The Most Common Poisons for Pets: A Guide to Prevention and Treatment

Learn about common pet poisons and how to keep your pet safe and healthy!

Accidents happen, and sometimes our furry friends get into things they shouldn't. Keeping your furry friend safe is a top priority, and that includes being aware of common household hazards. 

Knowing the most common pet poisons can help you prevent accidents and understand what to do in an emergency, allowing you to act quickly and potentially save your pet's life. While many of these substances can seem harmless to us, they can be incredibly dangerous to pets.

Here's a breakdown of some of the top offenders:

1. Chocolate:

Chocolate is a popular treat for humans, but it can be dangerous for pets. The theobromine in chocolate affects the heart, nervous system, and kidneys. Dark chocolate, baking chocolate, and unsweetened cocoa powder pose the greatest risk,  followed by semisweet and milk chocolate. White chocolate contains minimal theobromine. Signs of chocolate poisoning include vomiting, diarrhea, restlessness, tremors, seizures, and heart problems.

2. Grapes and Raisins:

These seemingly innocent fruits can cause serious kidney damage in dogs. Even small amounts can be dangerous. The toxic substance in grapes is unknown, but it can be found in a variety of products, including granola bars and raisin paste. Signs include vomiting, lethargy, decreased appetite, and increased thirst and urination.

3. Ibuprofen and Other NSAIDs:

Over-the-counter pain relievers like ibuprofen can be very dangerous for pets, especially cats. They cause stomach irritation, kidney damage, and even liver failure. Symptoms include vomiting, diarrhea, lethargy, loss of appetite, and blood in the urine.

4. Xylitol:

This sugar alcohol/substitute, commonly found in many sugar-free products like gum, candy, and toothpaste, is highly toxic to dogs. Xylitol causes a rapid release of insulin, leading to a rapid drop in blood sugar (hypoglycemia). Symptoms include vomiting, lethargy, tremors, seizures, and liver damage.

5. Bromethalin:

This rodenticide is highly toxic to pets, especially cats. It affects the nervous system and can cause tremors, seizures, paralysis, and death. Symptoms include lethargy, weakness, tremors, seizures, and coma.

6. Vitamin D3 (Cholecalciferol):

This vitamin, often found in supplements and some rodenticides, can cause dangerously high levels of calcium in the blood, leading to kidney damage and bone problems. Symptoms include vomiting, loss of appetite, lethargy, increased thirst, increased urination, and muscle weakness.

7. Marijuana (THC):

The psychoactive compound THC, found in marijuana, can cause a range of effects in pets, including lethargy, vomiting, disorientation, and changes in behavior. Marijuana, especially edibles and concentrates, can cause significant problems for pets. 

8. Onions/Garlic:

These members of the Allium family contain compounds that can damage red blood cells in dogs and cats, especially if consumed in large quantities, causing anemia. Symptoms include vomiting, diarrhea, lethargy, loss of appetite, weakness, and pale gums.

9. Anticoagulant Rodenticides:

These poisons, found in rat and mouse bait, interfere with blood clotting and often lead to internal bleeding and potential death. Symptoms may not appear for several days and include lethargy, bleeding gums, nosebleeds, and bruising.

10. Carprofen (Rimadyl):

This veterinary-approved pain reliever can be toxic in large doses. While commonly prescribed for pain relief in pets, it can cause stomach ulcers, kidney damage, and other serious side effects if ingested in large quantities.

Preventing Poisoning:

  • Keep medications and dangerous substances out of reach: Store all medications, vitamins, supplements, and household cleaners securely, ideally in locked cabinets.
  • Be aware of food and treats: Don't share human food with pets, especially those known to be toxic. Pay attention to ingredients in treats and avoid those containing harmful substances.
  • Read Labels Carefully: Be aware of the ingredients in human and pet medications and foods.
  • Be Vigilant About Garbage: Securely store garbage, especially food scraps that could be toxic to pets.
  • Keep a close eye on your pet: Supervise your pet when they are outside, especially in areas where they could encounter rodenticides or other toxins. Be cautious about using rodent baits and pesticides in your home and research the toxicity of any plants you bring into your home or garden - try to keep plants, both indoor and outdoor, away from your pet.
  • Be proactive: Know the signs of poisoning and contact your veterinarian immediately if you suspect your pet has ingested something toxic.

What to Do in an Emergency:

Remember, time is crucial when it comes to treating pet poisoning. Don't hesitate to seek immediate veterinary care if you suspect your pet has ingested a poisonous substance.

If you suspect your pet has ingested any of these poisons, contact your veterinarian or the ASPCA Animal Poison Control Center immediately at 1-888-426-4435. Be prepared to provide information about the type of poison ingested, the amount consumed, and the time of ingestion.

Prevention is key! By being aware of the common poisons and taking precautions, you can help protect your pet from accidental ingestion and can help keep your furry friend safe and healthy.
