Human foods: Even if they’re not technically toxic, some foods are not well tolerated by dogs. High-fat items, for example, are associated with pancreatitis in some dogs, particularly when eaten in large amounts.

Food scraps: Pits, peels, cobs, spoiled leftovers, or uncooked items can cause obstructions, infections, or toxic reactions. As a general guideline, items unsafe for people often pose risks for dogs as well.

Utensils and knives: Unwashed dishes or knives left within reach can be tempting and dangerous for curious dogs. Reducing access to sharp tools lowers the risk of injury.

Trash and wrappers: Discarded food and packaging can cause problems, from intestinal blockages to suffocation. An empty chip bag, for example, can get stuck over a dog’s face while they lick out crumbs. Using secure, pet-resistant trash containers helps reduce this risk.

Cleaning products: Toxicity depends on the product, concentration, and amount involved. Even natural or homemade solutions can pose a risk. Essential oils, for example, have been associated with problems when inhaled or ingested by dogs. Secure storage, fully dried surfaces, and minimizing exposure to fumes help reduce risk.

Toilets: Open toilets may expose dogs to cleaners or infectious agents. Keeping lids closed reduces this exposure

Medications: Both human and veterinary medications can be dangerous if taken inappropriately or without supervision. Some human medications even contain sweeteners that are toxic to dogs. Medications should only be given under your veterinarian’s direction, and always store medicines securely to prevent accidental ingestion.

Cosmetics and hygiene products: Lotions, creams, cotton balls, Q-tips, feminine products, and even hair ties can all cause health problems if swallowed. Limiting access to these items helps reduce the risk of ingestion.

Electrical cords and open flames: Puppies and new pets are more likely to chew cords or accidentally contact open flames (candles).

Small objects: Toys, socks, coins, batteries, and tools can be swallowed, can be swallowed, leading to obstructions or chemical injuries.

Holiday decorations: Seasonal décor often includes chewable or toxic items, plan ahead and creating a “dog-safe zone” can limit exposure.

Hidden toxins: Play-Doh, adhesives, mothballs, some essential oils, and potpourri can cause illness if ingested.

Structural hazards: Stairs, balconies, low windows, and pools or ponds may pose fall or drowning risks for curious pets.

Chemicals: Antifreeze, ice melt, fertilizers, pest control products, fuels, paints, and compost can be toxic. Secure storage and observing label-listed drying or curing times before allowing pet canes to treated areas help reduce exposure.

Lawn equipment: Power tools and machinery pose injury risk. Keeping dogs separated from active work areas reduces the chance of accidental injury.

Plants: Some plants are toxic to dogs, and severity depends on the plant, part, and growth stage. For example, green parts of tomato plants are toxic, but ripe tomatoes are generally considered safe. Plant identification apps like PlantNet and veterinary toxicology resources such as ASPCA toxic plant resource, can be helpful resources.

Wildlife and carcasses: Frogs, snakes, insects, or dead animals may carry toxins, infections, or poison residues (if killed by bait).

Standing water: Puddles or ponds can harbor bacteria and parasites that may cause illness in dogs.
