# 21 Fall Hazards Dog Owners Must Watch Out For This Season
Autumn transforms yards and parks into beautiful landscapes, but the season introduces specific dangers to dogs. Dog owners need to identify these hazards and protect their pets during fall months.
**Toxic Plants and Fungi**
Fall gardens harbor multiple poisonous plants. Sago palms, lilies, and autumn crocus contain toxins that damage dog livers and kidneys. Mushrooms and toadstools pose another serious threat. Many wild fungi species grow after fall rains, and dogs can ingest them while sniffing or playing outdoors. Even small amounts of certain mushroom species like Amanita phalloides cause fatal liver failure in dogs. Keep dogs away from wooded areas with heavy fungal growth, and monitor your yard carefully.
**Seasonal Plants and Decorations**
Halloween and fall decorations introduce new risks. Chocolate used in fall treats remains toxic to dogs, affecting their hearts and nervous systems. Decorative gourds and pumpkins, while not inherently poisonous, can cause intestinal blockages if dogs consume large pieces. Corn cobs used in fall decorations present choking hazards. Keep all decorative items and treats away from curious dogs.
**Temperature Fluctuations and Coat Changes**
Fall weather swings between warm afternoons and cold mornings. Dogs with thin coats need sweaters during chilly periods. Senior dogs and small breeds struggle more with temperature changes. Monitor your dog's behavior for shivering or reluctance to go outside. As temperatures drop, provide adequate shelter and limit outdoor time appropriately.
**Parasites and Pests**
Fall doesn't eliminate parasites. Fleas, ticks, and mosquitoes remain active in many regions during autumn months. Some areas see increased tick populations as wildlife moves through yards. Continue flea and tick prevention year-round. Discuss fall parasite control with your veterinarian, as recommendations vary by location.
**Harvest and Food Hazards**
Fallen apples, walnuts, and other autumn produce attract dogs. Apple seeds contain cyanogenic compounds, though the quantity in a few seeds rarely causes harm. Black walnuts and English walnuts contain mycotoxins causing tremors and seizures. Grapes and raisins from fall harvests remain toxic even in small amounts. Remove fallen fruit and nuts from yards where dogs play.
**Reduced Daylight and Exercise Changes**
Shorter days mean less daylight for outdoor activities. Dogs needing regular exercise may gain weight or develop behavioral issues without adequate activity. Adjust schedules to maximize daylight hours for walks and play. Indoor enrichment becomes more important as outdoor time decreases.
**Allergies and Respiratory Issues**
Mold spores spike during fall. Dogs with allergies experience itching, ear infections, and respiratory problems. Falling leaves trap moisture, creating mold growth in yards. Wipe your dog's paws after outdoor time to remove mold spores and allergens. Ask your vet about allergy management if symptoms appear.
**Road Salt and De-icers**
Some regions apply early de-icer products before winter arrives. These chemicals irritate dog paws and cause gastrointestinal upset if ingested. Wash paws thoroughly after walks on treated surfaces.
Fall outdoor activities strengthen bonds with your dog, but seasonal awareness prevents injuries and illness. Review these hazards before the season progresses, and discuss fall-specific care with your veterinarian. Regular check-ins during seasonal transitions help catch health issues early.
