How It Works
Brodifacoum is a second-generation anticoagulant rodenticide that prevents Vitamin K recycling, causing the blood to lose its ability to clot. Unlike first-generation warfarin, brodifacoum accumulates in body fat and has an extremely long half-life of up to 120 days. A single ingestion causes prolonged anticoagulation.
The critical danger is that symptoms — internal bleeding, bruising, bloody discharge — do not appear for 3-7 days after ingestion. By this point the dog can be critically ill. Treatment with Vitamin K1 must begin before symptoms appear for the best outcome. Any suspected ingestion should be treated as an emergency requiring immediate veterinary attention.
