about prevention — the foods, plants, and household items most often involved in pet poisoning cases. It is not a treatment guide. If you suspect exposure, call a vet or a poison hotline right now. Treatment decisions depend on the substance, dose, and timing, and need to come from a professional.

Most household poison exposures in pets are accidental and preventable. Pets — especially curious dogs — explore with their mouths. The most effective protection is a layer of small habits: keep the dangerous stuff out of reach, know which items are most concerning, and have the right phone numbers ready before you ever need them. Pair this guide with our pet first aid basics and pet emergency preparedness checklist.

Common toxic foods to keep away from pets

Veterinary toxicology resources consistently flag the following human foods as toxic or potentially toxic to dogs, cats, or both. This is a starting list, not a complete one.

• Chocolate — toxic to dogs and cats. Darker chocolate is more concerning.
• Xylitol — a sweetener in sugar-free gum, candy, peanut butter, and some baked goods. Highly toxic to dogs.
• Grapes and raisins — can cause kidney damage in dogs.
• Onions, garlic, leeks, and chives — toxic to dogs and cats, including in cooked form and powders.
• Macadamia nuts — toxic to dogs.
• Alcohol and yeast dough.
• Caffeine — coffee, tea, energy drinks.
• Raw bread dough.

Common toxic plants

• Lilies — many varieties are highly toxic to cats, including pollen and water from the vase.
• Sago palm — toxic to dogs and cats; all parts of the plant.
• Tulips, daffodils, and hyacinths — bulbs especially.
• Azalea, rhododendron, and oleander.
• Autumn crocus.
• Yew.
• Many common houseplants — pothos, dieffenbachia, philodendron can irritate or be toxic.

The ASPCA maintains a searchable toxic and non-toxic plant database — useful when you want to check a specific plant by name.

Household chemicals and items

• Human medications — the most common pet poisoning category. Includes ibuprofen, acetaminophen, ADHD stimulants, antidepressants, and many prescription drugs.
• Rodenticides — mouse and rat bait. Highly toxic and unfortunately attractive to pets.
• Insecticides — both garden products and indoor sprays.
• Antifreeze — ethylene glycol is sweet-tasting and highly toxic.
• Cleaning products — bleach, drain cleaner, oven cleaner.
• Lawn and garden chemicals — herbicides, fertilizers, slug bait.
• Recreational substances, including cannabis products and edibles.

Symptoms that warrant a call

Symptoms vary widely by substance and dose, but any of the following after a possible exposure are reasons to call a vet or a poison hotline immediately — we are not listing them to encourage waiting and watching, but so you can describe what you are seeing on the phone:

• Vomiting or diarrhea, especially if sudden.
• Drooling more than usual.
• Tremors, twitching, or seizures.
• Weakness, stumbling, or collapse.
• Unusual lethargy.
• Difficulty breathing.
• Pale or yellow gums.
• Confusion or disorientation.

You do not need to confirm symptoms before calling. If you saw your pet eat something concerning, call now. The substance and the timing matter more than the symptoms.

Prevention habits that actually work

• Store medications in closed cabinets, not on counters or nightstands. Pets investigate dropped pills.
• Use trash cans with locking lids, especially for kitchen and bathroom waste.
• Keep human food out of pet reach. Counter-surfers, especially.
• Audit your houseplants. Move toxic plants to rooms the pet does not enter, or replace them.
• Read peanut butter labels for xylitol before giving any to a dog.
• Lock garage and shed chemicals.
• Pet-proof guest spaces before visitors arrive with handbags and medications.

Have the numbers ready before you need them

Save these in your phone, on your fridge, and on your pet’s profile so anyone who watches your pet can find them in seconds: your regular veterinarian, the nearest emergency veterinary hospital, ASPCA Animal Poison Control (888-426-4435), and Pet Poison Helpline (855-764-7661). A Driyu profile can keep these visible alongside your contact information, so a sitter or family member is never searching for them mid-emergency.
