Seasonal Hazards for Pets: Fall Edition

As the crisp fall air settles in and the days grow shorter, pet owners often face unique challenges when it comes to keeping their furry companions safe. At Oklahoma Veterinary Specialists, we are committed to educating pet owners about the seasonal hazards that can pose serious risks to the health of their pets. Fall is a time when rodenticides, cold weather poisons, toxic mushrooms, and encounters with wildlife are more prevalent, each presenting distinct dangers. Here, we explore these threats and provide guidance on how to keep your pets safe during this time of year.

1. Rodenticides: A Hidden Threat

Rodenticides, commonly known as rat poisons, are widely used during the fall as rodents seek shelter in homes and garages. These poisons are highly toxic to pets, particularly dogs and cats who may accidentally ingest them. The primary types of rodenticides include:

• Anticoagulants: These interfere with the blood's ability to clot, leading to internal bleeding. Common symptoms include lethargy, pale gums, coughing, and difficulty breathing.
• Neurotoxins: Such as bromethalin, which affects the nervous system, can cause tremors, seizures, and paralysis.
• Hypercalcemic agents: These cause a dangerous increase in calcium levels, leading to kidney failure and cardiac issues.

Pet owners should be vigilant about keeping rodenticides out of reach. Even if not directly accessible, secondary poisoning can occur if a pet consumes a rodent that has ingested poison. If you suspect your pet has ingested rodenticide, immediate veterinary care is crucial. Treatment typically involves decontamination, activated charcoal administration, and supportive care like IV fluids and medications to manage symptoms.

2. Cold Weather Poisons: Antifreeze and Ice Melts

As temperatures drop, antifreeze (ethylene glycol) and ice melts become more common in households. Unfortunately, these substances are extremely toxic to pets.

• Antifreeze: It has a sweet taste that can be appealing to animals, but even a small amount can cause kidney failure and be fatal if not treated promptly. Symptoms of antifreeze poisoning include vomiting, lethargy, uncoordinated movements, and seizures. Immediate veterinary intervention is necessary, as treatment often involves inducing vomiting, administering activated charcoal, and providing IV fluids and specific antidotes.
• Ice Melts: These typically contain chemicals like sodium chloride, calcium chloride, or magnesium chloride, which can cause gastrointestinal irritation, electrolyte imbalances, and burns on the paws. To minimize risks, opt for pet-safe ice melt products and rinse your pet’s paws after walks in treated areas.

3. Toxic Mushrooms: A Seasonal Danger

Mushrooms flourish in the damp, cool conditions of fall. While many mushrooms are harmless, some are highly toxic and can pose a severe threat to pets. The toxicity of mushrooms varies, with some causing gastrointestinal upset, while others can lead to liver failure, neurological symptoms, or even death.

Common toxic varieties include:

• Amanita species: Known as “Death Cap” and “Destroying Angel,” these are extremely toxic and can cause severe liver damage.
• Inocybe and Clitocybe species: These contain muscarine and can cause salivation, lacrimation, urination, and diarrhea (SLUD syndrome).
• Psilocybin mushrooms: Known for their hallucinogenic effects, these can cause ataxia, tremors, and seizures in pets.

Because it can be difficult to identify mushrooms accurately, it is best to assume all wild mushrooms are toxic and prevent your pets from eating them. If ingestion occurs, prompt veterinary attention is required, as treatments may include decontamination, activated charcoal, and symptomatic care.

4. Wildlife Hazards: Encounters with Critters

As wildlife prepares for winter, encounters between pets and wild animals can increase. Squirrels, raccoons, skunks, and even snakes may come closer to residential areas in search of food and shelter, potentially leading to dangerous interactions.

• Raccoons and Skunks: Both species can transmit diseases like rabies and leptospirosis, as well as parasites such as roundworms.
• Snakes: Venomous snakes like copperheads and rattlesnakes are still active in the fall. Snake bites can cause severe pain, swelling, and even death in pets if not treated promptly.
• Porcupines and Squirrels: Porcupines can embed quills in a pet’s face and body, which require professional removal. Squirrels may bite if cornered, leading to wounds that can become infected.

To reduce the risk of encounters, supervise your pets outdoors and avoid areas known for wildlife activity. Keeping your yard clear of food scraps and sealing entry points to garages and sheds can also help deter wildlife from coming too close.
