As pet parents, we think of our furry companions as part of the family. We cherish the unique bond we share with them and strive to create a home environment that is as safe and loving as possible. While we’re careful to secure obvious hazards, many everyday items hiding in plain sight can be surprisingly toxic to our curious pets.
At Bell Parkway Veterinary Hospital, we believe the best care is personalized care that honors the special relationship you have with your best friend. A crucial part of that care is knowledge. This guide will help you identify ten common household items that can be poisonous to pets, so you can better protect your cherished family member.
1. Human Medications
One of the most common reasons for an emergency vet visit is a pet ingesting medicine intended for people. A pet’s system processes drugs very differently from a human’s, and what might be a helpful dose for you could be extremely dangerous for them.

Over-the-counter pain relievers like Acetaminophen (Tylenol) are especially toxic to cats, leading to severe liver damage and impairing their blood’s ability to carry oxygen. Likewise, antidepressants, heart medications, and even some vitamins can cause serious harm. Always keep all medications, for both people and pets, sealed and stored in a high cabinet where your pet cannot possibly reach them.
2. Common Houseplants
Plants can brighten up a home, but it’s important to choose them with your pet’s safety in mind. Many popular indoor and outdoor plants contain toxins that can cause anything from mild stomach upset to severe organ failure.
- Lilies: All parts of a true lily (such as Easter, Tiger, or Asiatic lilies) are extremely poisonous to cats. Even lapping up water from the vase or grooming a few grains of pollen off their fur can cause rapid and fatal kidney failure.
- Sago Palm: This stylish plant is highly toxic to both dogs and cats. The seeds are the most dangerous part and can cause vomiting, seizures, and liver failure.
- Oleander, Azaleas, and Rhododendrons: Often found in neighborhood gardens, these beautiful shrubs contain potent toxins that affect the heart and can lead to serious cardiac problems.
- Tulips and Hyacinths: The bulbs of these popular spring flowers are the most toxic part. If a dog digs one up and chews on it, it can cause intense oral irritation, drooling, and stomach upset.
- Marijuana: As cannabis becomes more common in households, so do accidental exposures. Ingestion can cause disorientation, vomiting, tremors, and, in severe cases, seizures or coma.
3. Human Foods
It’s natural to want to share a treat with your furry friend, but many human foods can cause serious health complications for pets.
- Chocolate: This well-known danger contains theobromine, a compound that is toxic to dogs. Dark chocolate and baking chocolate are the most hazardous.
- Grapes and Raisins: These can cause sudden kidney failure in dogs, even in very small amounts.
- Xylitol: This sugar substitute is a major threat found in sugar-free gum, candy, some peanut butters, and baked goods. In dogs, it causes a severe drop in blood sugar that can lead to seizures and liver failure. Always read ingredient labels.
- Onions, Garlic, and Chives: These ingredients, common in our cooking, can damage a pet’s red blood cells and lead to anemia.
- Macadamia Nuts: These can cause weakness, tremors, vomiting, and an elevated body temperature in dogs.
- Alcohol: Even a small amount of an alcoholic beverage can cause intoxication, vomiting, respiratory distress, and even death in pets.
4. Household Cleaning Products
The supplies we use to keep our homes clean often contain harsh chemicals. Bleach, ammonia, toilet bowl cleaners, and drain openers can cause chemical burns in the mouth and throat, respiratory distress, and internal damage if ingested. It’s best to keep your pet in another room while you clean and wait until all surfaces are dry before letting them back in.
5. Pest Control Products
Anything designed to kill pests—like rodenticides, insecticides, and snail bait—is also extremely dangerous for pets. These poisons are often made with tasty ingredients to attract pests, which also makes them appealing to dogs and cats. Rodenticides are particularly deadly, causing internal bleeding or neurological damage. It is always safest to use pet-friendly alternatives or place these products in areas that are completely inaccessible to your animals.
6. Antifreeze
Ethylene glycol, the main ingredient in most automotive antifreeze, has a sweet taste that pets find attractive. Tragically, even a small lick can be fatal, causing acute kidney failure. Symptoms start with a “drunken” appearance and progress quickly. Always clean up antifreeze spills immediately and store containers securely.
7. Batteries
Batteries, especially the small button-cell types found in toys and key fobs, are a serious hazard. If chewed or swallowed, the corrosive acid inside can leak and cause severe chemical burns to the mouth, esophagus, and stomach.
8. Potpourri
Both liquid and dried potpourri can be harmful. Liquid potpourri often contains detergents that can cause chemical burns if licked or ingested. Dried potpourri, while less corrosive, can still cause gastrointestinal upset or an intestinal blockage if eaten.
9. Fabric Softener Sheets
The strong, fresh scent of dryer sheets can attract a curious pet. However, they contain detergents that can cause mouth ulcers and stomach irritation if chewed or swallowed.
10. Fertilizers and Cocoa Mulch
Many garden products can be toxic if your pet decides to sample them. Some fertilizers contain harmful chemicals, while even “natural” options like bone meal can form a hard, concrete-like mass in the stomach and cause a blockage. Cocoa mulch is another major risk; it’s made from cacao shells and contains theobromine, the same substance that makes chocolate toxic to dogs.
