Poisons &
household hazards.

What to keep out of reach, why species and dose matter, and how to respond quickly when a pet may have been exposed.

1

Separate and secure. Move your pet away from the substance without exposing yourself. Prevent other animals from entering the area.

2

Call immediately. Contact your veterinarian, an emergency hospital, or an animal poison-control service. Do not wait for signs.

3

Bring the evidence. Keep the package, label, plant sample, photo, or vomited material safely contained. Estimate the amount and time.

“No symptoms yet” does not mean “no danger.”

Toxicity depends on the exact substance, concentration, amount, route of exposure, time since exposure, species, body weight, age, and medical history. Advice that was safe for another animal—or for a person—may be dangerous for your pet.

This page is a prevention guide, not a complete poison list or a tool for deciding whether an exposure is safe. If you are unsure, call and let a veterinary professional calculate the risk.

Danger can be ordinary-looking.

The examples below are not exhaustive. “Natural,” “organic,” “pet-friendly,” and child-resistant packaging do not guarantee safety for every animal.

01

Human medications

Pain relievers, antidepressants, stimulants, heart and blood-pressure drugs, cold medicines, sleep aids, vitamins, supplements, topical fluorouracil, and other prescriptions can cause serious poisoning.

02

Foods and drinks

Chocolate, xylitol, grapes and raisins, onions and garlic, alcohol, caffeine, macadamia nuts, raw yeast dough, high-fat scraps, and moldy food are common concerns. Product ingredients matter.

03

Plants and bouquets

True lilies and daylilies are an emergency for cats. Sago palms, oleander, azaleas, autumn crocus, cyclamen, tulip or daffodil bulbs, and many other plants can also be dangerous.

04

Cleaning and home products

Concentrated cleaners, detergents, essential oils, batteries, nicotine products, cannabis products, mothballs, paints, solvents, adhesives, and some cosmetics deserve secure storage.

05

Garage and yard

Antifreeze, de-icers, fuels, fertilizers, pesticides, herbicides, rodenticides, slug bait, compost, mushrooms, and blue-green algae can create urgent or delayed illness.

06

Pet products used incorrectly

A pet medicine can become toxic when the wrong species receives it, too much is given, products are combined, or a dog consumes an entire package of flavored chews. Never apply a dog-only flea product to a cat.

Check ingredients—not just the product name.

CHOCOLATE + CAFFEINE

Darker chocolate and concentrated cocoa generally contain more methylxanthines, but any exposure should be assessed using the product, amount, and pet’s weight.

XYLITOL

This sweetener may appear in sugar-free gum, candy, baked goods, toothpaste, supplements, and some medications. It can cause dangerous low blood sugar and liver injury in dogs.

GRAPES + RAISINS

They can cause acute kidney injury in dogs, and a reliably safe amount has not been established. Call after any suspected exposure.

ONION + GARLIC FAMILY

Fresh, cooked, dried, powdered, or concentrated forms can damage red blood cells. Repeated smaller exposures may also matter.

ALCOHOL + RAW YEAST DOUGH

Alcohol-containing drinks or products can poison pets. Rising yeast dough can expand and produce alcohol inside the stomach.

TRASH + PACKAGING

Moldy food, fatty scraps, bones, skewers, corn cobs, strings, wrappers, and snack bags can cause poisoning, obstruction, injury, or suffocation.

SPECIES-SPECIFIC EMERGENCY

Cats and lilies: treat contact as urgent.

True lilies in the Lilium group and daylilies in the Hemerocallis group can cause severe kidney injury in cats. Petals, leaves, stems, pollen, and vase water may all create risk. A cat that brushes against pollen and later grooms it can be exposed.

Do not wait for vomiting, lethargy, or appetite loss. Remove access, prevent grooming if you can do so safely, and call a veterinarian or animal poison-control service immediately. Bring the plant or a clear photo for identification.

Secure the places pets explore.

Use latched storage, inspect bouquets and plants, clean spills promptly, and supervise pets in garages, gardens, and unfamiliar yards.

Bathroom and bedroom

Lock medicines, vitamins, topical creams, nicotine, cannabis, cosmetics, essential oils, and personal-care products. Purses and overnight bags are common access points.

Laundry and cleaning areas

Store detergent pods, concentrates, bleach, disinfectants, dryer products, and drain or oven cleaners behind closed, latched doors. Keep pets away until surfaces are dry and ventilated as directed.

Garage and driveway

Antifreeze and fuels can be dangerous in small amounts. Repair leaks, absorb spills immediately, restrict access, and store containers upright in secure cabinets.

Yard and garden

Keep pets away during application of lawn or pest products and follow the label’s re-entry time. Prevent access to rodent bait, mushrooms, compost, cocoa mulch, fertilizers, bulbs, and treated standing water.

Good intentions can complicate treatment.

DO
  • Call while the product and pet are in front of you.
  • Know your pet’s approximate weight, age, health conditions, and current medicines.
  • Report the exact product, strength or concentration, amount possibly missing, exposure route, and time.
  • Follow professional instructions for skin or eye rinsing and safe transport.
  • Ask for a case number and give it to the treating veterinary hospital.
DO NOT
  • Do not induce vomiting unless a veterinarian or veterinary toxicology professional directs you.
  • Do not give hydrogen peroxide, salt, milk, oil, charcoal, food, or another “antidote” on your own.
  • Do not force water or put anything in the mouth of a weak, seizing, unconscious, or breathing-impaired pet.
  • Do not rely on an internet dose chart, social-media answer, or a pet that still appears normal.
  • Do not discard the packaging until the case is resolved.

GO TO AN EMERGENCY HOSPITAL NOW

Breathing trouble, collapse, seizures, severe weakness, or major bleeding cannot wait.

Other possible signs include vomiting, diarrhea, drooling, tremors, agitation, unusual sleepiness, stumbling, abnormal heart rate, pale/blue/brown/yellow gums, facial swelling, sudden thirst or urination changes, and loss of appetite.

Signs vary by toxin and may be delayed. If your pet is unstable, leave for emergency care while another person calls ahead when possible.
