Top 10 Pet Toxins 

| March 27, 2026

In honour of Pet Poison Prevention Week, it’s the perfect time to raise awareness about the everyday items that can put our pets at risk. 

Each year, the ASPCA Animal Poison Control Center analyzes hundreds of thousands of cases to identify the most common toxic exposures. The latest 2025 data shows a clear trend: many of the top toxins are things we use every day at home. 

Here are the top 10 pet toxins and how you can help keep your pets safe. 

1. Over-the-Counter(OTC) Medications

Pain relievers like ibuprofen and naproxen remain the leading cause of pet poisonings. Vitamins and supplements are also a growing concern, especially when pills are accidentally dropped or left within reach. 

Prevention tip: Store all medications securely and never leave them unattended.

2. Food and Drink

Common toxic foods include: 

  • Xylitol (found in sugar-free gum and protein products)  
  • Grapes and raisins  
  • Onions and garlic  

Prevention tip: Avoid sharing human food and keep snacks safely stored. 

3. Human Prescription Medications

Medications for heart conditions, mental health, and ADHD are frequently involved in pet exposures. 

Prevention tip: Keep prescriptions in sealed containers and out of reach. 

4. Chocolate

Chocolate continues to be one of the most common toxins—especially for dogs who may eat large quantities if given the chance. 

Prevention tip: Keep chocolate products stored securely, especially during holidays and celebrations. 

5. Veterinary Products

Flavoured chewable medications can be appealing to pets, increasing the risk they’ll consume an entire package. 

Prevention tip: Store pet medications safely and follow dosing instructions carefully.

6. Plants and Fungi

Many common houseplants can be toxic if ingested. While exposures have decreased slightly, they remain a concern. 

Prevention tip: Research plants before bringing them into your home. 

 7. Rodenticides

Rodent control products can be extremely dangerous if pets are exposed directly—or indirectly through rodents. 

Prevention tip: Use pet-safe alternatives and place products in secure locations. 

8. Household Products

Items like deoxidizer packets, batteries, and cleaning products continue to pose risks. 

Prevention tip: Keep household items stored safely and dispose of packaging promptly. 

 9. Insecticides

Improper use or storage can lead to accidental exposure. 

Prevention tip: Always follow label instructions and store products out of reach. 

10. Recreational Drugs

While some exposures are decreasing, others—like certain mushrooms and substances—are on the rise. 

Prevention tip: Keep all substances securely stored and never leave them unattended. 

What To Do If Your Pet Is Exposed

If you think your pet has ingested something toxic, don’t wait. Contact your veterinarian immediately. 

Prevention Starts at Home

The most important takeaway? Many of the most dangerous toxins are already in our homes. By staying informed and taking simple precautions, you can help protect your pet from preventable emergencies.
