How to Poison Rats Witihout Poisoning a Dog

There no such thing as a rat poison that is completely safe for dogs.

Poisons including warfarin, brodifacoum, bromadiaoline, difacinone and difethialone kill rats by interfering with their blood clotting; they act in a similar way on dogs, resulting in bleeding, seizures, or damage to the kidneys and other vital organs.

Instead, consider using bromethalin.

As a dog owner, you should place the poison only in places that are inaccessible to your pet, or consider leashing it.

Be careful when using rat poison around pets.
  1. Minimize the time you must leash or confine your dog by using bromethalin, a single-dose neurotoxin that usually kills rodents within 24 to 36 hours of consumption.

  2. Calculate the lethal dose for your dog, and adjust the amount of bait you drop accordingly. The minimum lethal dose of bromethalic bait for a dog is 25 grams per kilogram of body weight, meaning that a 5 kg dog would have to consume five to six packages of bait to reach toxic levels.

  3. Monitor your dog carefully if you have recently set out rat poison.

    If you suspect your dog may have ingested poison--symptoms include muscle tremors, excitability, running fits and seizures--induce vomiting immediately, before the poison is absorbed.
