Halloween and Everyday Hazards: Foods and Plants That Are Toxic to Pets
Many of the most common pet poisonings involve things already in your home. Halloween adds candy, decorations and visitors, which makes this a good time to review what is unsafe.
Foods
- Chocolate, especially dark and baking chocolate. Toxic to dogs and cats.
- Xylitol, a sweetener in sugar-free gum, candy, some peanut butters, baked goods and toothpaste. Even small amounts can be dangerous to dogs.
- Grapes and raisins, which can cause kidney failure in dogs.
- Onions, garlic, chives and leeks
- Macadamia nuts
- Alcohol and raw yeast dough
- Caffeine
- Fatty scraps and cooked bones, which can cause pancreatitis or obstructions
Halloween specifics
- Candy: Keep trick-or-treat bowls and bags out of reach, including wrappers, which can cause intestinal blockages.
- Glow sticks: Not usually deadly but can cause drooling and distress.
- Decorations: Candles, fake cobwebs, small parts and cords are chewing or entanglement hazards.
- Costumes: Only if your pet tolerates them. Make sure they do not limit vision, hearing, breathing or movement.
- Door traffic: Frequent doorbell rings and open doors increase the risk of escape. Consider a gate or a quiet room.
- Pumpkins: Plain pumpkin is generally safe in small amounts, but decorated or moldy pumpkins and candles are not.
Plants
- Lilies are extremely dangerous to cats. Even pollen or vase water can cause kidney failure.
- Sago palm is highly toxic to dogs and cats.
- Azaleas, oleander, tulip and daffodil bulbs, and autumn crocus are also hazardous.
The ASPCA maintains a searchable toxic and non-toxic plant list online. Check it before you bring a new plant home.
Other common household risks
- Human medications such as ibuprofen, acetaminophen and antidepressants
- Rodent bait, slug bait and some insecticides
- Antifreeze, which can taste sweet to animals
- Cannabis products and edibles
- Essential oils and some cleaners
Prevention tips
- Store food, medications and cleaning products in closed cabinets.
- Use pet-proof trash cans.
- Tell guests and children not to share food with pets.
- Provide your sitter with a list of hazards in your home, and the poison control numbers.
Being prepared makes a poisoning scare less frightening, and quick action greatly improves the outcome.
