Unfortunately, accidental and intentional poisoning of pets happens every year in the United States. The toxicology laboratory at the Michigan State University Veterinary Diagnostic Laboratory, part of the College of Veterinary Medicine, conducts thousands of tests annually to help veterinarians and owners diagnose toxins involved in poisoning incidents. Learning more about common dangers and taking preventative steps to reduce your pet’s access to harmful substances can help you make your pet safer.

If you believe your pet is showing signs of poisoning, contact a poison control hotline immediately, follow their instructions, and seek veterinary medical help. If your pet has vomited, bring a sample with you. If possible, also bring a sample (including packaging) of what your pet has ingested.

Pets & Poison Control: Additional Information

*A Special Note About Medications

Keep any and all human medications securely out of the reach of pets and do not give your pet a medication designed for humans without instruction from your veterinarian.

Animals metabolize drugs differently and even drugs that we consider very safe for us can be deadly to our pets with just a small dose.

In addition to the drugs listed above, other common medications potentially lethal for pets include anti-cancer drugs, antidepressant or anti-anxiety medications, sleep aids, amphetamines (e.g. to treat ADD/ADHD), vitamins, and diet pills.

**An Important Notice About Rodenticides

There is little time for error if bromethalin is ingested by a pet. Contact a pet poison hotline immediately and seek veterinary treatment.

Recent regulation changes by the Environmental Protection Agency (EPA) require that manufacturers of rodenticides for consumer use stop using second-generation or long-acting anticoagulants. Manufacturers must also contain bait in tamperresistant bait stations. Pellets and other forms of bait that cannot be secured in bait stations are prohibited.

The manufacturer of D-Con products has complied with the new EPA regulations and has stopped producing prohibited anti-coagulant products. These products are no longer available at retailers.

The new generation of rodenticides currently on the market often use bromethalin, a toxin for which there is no antidote. There is also no test to detect it—except for a postmortem exam. Bromethalin is a fast-acting neurotoxin.

Because consumers may have anticoagulant and/ or bromethalin products in their homes, having the container available to provide information to poison hotline professionals and your veterinarian is immensely helpful and will determine the appropriate treatment for your pet in the event of accidental ingestion.

A Poison Control Success Story

Luke 2

Meet Luke. When he was just 6 months old, this pit bull mix got into some trouble. While visiting family out of town, his owner brought him inside through the garage. As she looked for a towel to wipe Luke’s paws before she took him off the leash, the owner heard him eating something. She turned to find him with his face in a plate of rodenticide.

The owner immediately pulled him away and removed the pellets he hadn’t swallowed from his mouth. She rushed him inside and confirmed with the homeowner that the green pellets were in fact rodenticide. The poison container was quickly located and while she called a poison helpline, the homeowner called his local veterinary clinic. With instructions to get to the clinic right away, Luke was immediately loaded into the car for a 10 minute drive to the clinic.

Upon arrival, Luke was weighed and taken back to the exam room. The veterinarian induced vomiting until Luke’s stomach was empty and confirmed that he had eaten several pellets.

Luke’s owner followed the veterinarian’s instructions carefully. This included giving Luke vitamin K daily and making a follow-up visit with his regular veterinarian. During that appointment, Luke’s doctor was happy to tell his owner Luke was a perfectly healthy puppy.

This may not seem like a story about luck, but it was fortunate that the rodenticide Luke ate was an anticoagulant product and not one that uses bromethalin. And not all owners are lucky enough to catch their pets in the act of eating poison. Quick thinking, remaining calm, making the right phone calls, and seeking medical treatment immediately all helped this story to have a happy ending.
