Dog Rat Poison Toxicity Calculator
Assess the risk when your dog eats rat poison or rodenticide — by type, amount and dog weight.
What Is the Dog Rat Poison Toxicity Calculator?
Assess the risk when your dog eats rat poison or rodenticide — by type, amount and dog weight.
Rat poison (rodenticide) is one of the most common causes of serious dog poisoning. Different rodenticide types work through different mechanisms — anticoagulants, neurotoxins, and hypercalcaemia agents — each requiring different emergency treatments. Identifying the type of poison is critical.

How It Works
Anticoagulant rodenticides (the most common type) inhibit vitamin K epoxide reductase, blocking the recycling of vitamin K and preventing synthesis of clotting factors II, VII, IX, and X. Second-generation anticoagulants (brodifacoum, bromadiolone) are far more potent and persistent than first-generation (warfarin), requiring vitamin K1 treatment for 4–6 weeks. The minimum toxic dose for brodifacoum in dogs is approximately 0.25mg/kg. Sources: ASPCA Animal Poison Control, Plumb's Veterinary Drug Handbook.
